plant performance and freshness is related to the pattern of its root growth development, which is highly affected by the water amount and water use management. therefore, the spatiotemporal variation of maize root under five treatments including full irrigation treatment (fi), partial root-zone drying treatments at two levels (receiving 75% of et =prd75, and 55% of et= prd55) and deficit irrig...
The investigation was carried out to determine of chemical composition and dry matter, neutral detergent fiber (NDF) and crude protein (CP) degradability parameters of Kahoorak (Prosopis stephaniana) by using nylon bag technique. Plant samples were taken from the Sar Chah Amari of Khoosf in Birjand city. Samples were collected at three stages of plant growth (vegetative, fruiting and seedi...
The present study evaluated the effect of nanochitosan in combination with plant growth promoting rhizobacteria (PGPR), PS2 and PS10 on maize growth. The PGPR were earlier recognized as Bacillus spp. on the basis of 16S rDNA sequencing. The observation revealed enhanced plant health parameters like seed germination (from 60 to 96.97%), plant height (1.5-fold increase), and leaf area (twofold). ...
Aluminum and silicon are usually abundant in the soil and most plants are affected by them. Therefore, in the present study, the effect of the interaction of Si (0 and 2 mM) and low concentrations of Al (0, 50, 100, and 150 µM) on some physiological parameters of Zea mays var. Merit were investigated and were analyzed by cluster heatmaps for better interpretation of results. Results showed that...
Field experiments were conducted during the 2010 and 2011 cropping seasons to investigate the effect of farmyard manure and weeding regimes on the growth and yield of okra. The study was a factorial experiment laid out in split plot design, replicated three times. Farm yard manure was assigned as main plot treatments, while weeding regimes was assigned as sub plot treatments. Parameters measure...
in order to investigate the effects of piriformospora indica and trichoderma tomentosum fungi on basil (ocimum basilicum l.) growth under copper nitrate levels, a pot experiment in factorial arrangement with three replicates was done during 2012. treatments were four levels of copper nitrate (0, 100, 200 and 300 mg kg-1 of soil) and four levels of fungal coexistence (non-inoculation control, in...
In this study, the effect of foliar spray of sodium nitroprusside (100 μM) as a nitric oxide donor on iron deficiency stress alleviation in cucumber plant was investigated. The results indicated that iron deficiency stress reduced growth parameters, total chlorophyll content, Fe content and antioxidant enzymes activity of catalase, ascorbate peroxidase as well as guaiacol peroxidase. Sodium nit...
This study was conducted in order to compare the hornwort aquatic plant (Ceratophyllum demersum) with an artificial filter for purification in a recirculating aquaculture system (RAS). At first, the fluctuation of nitrogen components of the water reuse system equipped with artificial filtration was evaluated. Experiments were performed during three months. The hornwort aquatic plant was collect...
Plant growth, pigment concentration, biochemical parameters and uptake of heavy metals were determined for Brassica juncea L. in response to cadmium and lead stress. The plant exhibited a decline in growth, chlorophyll content and carotenoids with Cd and Pb but Cd was found to be more detrimental than Pb treatment in B. juncea. The protein content was decreased by Cd (900 μM) to 95% and 44% by ...
increased nitrogen applications to crops influence plant-herbivore interactions and potentially increase herbivore population growth.in this research, the impact of nitrogen fertilizations on nutritional quality of three canola (brassica napus l.) cultivars (zarfam, okapi and modena), and, consequently, the performance of mustard aphids, lipaphis erysimi kalt., on them were investigated under g...
