The early (2-4 d) effects of slowly imposed soil water deficit on Lupinus albus photosynthetic performance, carbon metabolism, and hormonal balance in different organs (leaf blade, stem stele, stem cortex, and root) were evaluated on 23-d-old plants (growth chamber assay). Our work shows that several metabolic adjustments occurred prior to alteration of the plant water status, implying that wat...

The aim of this study was to analyze the effect of drought stress on the kinetics of leaf elongation in relationship to the variation of sugar concentrations and their net deposition rates along the elongation zone of leaf 4 of durum wheat plants. Plants were grown in soil in a naturally illuminated greenhouse, and water...

This work evaluated the effect of drought stress on seedling growth, protein, soluble sugars, and phenolic compounds of two cultivars of canola (RGS003 and Sarigol). Drought stress was induced with polyethylene glycol (PEG) at 0, 5, 10, and 15%. Drought stress increased root fresh weight in both cultivars and the effect of drought was more pronounced in RGS003. Shoot fresh weight reduced in Sar...

This study was conducted to determine the effect of compost and compost tea on growth and physiological parameters of Lepidium sativum L. 30-day-old Cress plants treated with compost and compost tea were harvested and different growth and physiological parameters were measured. Compost tea application increased RGR, SLA, ULR and RLAGR. The contents of Chlorophyll a and Chlorophyll b in the plan...

the aims of the study were to investigate the effect of poly(ε -caprolactone) (pcl) and nano- sio2 within the thermoplastic starch (tps) blends on the rate and extent of starch enzymatic hydrolysis using enzymes α-amylase and amyloglucosidase. the results of this study have revealed that blends with nano-sio2 content at 6 wt% exhibited a significantly reduced rate and extent of starch hydrolysi...

Basil (Ocimum basilicum) is a medicinal plant of the family of Lamiaceae. It contains phenylpropanoid and terpenoid componds. Chitosan with elicitor action induce defence mechanisms of plant. In the present study, the effect of chitosan on malondialdehyde (MDA), hydrogen peroxide (H2O2), gayacol peroxidase (GPX) , peroxidase (POD) and poly phenol oxidase (PPO) antioxidant enzymes activity, ph...

The metabolism of polysaccharides by pea stem segments treated with and without auxin was investigated using a centrifugation technique for removing solution from the free space of the cell wall. Glucose is the predominant sugar in both the ethanol-soluble and ethanol-insoluble fractions of the cell wall solution extracted with water. In the water-soluble, ethanol-insoluble polysaccharides, ara...

Drought stress is one of the most important factors limiting the survival and growth of plants in the different habitats of Iran. Detailed knowledge about the ecophysiological responses of native plants to drought stress could contribute to the success of breeding and re-vegetation programs. Six wild populations of Anthemis tinctoria, were assigned to four drought treatments, i.e. well...

introduction plant responses to environmental stress have a central role in agricultural production. responses results from events occurring at all levels of the organization, from biochemical reactions in cells to whole plant physiology. many plants are injured when exposed to low non-freezing temperatures. however, data on the effects of night temperatures are scarce. on the other hand, nitri...

Cotton (Gossypium hirsutum) flower’s showy corolla expands rapidly, then senesces quickly. Efficient opening of corollas is important for selfand cross-pollination, and indirectly lint yield. Carbohydrate relations are integral to bud water relations and growth, although they are not well understood. Soluble sugars and starch in developing floral buds and flowers of field-grown cotton plants we...
