A pot experiment was conducted during 2014 and 2015 seasons in completely randomized factorial design to determine the effect of natural extracts foliar spray of Moringa leaves extract (1:30), humic acid (10%), seaweed (2%), Hogland nutrient solution and tap water as control on growth characteristics (plant height, stem diameter, number of leaves/plant, number of branches/plant, root length, and total dry weight of plant parts (roots, shoots and flowers), floral and chemical characteristics of Lagerstroemia indica grown at various sea salt concentrations (0, 3.12, 6.25 and, 9.37 dS/m) showed that by increasing sea salt concentrations, all growth characteristics, inflorescence number/plant and, inflorescence diameter decreased significantly, while, the number of days to inflorescence increased. Total chlorophylls, carotenoid contents, total carbohydrates and N, P, K%. Meanwhile, proline content, total soluble phenols, Na, Ca, and antioxidant enzymes (catalase, superoxide dismutase and peroxidase) increased at the high level of salinity (9.37 dS/m). The usage of the Moringa leaf extract was significantly improved growth, inflorescence, as well as chemical characteristics, but also, decreased significantly Na under the adverse conditions of the studied sea salt stress. Moringa leaf extract could promote and protect crape myrtle plants against injuries by sea salt stress can substitute inorganic or chemical fertilizer being safe and cheap.

Yellow vine (YV) on cranberry (Vaccinium macrocarpon Ait.) is a symptom of stress that might reduce upright net photosynthetic carbon assimilation (A) through both, stomatal effects, which reduce the internal CO2 concentration (Ci), and nonstomatal factors. This study evaluated the shade effects on reversing the effects of YV symptoms in chlorophyll and nutrient content, and uprights gas exchange. Shaded vines were affected in the same way as unshaded yellow vines and their net photosynthetic carbon assimilation was not affected by stomatal activity in contrast with the normal green vines. However, A was not limited by stomatal activity ≥ 250 mmol m-2 s-1. Chlorophyll a concentration was positively correlated with A (r = 0.53 P≤ 0.05), shaded and YV had significantly lower total chlorophyll concentration relative to normal vines. Chlorophyll b was less affected by YV symptoms. Plant tissue were collected in autumn and analyzed for individual nutrient composition. Manganese levels were excessive in all samples; this was especially true for yellow vines, suggesting that the yellow vines may be under more water stress. Shading yellow vines did not change their nutrient composition relative to unshaded yellow vines. It is plausible that excess water on the bog is the major cause of the yellow vine as growers have a cultural practice of applying 25 mm of irrigation water a week regardless of the evaporative demand or field capacity.

A screening technique for the identification of resistant germplasm of apple (Malus spp.) and pear (Pyrus spp.) to white root rot (Dematophora necatrix Hartig) was standardized under field conditions. Rooted suckers were planted in the field during late dormancy stage (February). These were challenge inoculated when plants had established in the field and attained new growth (during the month of July) by introducing fungus inoculum multiplied on wheat grain in the rhizosphere (50 grains/ sucker). Soil moisture was maintained at the field capacity. Different species exhibited differential reaction to disease development parameters viz., mycelial colonization of the infected plant parts, rate of wilting, defoliation, necrosis on the bark, wood and vascular region. Necrosis on the leaves was observed as first symptom of disease expression which took 10 days after the inoculation in susceptible species whereas incubation period was extended in resistant species. Most of the population of different susceptible host species collapsed within 30 days of inoculation. The mortality rate varied with species. The technique evolved is easy, quick, reliable and capable of creating required disease pressure under field conditions for screening rootstocks against white root rot disease.

The experiment was conducted to study drying kinetics of ultrasound assisted, microwave drying of okra and its effect on colour change, texture and rehydration properties of okra. The samples were dried in a continuous microwave dryer at 540 W power level and at a belt speed of 5 mm s-1. It was observed that ultrasound as pre-treatment led to significant reduction in drying time of okra. Page model was found to be the best to explain the drying behaviour of okra with high R2, lowest RMSE and X2. Ultrasound retained the colour properties of okra. The lowest total colour difference was recorded in ultrasound treated60 minutes sample (18.11) followed by the control dried sample (17.58). The textural properties of the treatments of ultrasound treated – 60 minutes and ultrasound treated-vacuum packed -30 minutes samples had the values of hardness, gumminess and chewiness closer to fresh okra values. The highest coefficient of rehydration was recorded in ultrasound treated60 minutes samples. The vacuum pack did not show any effect on the rehydration ratio. The rehydration ratio increased with increase in time from 30 to 60 minutes. Key word: Ultrasound pre-treatment, microwave drying, okra, vacuum packing
研究了超声辅助微波干燥秋葵的干燥动力学及其对秋葵色泽变化、质地和复水性能的影响。样品在540 W功率的连续微波干燥机中以5 mm s-1的带速干燥。结果表明，超声预处理能显著缩短秋葵干燥时间。Page模型具有较高的R2、最低的RMSE和X2，可以较好地解释秋葵的干燥行为。超声波保留了秋葵的颜色特性。超声处理60分钟样品的总色差最低(18.11)，其次是对照干燥样品(17.58)。超声处理- 60分钟和超声真空包装-30分钟样品的硬度、胶度和嚼劲值更接近新鲜秋葵的值。超声处理60分钟的样品复水系数最高。真空包装对补液率没有任何影响。从30 ~ 60分钟，补液率随时间的增加而增加。关键词:超声预处理，微波干燥，秋葵，真空包装

Polyamines and boron spray were applied on gerbera to study their effect on the quality of flowers in potted plants of gerbera cv. ‘‘Kosak’’. The experiment was laid out in completely randomized design with six treatments (control, 0.8 mL-1 boron, 2 mMol L-1 putrescine (Put), 2 mMol L-1 spermine (Spm), 0.8 mL-1 boron + 2 mMol L-1 Put and 0.8 mL-1 boron + 2 mMol L-1 Spm) replicated six times. Gerberas (ligules and leaves) cv. ‘‘Kosak’’ were sprayed once with 100 mL of each concentration as treatment. In all the treatments, 1 mL/100 L-1 of a non-ionic surfactant was added to improve wetting and spray distribution. The results indicated significant effect of Put, Spm and boron on measured traits (P≤0.05). Mean comparison showed that 2 mMol L-1 Spm produced the better quality potted gerberas. It was verified that polyamines and boron was effective to delay flower senescence of gerberas ‘‘Kosak’’. However, the combination of the two substances (0.8 mL-1 boron + 2 mMol L-1 Put and 0.8 mL-1 boron + 2 mMol L-1 Spm) had non significant effect on flower shelf life.

Demand for fresh vegetables has led to development of postharvest teconologies mainly focused on minimizing the use of chemical additives and look alternatives for food preservation. The use of naturally derived edible coatings emerges as a promising alternative for maintaining quality and safety of horticultural products during storage. The objective of this study was to evaluate the use of Aloe vera gel for edible coating in green beans (Phaseolus vulgaris L.) to extend postharvest life. Treatments were: immersion 1:1 (50%); 1:3 (25%) with Aloe or distillated water (0:1) for 5 minutes at room temperature. Overall visual quality, weight loss, color, firmness, total soluble solids and at the end of storage period microbiological evaluation and electrolyte leakage were measured over 14 days of refrigerated storage at 5 or 10 oC. Results were analyzed by Tukey test and non parametric method was used for visual quality. All samples stored at 5 oC, regardless of Aloe gel dose, had higher visual quality, lowest weight loss and better color retention than those stored at 10 oC. Electrolyte leakage was higher in non treated product. Soluble content was higher and weight loss lower in treated samples.

Various nutrient interventions affect onion yield and storage quality. Integrated nutrient management interventions need be evaluated for their effect on yield of rabi onion. Three farmyard manure (FYM) rates (0, 25 and 50 t ha-1), three nitrogen (N) rates (75,100 and 125 kg N ha-1), three P rates (30, 50 and 70 kg P2O5 ha -1) and three K rates (30, 50 and 70 kg K2O ha -1) were tested on Punjab Naroya cultivar by using Latin Square Design. A control plot was kept with each rate of FYM application. The treatments were replicated over three artificially created fertility strips. Fertilizer N was the most limiting element. Higher FYM rates though can be used to reduce N, P, and K fertilizer rates, but doubling FYM rate from 25 to 50 t ha-1 did not benefit in general. Bulb yield data indicated that 25 t ha-1 FYM, 100 kg N ha-1, 50 kg of P and K ha-1gave the best results. The results hold significance in view of higher FYM rate recommendation (50 t ha-1) in certain states.
不同的营养干预对洋葱产量和贮藏品质有影响。综合营养管理干预措施对萝卜葱产量的影响有待评价。采用拉丁方设计对旁遮普纳罗亚品种进行了3种农家肥(0、25和50 t hm -1)、3种氮肥(75、100和125 kg N -1)、3种磷肥(30、50和70 kg P2O5 ha-1)和3种钾肥(30、50和70 kg K2O ha-1)的试验。每个施用率保留一个对照小区。这些治疗在三条人工制造的生育条上重复进行。氮肥是最大的限制因素。虽然较高的田间还田率可用于降低氮、磷和钾肥施用量，但一般而言，将田间还田率从25吨/公顷增加到50吨/公顷并没有好处。鳞茎产量数据表明，施用25 t hm -1、100 kg N hm -1、50 kg P和K hm -1效果最好。考虑到某些州更高的FYM率推荐值(50 t ha-1)，结果具有重要意义。

Phytochemical and molecular characterization of Piper species was investigated. There was a wide variation of the active compounds present in leaf and fruits of different Piper species/accessions. Among the two active compounds, piperine-1 content was more in P. chaba fruit and Piperine-2 in P. nigrum fruit as compared with other species. Inter Simple Sequence Repeats (ISSR) marker was also used to analyze the genetic variation between the species/accession of Piper species. The phylogenetic analysis generated by ISSR marker was divided into two major groups with 47% similarity. First major group is only one species (i.e., Piper spp. Accession -1) and also morphologically distinct from other seven species. The second group is divided into two minor groups. Piper betle var. Godi Balunga and Piper betle var. Astarangi Balunga are grouped together with 100 % similarity at genetic level, whereas, Piper betle var. Utkal Sudhama having 97 % similarity with Piper betle var. Godi Balunga and Piper betle var. Astarangi Balunga. Both phytochemical and molecular marker showed significant variation among and between species/accessions. This study will help for the breeding program in Piper.

Effect of 0.01M salicylic acid treatment on two rose plant cultivars (‘Red Berlin’ and ‘Red Horizon’) exposed to 0.2M NaCl or 0.35M D-Mannitol iso-osmotic stress (-1,05MPa) was studied. After five days of stress, the salicylic acid treatment strongly increased the proline content in leaves up to 28 times compared to control. It did not affect the soluble sugars content in ‘Red Berlin’, but decreased it below the control levels in ‘Red Horizon’. The plant response to salicylic acid application varied and was dependent upon the cultivar and the iso-osmotic agent. Thus, the salicylic acid had a beneficial effect on plants under NaCl stress and caused a slight increase in chlorophyll content and a significant increase in the quantum yield of photosystem PII in rose plants under Mannitol stress (Fv/Fm ratio about 0.72). It also increased leaf fresh/dry weight ratio of stressed plants (81% in ‘Red Berlin’), while it significantly reduced electrolyte leakage of stressed leaves.

Water deficit is one of the most adverse factors for plant growth and productivity. The experiments were conducted to investigate the influence of synthetic brassinolide analogue at concentrations 100 nmol L-1, 1 nmol L-1, 0.01 nmol L-1 and 0 nmol L-1 on lettuce seedling grown at two moisture levels (reduced, control). The plants were cultivated in growth chamber under day / night temperature of 20 °C/15 °C. The total quantities of irrigation water during the experiment: reduced – 28 mm; control – 39 mm. Brassinolide analogue were sprayed on the seedlings of two butter head lettuce cultivars (Mars and Maršálus) foliage at juvenile stage of growth. The plant parameters (length, fresh weight of shoots and roots) and dry matter content were measured on 21st and 28th day after sowing. Significantly higher values of the average fresh weight and length of above ground part and roots were recorded on 28th day for the cultivar Maršálus treated with brassinosteroide analogue at concentration 1 nmol L-1 in conditions with reduced irrigation. The results showed that treatment of plants at the initial stage of the development with 1 nmol L-1 solution can limit the consequences of reduced moisture conditions. Prior to use, the most effective concentration, plant parameter which is expected to be changed and sensitivity of the cultivars to the treatment, should be taken into account.
