Drought induced stress is one of the most significant environmental challenges. This study was designed to evaluate the effects of drought stress on crop yield and antioxidant systems during the vegetative period of wheat. The study was carried out in a greenhouse using factorial experiment based on complete randomized block design (RCBD) in three replications in Razi University in Iran from 20...

Two Þeld experiments were conducted in 1995Ð1996 to determine if there are common photosynthetic and vegetative growth responses among genotypes of maize, Zea mays L., to larval western corn rootworm, Diabrotica virgifera virgifera LeConte injury. SpeciÞc variables measured from rootworm infested and noninfested plants were midday leaf photosynthetic rate, plant growth stage, and plant height d...

the objective of the present study is to investigate the impact of spraying boric acid on vegetative and reproductive growth of ‘camarosa’ strawberry (fragaria × ananassa duch.). the strawberry plants were sprayed with boric acid at 0 (control), 50 and 100 mg l-1 at 30 days after planting. in general, results indicated that spraying plants with boric acid had a significant effect on yield, frui...

abstract growth retardants are new chemical organic compounds that increase period of flowering, leave chlorophyll, lateral shoot number, flower number and decrease vegetative growth. they also increase dry, cold and heat tolerance. paclobutrazol and cycocel are examples of these compounds. this study was conducted to evaluate the effect of paclobutrazol and cycocel on some quantitative and qua...

Drought affects the growth and development of rice from direct seeding or transplanting to maturity in northern China. It is important carry out QTL mapping for drought tolerance improve breeding. In this study, a RIL population consisting 253 families was constructed by crossing Miyang 23 with Jileng 1. The leaf rolling index (LRI), withering degree (LWD) chlorophyll content (LCC) were measure...

Vegetative cells and spores of five strains of Alicyclobacillus acidoterrestris (N-1100, N-1108, N-1096, SAC, and OS-CAJ) were screened for their sensitivity to high pressure homogenization (HPH, 0 to 300 MPa) in Bacillus acidoterrestris thermophilic broth. The most and least resistant strains, SAC and OS-CAJ, respectively, were further tested for their sensitivity to inactivation or growth inh...

Gene flow from genetically modified (GM) crops to wild relatives might affect the evolutionary dynamics of weedy populations and result in the persistence of escaped genes. To examine the effects of this gene flow, the growth of F1 hybrids that were formed by pollinating wild soybean (Glycine soja) with glyphosate-tolerant GM soybean (G. max) or its non-GM counterpart was examined in a greenhou...
