The incidence of incompatibility signs in the grafting point can be delayed, and the analysis of phenols is used as an applicable early sign for the detection of graft incompatibility. Accordingly, this study mainly aimed to investigate compatibility/incompatibility in 10 commercial plum cultivars grafted on myrobalan and apricot rootstocks, followed by determining the role of phenols in graft incompatibility. The evaluated cultivars included Santarosa, Ghatreh tala, Shams, Dargazi, No. 16, No. 17, Laroda, Simka, Bokhara, and Stanley. The results showed significant differences in the stem diameter. The union graft location in Shams, Laroda, Simka, Stanley, and Ghatreh tala cultivars on apricot rootstock was thicker than the scions and stocks. Phenolic compounds in the union graft decreased in all plum cultivars on myrobalan rootstock in comparison with other sites. Finally, the most phenolic accumulation belonged to the union graft on Santarosa, Ghatreh tala, and Shams on apricot rootstocks. Therefore, it seems that phenolic compounds in plums can be used as a biochemical marker in graft incompatibility.

The Northeast region of India is endowed with diverse soil and agro-climatic conditions that are conducive to the growth of a large variety of temperate and tropical horticultural crops. Fruits, vegetables, and spices of the region are highly nutritious and have a market within and outside the country. The paper is an attempt to assess the potential of horticulture in the region. To gauge the state-wise and regional growth trend and variability in area and production of these crops during the period 2009-2019, Compound Annual Growth rates and Instability Index have been computed from secondary data. The study reveals a rising regional growth trend with low instability for the production of fruits and vegetables and moderate instability for spices. This indicates the possibility of sustainable development of horticulture in all the Northeast states through strategic planning. Fruits and spices of the region also have a market in Middle-East and neighbouring countries. However, lack of commercialisation, poor market intelligence, and linkages are impeding the growth of exports. To unleash the true potential of horticulture, it is imperative to develop infrastructure, modernise farming and establish seamless value chains with greater market integration.

Eggplant is popularly known as poor man’s vegetable. With respect to present situation of climatic challenges, fruit yield of eggplant is reduced due to drought or moisture stresses. In view of this condition, an experiment was aimed to study character association between yield and yield components in eggplant. The resultant outcome from correlation analysis computed among nine eggplant characters indicated that traits like plant height and total plant length at harvesting, fruit length and number of fruits per plant significantly correlated with fruit yield per plant. Whereas, traits like plant height and total plant length observed at harvesting stage, number of days for flower initiation, number of primary branches, fruit length and average fruit weight were significantly associated with fruit yield per plant under moisture stressed condition.

Giant Himalayan lily (Cardiocrinum giganteum Wall.) is a perennial bulbiferous herb of Liliaceae and an endemic species in the eastern Himalayan region, which has become one of the new flower crops because of its high ornamental value. The present investigationwas conducted to study pollen morphologyi.e., fresh pollen grains size was measured in different media, viz., water, acetocarmine, glycerol and without any medium (dry). The pollen grains of Giant Himalayan lily exhibited the average size (length x width) of (22.64 x 19.72μ) in water suspension. The result revealed that in glycerine and dry condition shape of pollen grains was perprolate. However, in water and acetocarmine it looked was round in shape. The result also shown that highest pollen germination (54.70%, 63.69%) and pollen tube growth (89.24μ, 175.85μ) in 10% sucrose solution for 12 hours and 24 hours respectively. In control light treatments, red light was found to be best in pollen germination and pollen tube growth.

India is the second largest producer of tomato with 11 per cent global share and cultivated on an estimated area of 0.76 million hectares with productivity of 24 tonnes per hectare. Less than 1% of the produce is processed when compared to 26% in other major producing countries. Of the estimated more than 41 million tonnes of tomato processed globally, only 130,000 tonnes were processed in India and domestic demand for processed tomato products is expanding at an estimated 30% annually. At present traditional fresh market tomato cultivars are being processed though such cultivars are unsuitable for processing. Processors in India are looking for high yielding tomato cultivars with high total soluble solids (5-6 º Brix), acidity not less than 0.4%, pH less than 4.5 and uniform red colour with a/b colour value of at least 2. In addition, firm fruited tomato cultivars with joint less pedicel (j2) which facilitate mechanical harvesting or rapid hand picking. ICAR-Indian Institute of Horticultural Research has recently developed two high yielding F1 hybrids in tomato viz: Arka Apeksha and Arka Vishesh suitable for processing. On evaluation for three years, both the hybrids recorded good level of total soluble solids (4.5-5º Brix) and colour value of 2. Further, both the hybrids had high yield potential (80-90 tonnes / hectare) with triple disease resistance to tomato leaf curl disease, bacterial wilt and early blight. Arka Apeksha and Arka Vishesh were also bred with jointless pedicel making them suitable for mechanical harvesting. Our experimental studies on vine storability revealed that all the fruits were intact on plants even 110 days after transplanting in the main field facilitating once over harvest.

Arecanut (Areca catechu L.) commonly called as betel nut is a high value commercial cropof coastal and Malnad region of Kerala and Karnataka. The present study was carried outat Agricultural and Horticultural research station Sringeri, UAHS Shivamogga in 2018. Thestudy attempts the correlation studies in the germplasm will help to understand the mutualrelationship among various traits and thereby assist in selecting the character contributingto the yield. In addition to this the selection for yield directly is ineffective as yield is affected by many other traits. The highest positive significant for the association of fruit yield per palm was with the fresh kernel weight per palm (0.96g) followed by dry weight of husk per palm (0.89g) and fresh weight of husk per palm (0.89g). Path analysis revealed that nineteen out of thirty-four characters recorded that fruit volume (2.40cc) had highest positive direct effect on fruit yield per palm followed by fresh fruit weight (2.17g) and breadth of leaf sheath (2.11m). It can be concluded that growth and yield characters may be considered in selection criteria for the improvement of yield in arecanut.

In mango, leaf and fruit volatile aroma profiles are variety specific which can be used as fingerprint of a variety. Such biochemical markers can also discriminate the nucellar and zygotic seedlings in polyembryonic mango varieties. In order to validate the applicability of volatile as well as phenolic acid profiles as biomarkers, the open pollinated seedlings of three polyembryonic varieties of mango were compared with their mother trees. Leaf volatile and phenol acid profiling were done using Gas Chromatography/Mass Spectrometry (GCMS) and Liquid Chromatography/Mass Spectrometry (LCMS) methods respectively. The sesquiterpene hydrocarbons were the most abundant in all the genotypes studied. Monoterpenoids were the major compounds in cultivars Vellaikolumban and Olour, while the sesquiterpenoids were the major compounds in cv. Turpentine. While terpinolene was the major monoterpenoid compound in Vellaikolumban and limonene in cv. Olour, the sesquiterpene á-gurjunene was the major compound in cv. Turpentine. Volatile profiling showed clear differences between the varieties but was similar within a variety. Among the 15 phenolic acids quantified in the leaves, P-coumaric acid, gallic acid, and ferulic acids were predominant whereas, vanillic acid, syringic acid, gentisic acid, benzoic acid, and sinapic acids were low in quantity. Phenolic acid profile did not show significant diversity among the varieties and therefore cannot be used for identification of varieties. The volatile profiling can be used for the identification and differentiation of polyembryonic mango genotypes.

The study was undertaken for two consecutive years (2017 and 2018) to evaluate the effect of different growth media on various growing parameters and incidence of insect pest on brinjal and chilli seedlings. Seedlings were grown in protray using six types of growing media. The highest germination percentage (71.11), plant height (11.05 cm), number of leaves (5.81) and percentage healthy seedlings (89.82) were observed with vermiculite + perlite + vermi- compost (1:1:2) during both the years in brinjal. Similarly in chilli, highest germination percentage (66.33), plant height (9.81 cm), number of leaves (5.62) and percentage healthy seedlings (87.61) were observed with vermiculite + perlite + vermi-compost (1:1:2). There was significantly low incidence of whitefly in brinjal (1.49 whitefly/leaf) and chilli (1.65 whitefly/ leaf) seedling grown in media with vermiculite + perlite + vermi-compost (1:1:2). Hence, vermiculite + perlite + vermi-compost (1:1:2) was found as optimum growth media for growing of chilli and brinjal seedlings. The findings of this study recommend the use of vermiculite + perlite + vermi-compost (1:1:2) as growth media for raising nursery by farmers as it had significant positively effect on plant growth parameters of seedlings that lead to increase production of chilli and brinjal.

Nutrition and planting geometry are the two key factors affecting the production and quality of cut stems in chrysanthemum. The present investigation was undertaken to standardize the nitrogen nutrition and planting geometry for chrysanthemum var. “Yellow Star” cultivated for cut flowers. The data revealed the proportionate increase in plant height, chlorophyll content, days to bud appearance and days to 50% inflorescence anthesis and length of cut stem with increase in nitrogen dose and row spacing. However, flower diameter, number of flowers per stem, cut stem diameter, vase life, and water absorbed by cut flower decreased proportionately with increase in nitrogen dose and row spacing. Application of N@100 Kg ha-1 to chrysanthemum planted at 20x10 cm spacing produced cut stems of acceptable length, more number of flowers of bigger size and optimum postharvest longevity. The amount of nitrogen can be reduced to 1/3rd to grow cut chrysanthemums planted at twice the row spacing for longer cut stems of appreciable vase life.
营养和种植形态是影响菊花切茎产量和品质的两个关键因素。为规范菊花切花品种“黄星”的氮素营养和种植形态，进行了调查。结果表明，随着施氮量和行距的增加，植株高度、叶绿素含量、到出芽天数、到50%花序开花天数和切茎长度均成比例增加。但随着施氮量和行距的增加，花径、单茎花数、切茎直径、花瓶寿命和切花吸水率均成比例降低。应用N@100 Kg ha-1，种植间距为20 × 10 cm的菊花，茎段长度可接受，花的数量更多，大小更大，采后寿命最佳。氮素用量可以减少到三分之一，以两倍的行距种植切花菊花，以获得较长的切花茎，并有可观的花瓶寿命。

The present investigation was undertaken to standardize the nitrogen nutrition and planting geometry for chrysanthemum var. “Yellow Star” cultivated for cut flowers. The data revealed the proportionate increase in plant height, chlorophyll content, days to bud appearance and days to 50% inflorescence anthesis and length of cut stem with increase in nitrogen dose and row spacing. However, flower diameter, number of flowers per stem, cut stem diameter, vase life, and water absorbed by cut flower decreased proportionately with increase in nitrogen dose and row spacing. Application of N@100 Kg ha-1 to chrysanthemum planted at 20x10 cm spacing produced cut stems of acceptable length, more number of flowers of bigger size and optimum postharvest longevity.
