In order to evaluate the effect of water deficit at different growth stages on yield and yield components of two cultivars of safflower, a study was conducted during 2009 and 2010 growing seasons at Research Farm of College of Agriculture, Shiraz University, Shiraz, Iran. The treatments were cultivar at two levels (Sina and Local Isfahan) as the main factor, irrigation regime at four levels (40...
background: satureja khuzistanica jamzad, with the common persian name “marzeh khuzestani”, is an endemic medicinal plant, distributed in the southwestern areas of iran. salicylic acid (sa) is a signaling molecule and a hormone-like substance that plays an important role in the plant physiological processes. objective: this study was conducted to determine the influence of foliar sa application...
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...
Mungbean (Vigna radiata (L.) Wilczek) or green gram as a dryland grain legume is exposed to varied timings and severity of drought stress, resulting in variability in photoassimilate production. In order to evaluate some physiological responses in one mungbean cultivar to timing and severity of drought stress, a 3-replicate RCBD (randomized complete block design) field experiment was carried ou...
Annual plants grow vegetatively at early developmental stages and then transition to the reproductive stage, followed by senescence in the same year. In contrast, after successive years of vegetative growth at early ages, woody perennial shoot meristems begin repeated transitions between vegetative and reproductive growth at sexual maturity. However, it is unknown how these repeated transitions...
Plant architecture is commonly defined by the adjacency of organs within the structure and their properties. Few studies consider the effect of endogenous temporal factors, namely phenological factors, on the establishment of plant architecture. This study hypothesized that, in addition to the effect of environmental factors, the observed plant architecture results from both endogenous structur...
Postembryonic shoot development in maize (Zea mays L.) is divided into a juvenile vegetative phase, an adult vegetative phase, and a reproductive phase that differ in the expression of many morphological traits. A reduction in the endogenous levels of bioactive gibberellins (GAs) conditioned by any one of the dwarf1, dwarf3, dwarf5, or anther ear1 mutations in maize delays the transition from j...
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...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
