Persimmon is a high value climacteric fruit and deteriorate rapidly after harvest. Therefore, an investigation on extending storage life of persimmon fruits using active packaging technology was done with the following treatments viz., T1 (Control), T2 (Cloth bag + 3g activated charcoal), T3 (Non-woven pp bag + 3g Activated charcoal), T4 (Butter paper bag + 3g Activated charcoal), T5 (Polypropylene + 3g Activated charcoal), T6 (Cloth bag + 6g KMnO4), T7 (Non-woven pp bag + 6g KMnO4), T8 (Butter paper bag + 6g KMnO4) and T9 (Polypropylene + 6g KMnO4). These were stored at 4±1°C and 85-90% RH and analyzed for different physiochemical properties at 10-day intervals. Polypropylene packaging with 3g Activated charcoal or 6g KMnO4 resulted in the longestshelf life and good quality fruits at more than 50 days of storage. Modified packaging with polypropylene + 3g Activated charcoal preserved fruit firmness, greater β-carotene content in pulp and lowest PLW (%), while fruits packed in Polypropylene + 6g KMnO4 resulted in the highest pH, ascorbic acid, peel β-carotene and pectin content and lowest TSS, total and reducing sugar content. The highest BCR amongst various treatment combinations was found in fruits packaged in Polypropylene + 6g KMnO4 on the 70th day of storage

In order to identify suitable species that can be used for cross-breeding and propagation for horticulture purposes four endemic and epiphytic orchid species, Aerides crispa Lindl., A. maculosa Lindl., A. ringens Fischer. and A. odorata Lour. were studied by comparing their leaf morphology, stomata, pigmentation, and biomolecules. Standard methods were used for the evaluation. A. odoratum, native to the lowest altitude, was characterized by thin, long leaves with the lowest specific leaf area and higher water content. Among the four species studied, stomata were bigger in size and less in number in A. odoratum. Maximum total soluble sugars, soluble proteins, amino acids, and starch contents, an indicator of a better photosynthesis rate were noted in A. odoratum. Total chlorophyll and carotenoid contents per unit leaf area were higher in A. odoratum and A. ringens. Our results concluded that variation in environmental temperature, humidity, sunlight intensity, and exposure of orchids at different altitudes may cause alteration in traits that can be inherited over a period.

The present study was carried out with the aim to develop a plant growth-promoting rhizobacterial inoculant for improving the growth of radish. A total of 20 rhizobacteria were isolated and then tested for multifarious plant growth-promoting traits. The isolates exhibited tricalcium phosphate and zinc solubilization, production of siderophores, auxins, ammonia and growth on different nitrogen free medium. Out of 20 isolates, two potential bacterial isolates (RM3 and RL3) were selected on the basis of PGP traits for evaluation of their potential to promote growth of radish under pot conditions. In green house experiment, these isolates when used as consortium showed a significant improvement in soil enzymatic activities (viz. dehydrogenase: 12.99 µg TPF formed h-1 g of soil-1, alkaline phosphatase: 11.94 µg PNP formed h-1 g of soil-1 and urease: 401.65 µg urea hydrolyzed formed h-1g of soil-1) and plant growth parameters (shoot length: 38.76 cm, leaf area: 267cm2, fresh leaf weight:106.05 g, dry leaf weight:1.23 g, number of leaves per plant: 23, fresh root weight:111.69 g, dry root weight: 2.06 g, root length: 34.04 cm and root diameter: 3.33 cm) relative to control as well as other bioinoculants. These bacteria were tentatively identified as Bacillus (RM3) and Pseudomonas (RL3) on the basis of biochemical tests.

The leaf yellowing and senescence during micro-propagation reduces the shoot proliferation rates with every sub-culture in peach rootstock (Prunus spp.). The effect of culture media and supplements on the proliferation of cultures during the micro-propagation of two peach rootstocks ‘Sharbati’ and ‘Flordaguard’ was studied. In both Prunus genotypes, the proliferated cultures decreased from 77.3% and 67.0 % after the first sub-culture to 35.3 % and 27.3 % after the third sub-culture in ‘Sharbati’ and ‘Flordaguard’, respectively. QL medium significantly improved the proportion of proliferated cultures over MS, WPM, DKW and the modified MS media. The highest proliferated cultures (79.0% and 70.7%) and shoot number per culture (4.2 and 3.7) were recorded after the third subculture, in ‘Sharbati’ and ‘Flordaguard’, respectively with QL medium. Both the rootstocks varied in their response to iron chelates. The higher proliferation rates were obtained with MS medium by substituting Fe-EDTA (0.1 mM) with Fe-EDDHA (0.1-0.3 mM) in ‘Sharbati’ and with Fe-Na EDTA (0.1 mM) in ‘Flordaguard’. In‘Sharbati’, the highest proliferated cultures (44.3%) after the third subculture were observed with Fe-EDDHA (0.3 mM). In ‘Flordaguard’, the highest proportion of proliferated cultures (45%) after the third subculture was recorded with Fe-Na EDTA (0.1 mM). Adding silver nitrate (3 mM) improved the shoot proliferation rates to the highest levels (63% and 51%) after third subculture in ‘Sharbati’ and ‘Flordaguard’, respectively. The highest rooting (34.3% and 38.0%) and number of roots per shoot (2.2 and 2.5) were recorded with 3.75 mM of IBA in ‘Sharbati’ and ‘Flordaguard’, respectively.

Papaya (Carica papaya L.) is a tropical fruit crop with commercial importance due to its nutritional andmedicinal value. The long generation time required by papaya plants during the breeding process significantly slows crop improvement, and developing a variety takes 15-16 years (7-8 generations). As a solution in this direction, using plant bioregulators (PGR) to improve seed maturity in conjunction with the embryo culture technique may aid in reducing the time between fruit set and seedling establishment. We investigated the effect of ethrel, abscisic acid (ABA), and methyl jasmonate (MeJa) in different concentrations during early fruit development on hastening embryo maturity followed by embryo culture for shortening the breeding cycle of dioecious papaya var. Pusa Nanha. Fruits after 60 and 75-days old fruit (DOF) were treated with ethrel (100, 120 ppm), abscisic acid (10-6, 10-4 M), and MeJA (10-5, 10-3 M); the effect of treatments was observed after 15 days of PGR application. Among the treatments, ethrel 120 and 100 ppm at 75 DOF were found to be effective fo hastening seed maturity, as measured by seed colour (light brown), embryo formation (85%), and embryo size (2.93 mm), maximum in vitro germination (85%), rapid shoot emergence (5.67 days), earliest radicle emergence(2.67 days), resulting in maximum plantlet regeneration (86.67%). The embryos isolated from the fruits treated with MeJA (10-5 M) showed the maximum number of roots (5.13), with 75.50 % plantlet regeneration. As a result, using the above method, the breeding cycle of papaya could be reduced to as low as 3 months, compared to the standard period of 6-9 months (from pollination to seedling establishment).

Aonla - ginger-sour orange juice blended RTS was prepared and standardized. Sensory evaluation of the juices revealed that a sour orange concentration of 4 % was accepted widely with a maximum score of taste (8.7±0.58), texture (8.7±0.58) and overall acceptability (7.7±0.58). The juice was clarified at 30oC for 72 h to increase the initial microbial load. Ultraviolet irradiation was applied to the standardized aonla - ginger-sour orange blended RTS through a developed UV reactor at 8 kJ/L and 0.58 kJ/L dosage levels. At each reactor circulation, the microbiological population was assessed. Total plate count (TPC) and yeast and mould count (YMC), which contributed to the initial load of the RTS were found to be 5.45 log CFU/ml and 6.22 log CFU/ml, respectively. TPC exhibited 5.45 log reductions (commercial sterility) after the third circulation at a UV dose of 8 kJ/L. The TPC and YMC did not significantly change at the dose level of 0.58 kJ/L, irrespective of the number of circulations.

Chrysanthemum is moderately sensitive to salt stress, and salinity largely affects its production. The experiment was undertaken at the research farm of the Division of Floriculture and Landscaping, ICAR-IARI, New Delhi, during the winter season. Ten chrysanthemum varieties were screened to understand their response to salt stress (150 mM NaCl) and tolerance mechanisms. Salt stress significantly affected osmolyte accumulation and physio-biochemical attributes of chrysanthemum varieties against control. Red Gold variety performed well in terms of growth and yield attributes, indicating its ability to tolerate the salt level of 150 mM NaCl. The highest leaf proline content was recorded in var. White Prolific followed by var. Tata Century. NaCl stress caused a 3/2-fold and 1/2-fold increase in the level of Na+ and K+ ions in leaf tissues of most varieties against control Shoot K+/Na+ ratio was recorded highest in variety Tata Century followed by variety Discovery. From the experiment, vars. White Prolific, Red Gold, Tata Century, and Discovery were found to be more tolerant due to better osmotic adjustments through the accumulation of proline, relative performance under salt stress for plant growth, flower yield, photosynthetic pigments and high K+/Na+ concentration to better sustain under saline condition than the susceptible varieties. PCA analysis revealed that the sum of principal components PC1 and PC2 explained 59.0% of the variations among the varieties. Plant height, chlorophyll content, and fresh weight number of branches had the highest positive loading value, i.e., ~0.7, and leaf proline content had the lowest loading value, i.e., ~0.08, indicating the strongest influence on PC1 and PC2.
菊花对盐胁迫中度敏感,盐度对其产量影响很大。该实验于冬季在新德里ICAR-IARI花卉栽培和园林绿化司的研究农场进行。通过筛选10个菊花品种,了解其对150mm NaCl盐胁迫的响应及其耐盐机制。盐胁迫显著影响菊花品种渗透物积累和生理生化特性。红金品种在生长性状和产量性状方面表现良好,表明其耐150 mM NaCl盐水平的能力。叶片脯氨酸含量最高的品种是白多产品种,其次是塔塔世纪品种。NaCl胁迫使大部分品种叶片组织中Na+和K+离子水平分别比对照升高3/2和1/2倍。植株K+/Na+比值以“塔塔世纪”最高,“发现”次之。从实验中可以看出。与敏感品种相比,白高产、红黄金、塔塔世纪和发现品种通过脯氨酸积累进行更好的渗透调节、在盐胁迫下植物生长的相对表现、花产量、光合色素和较高的K+/Na+浓度能更好地在盐条件下维持,从而具有更强的耐受性。主成分分析表明,主成分PC1和PC2的总和解释了品种间59.0%的变异。株高、叶绿素含量和鲜重枝数的正负荷值最高,为~0.7,叶片脯氨酸含量的正负荷值最低,为~0.08,说明对PC1和PC2的影响最大。

The present study focuses on the impact of active packaging technology on the Ney Poovan banana variety, aiming to extend its shelf life for export purpose. The experiment comprised four treatments: an ethylene absorber, a moisture absorber, a control group, and packaging in vacuum-sealed polythene bags. These banana samples were subsequently stored at two different temperatures, namely room temperature (RT) and 13.5°C. The results obtained from the experiment indicated that the fruits packed with an ethylene absorber exhibited an extended shelf life of 72 days when stored at 13.5°C. The fruits remained fresh for 20 days when stored at RT. These ethylene-treated fruits also displayed the highest pulp-to-peel ratio (PPR) of 7.34 when held at 13.5°C, while the highest acid content (0.673%) was registered at RT. On the other hand, the control group fruits stored at RT tended to show the highest TSS content (29oBrix). The fruits stored at RT, irrespective of the treatments exhibited the highest content of TSS (21.11oBrix). The physiological loss in weight increased gradually during storage in both temperatures but was low in fruits packed with moisture absorbers. Though the ethylene evolution rate increased towards extended storage in both temperatures, the concentration was less in fruits packed with ethylene absorber.

The experiment comprised four treatments: an ethylene absorber, a moisture absorber, a control group, and packaging in vacuum-sealed polythene bags. These banana samples were subsequently stored at two different temperatures, namely room temperature (RT) and 13.5°C. The results obtained from the experiment indicated that the fruits packed with an ethylene absorber exhibited an extended shelf life of 72 days when stored at 13.5°C. The fruits remained fresh for 20 days when stored at RT.

Cultivation of 'Red Globe' grapes are gaining popularity in India's mild tropical climate owing to its bold berries, attractive red colour, and better shelf life, thus fetching a better price in the market. 'Dogridge' is the preferred rootstock in India because of its wide adaptability to different soils and climatic conditions, besides its tolerance to drought and salinity. Though most of the commercial grape varieties are grafted on 'Dogridge' rootstock, the success of grafting 'Red Globe' onto 'Dogridge' is little, or it needs repeated grafting for vineyard establishment. Hence, to improve the grafting success on 'Dogridge' rootstock, we tried different combinations of scion treatments. The scions were treated with cytokinin compounds like kinetin or benzyl amino purine (BAP) or a combination of hormones with scion preconditioning or etiolating and compared with the control. Among these treatments, scions preconditioned on mother vines for five days combined with treating them with BAP @ 100 ppm for 60 seconds before grafting, improved the grafting success to 68%. Biochemical and enzyme studies also indicated higher activity of antioxidant enzymes like peroxidase and polyphenol oxidase in the same treatment. Scion preconditioning and BAP treatment helped better callus production and vascular connectivity between stock and scion, contributing to better graft success. The role of biochemical parameters and antioxidant enzymes in improving graft success has been discussed.

In this study, 51 hybrids were developed using Line × Tester mating design, including 17 lines and 3 testers. Analysis of variance for combining ability indicated that differences among parents were significant for all the characters under study except for days to first picking. The σ2 SCA were higher in magnitude than σ2 GCA for almost all the traits except for days to first picking, which indicates the predominant role of non-additive gene action. Lines viz., UHF CAP-23, UHF CAP-1 and UHF CAP-22 and 2 testers viz., Yolo Wonder and California Wonder were the most promising for yield per plant and the majority of yield contributing traits. The SCA effects for fruit yield per plant were significantly desirable in UHF CAP-30 × California Wonder, UHF CAP-2 × Solan Bharpur and UHF CAP-29 × Solan Bharpur. Heterosis over the standard check and other genetic parameters 3 cross combinations viz., UHF CAP-30 × California Wonder, UHF CAP-23 × Yolo Wonder and UHF CAP-22 × California Wonder performed well for a majority of yield and yield contributing traits. These hybrids can be recommended for cultivation after multi-locational testing.
本研究采用Line × Tester配种设计,选育了51个杂交种,包括17个品系和3个测试体。配合力方差分析表明,除首次采收天数外,各亲本间配合力差异均显著。除首采前数外,其余性状的σ2 SCA值均大于σ2 GCA值,说明非加性基因作用占主导地位。品系UHF CAP-23、UHF CAP-1和UHF CAP-22以及2个测试品系Yolo Wonder和California Wonder在单株产量和大多数产量贡献性状方面最有希望。超高频CAP-30 × California Wonder、超高频CAP-2 × Solan Bharpur和超高频CAP-29 × Solan Bharpur对单株果实产量的SCA效应显著。超高频CAP-30 × California Wonder、超高频CAP-23 × Yolo Wonder和超高频CAP-22 × California Wonder 3个杂交组合在大多数产量和产量贡献性状上均表现出良好的杂种优势。这些杂交种可在多地点试验后推荐栽培。
