Coriander Leaves

A study was conducted in the plains of Kerala to investigate the performance of coriander leaffor its quality aspects in open and rain shelter conditions. The study suggested that significantlyhigher herbage and biomass yield (g/ plant) was observed from plants grown in rain shelter(9.21 and 12.78) compared to the open field (8.41 and 11.34). Among the varieties, Arka Isharecorded the highest herbage and biomass yield (10.46 and 14.13g/plant) followed by CO-1(8.97and 12.70).There was a significant higher vitamin C content (mg/100g) in open field(189.72) compared to rain shelter ( 124.55) and volatile oil ranging from 0.05-0.06 % in boththe growing conditions and were on par. Total chlorophyll content was recorded more in openfield (1.98) than in rain shelter (1.92) Among the varieties, total chlorophyll was more in CO-4(2.33). However, this need to be confirmed by further studies.

This experiment was conducted at the plant tissue culture laboratory – Dept. of Horti.- Coll. of Agricultural Engineering Sciences – Univ. of Baghdad, in order to study the effect of magnetic field in the propagation and production of volatile oil compounds of rosemary plant Rosmarinus officinlis. Factorial experiments within completely randomized design with thirty replications were used. The results indicated  an increase in the treatment of exposure to south pole for 30 days with the highest mean of the shoots number, fresh and dry weight and total chlorophyll content (7.5 shoots.plant-1, 6634 mg, 769.5 mg and 160.6 mg.100 g-1) respectively. While the control treatment produced the lowest value of shoot number, fresh and dry weight and total chlorophyll content (5.7 shoots.plant-1, As shoots length, the exposure to south pole for 30 days, gave the shoot length (6 cm), while the exposure treatment to north pole for 20 days gave mean branch length of 2.25 cm. In terms of the effect of magnetic field on the concentration of volatile oil compounds, the results indicate that the exposure to south pole for 30 days significantly higher than the other treatments in the following compounds: linalool, Terpinene, linderol, Limonene cymene, and camphor penene. The 30-day north pole exposure was significantly higher in the two compounds: merycenen and sabinene.

The Relationship

The relationship between SPAD-501 meter readings (SPAD) and total chlorophyll content (TCHL) was evaluated for `Delicious' apple (Malus domestica Borkh.) leaves grown in various environments. Regression models were developed between SPAD and TCHL for each of six separate experiments and were evaluated for statistical coincidence. SPAD was linearly related in a positive manner to TCHL in five of the six experiments; however, models differed between experiments, particularly between field- and greenhouse-grown trees. Thus, the relationship between SPAD and TCHL must be determined for each experiment.

The Impact

Abstract Many of the world’s findings indicate the positive effect of earthworms on soil parameters, and consequently, on the formation of phytomass of cultivated plants. In our experiment we studied: A) the influence of soil itself, soil mixed with vermicompost in a ratio of 9:1; B) the influence of earthworms number (genus Eisenia foetida, 10 and 20 individuals per pot) supplied to soil mixed with vermicompost in the ratio of 9:1 on the dynamics of changes in the weight of radish roots, the total chlorophyll content in leaves and the selected qualitative parameters of the roots. The results obtained showed that one tenth proportion of vermicompost from the total weight of soil substrate caused the statistically significant increase in the total chlorophyll content in leaves, the increase in yield of radish roots, the reduction of the vitamin C content and the increase of nitrate content in the roots. The impact of earthworms on the chlorophyll content in leaves and on the root weight was negative. The addition of 10 individuals of earthworms into 20 kg of substrate (soil + vermicompost) resulted in the increased content of vitamin C and the decreased content of nitrates in the radish roots. Twenty earthworms added to vermicompost, compared to vermicompost alone, did not affect the vitamin C content and reduced the nitrate content.

Keeping Quality

Keeping quality and length of vase life are important factors for evaluation of cut flowers quality, for both domestic and export markets. Studding the effect of pre- and post-harvest salicylic acid applications on keeping quality and vase life of cut alstroemeria flowers during vase period is the approach taken. Aqueous solutions of salicylic acid at 0.0 (with distilled water), 1, 2 and 3 mM were sprayed to run-off (approximately 500 mL per plant), about two weeks before flowers harvest. The cut flowers were harvested in the early morning and both of cut flowers treated (sprayed) and untreated were kept in vase solutions containing salicylic acid at 0.0 (with distilled water), 1, 2 and 3 mM. Sucrose at 4% was added to all treatments as a base solution. The changes in relative fresh weight, water uptake, water loss, water balance, total chlorophyll content and vase life were estimated during vase period. The results showed that the relative fresh weight, water uptake, water balance, total chlorophyll content and vase life decreased significantly while the water loss increased significantly during experiment for all treatments. A significant difference between salicylic acid and control treatments in all measured parameters is observed. During vase period, the salicylic acid treatments maintained significantly a more favourable relative fresh weight, water uptake, water balance, total chlorophyll content and supressed significantly water loss, as compared to control treatment. Also, the results showed that the using salicylic acid increased significantly the vase life cut alstroemeria flowers, over control. The highest values of measured parameters were found when plants were treated by pre + post-harvest application of salicylic acid at 3 mM. The result revealed that the quality attributes and vase life of cut alstroemeria flowers were improved by the use of salicylic acid treatment.

Persian lime is economically important for Mexico. However, the disease known as Huanglongbing (HLB) causes chlorosis symptoms in the foliage that affect the growth and decreases the yield of the trees. The expression of chlorosis symptoms is associated with starch accumulation and inhibition of antioxidant activity. The objective of the present work was to determine the effect of the application of three resistance elicitors on the expression of three antioxidant genes and on starch and chlorophyll content in Persian lime trees with HLB. Salicylic acid (SA), jasmonic acid (JA) or gamma-aminobutyric acid (GABA) were applied every eight days for nine weeks using a completely randomized design and a one-way ANOVA was performed for the analysis. Expression of APX, CAT and SOD genes was quantified at week nine at four different times. Starch and total chlorophyll content was estimated every three weeks by spectrophotometric methods. The application of the elicitors significantly increased the expression of the three genes, with SA and GABA generating the greatest increase at different times of application. No difference was found in starch and total chlorophyll content at most of the times evaluated. The use of resistance elicitors is promising in the management of HLB in plots already infected, seeking to extend the productive life of the orchards and thus counteract the economic losses caused by HLB.

Water spinach (Ipomoea reptans Poir) had been identified as a nutritious vegetable with high demand in Indonesia. Besides, this plant also has been evidenced to play an important role in environmental cleaning as phytoremediator. The study about the effect of organic fertilizers on the growth and yield of water spinach (Ipomoea reptans Poir) has been conducted in the Green House of Biology Department, Faculty of Mathematics and Natural Sciences, Universitas Negeri Medan. The study aims to investigate the most effective type of fertilizers and the dose for water spinach’s (Ipomoea reptans Poir) growth and yield. A Completely Randomized Factorial Design was designed for the experiment with two factors and three repetitions. The first factor is the type of fertilizer (chicken manure, cow manure, and compost), and the second factor is the dose of the fertilizer (1:1, 2:1, and 3:1). The parameters such as plant height, number of shoots, number of leaves, fresh weight, dry weight, leaf’s total chlorophyll content, and water content were measured to evaluate plant growth and yield. The General Linear Model used SPSS 21 programs was applied to analyze the collected data. Study results revealed that cow manure increased plant growth and yield significantly with dose 2:1 as the finest treatment, followed by dose 3:1. Cow manure also increased total chlorophyll content (8.0574c mg. L-1), with the most suitable dose was 2:1 (8.2807 mg. L-1). The plant’s water content tended to be high in chicken manure (93%), and the lower water content was in cow manure with dose 3:1 (87.5%).
