environmental stress especially drought is one of the most important factors to reduce and disturbance in different stages of floral growth especially sprouting in dry and semi-dry lands of iran. for this purpose a factorial essay executed in accidentally manner with four iterations in vitro condition. four genotypes of bromus tomentellus pasture types were used (92 tehran, 630 kordestan, 3414 ...

This research aimed at investigating the effect of different levels of nitrogen and planting patterns on dry matter production and growth physiological indices in intercropping maize and sunflower. To do this a split plot experiment carried out based randomized complete block design with three replications in research field of Shushtar Islamic Azad University. The main plot included three level...

stress management is considered as an important factor in nowadays landscape. therefore this research was conducted using a factorial experiment based on a randomized completely design with regulated deficit irrigation at four levels (100, 75, 50, and 25% of lawn irrigation requirement) and three replicates to evaluate some biochemical and physiological traits on four groundcover plants (lolium...

Comparisons of photosynthetic rates were made on leaves of ten species of woody dicotyledons grown in the field under full sun or under a canopy which transmitted approximately 18% of full light. Photosynthesis and dark respiration were measured and compared on various bases: area, chlorophyll, fresh weight of lamina, density thickness (fresh weight per unit area), and protein.Light-saturated p...

In this study, two isolates of genus Microdochium (W2 and B26) was isolated from the roots of healthy barley plants in agricultural fields from Kermanshah province in 2014 and were identified as Microdochium bolleyi based on morphological and molecular characteristics. Dual culture studies revealed that W2 and B26 inhibit 45% and 20% of the radial growth of Ggt in tur...

The objective of this study was to investigate the effect of pruning in different developmental stages on growth, development, seed yield and active substances of medicinal pumpkin (these active substances are uses for remedy the Benign Prostatic Hyperplasia (BPH)). The experiment was performed in a RCB design. Five pruning treatments in different developmental stages (no pruning, after 3-5 nod...

Hedysarum flexuosum L. is an important forage legume with high nutritive value. The determination of forage production in natural habitats is the most important factor for grazing management. Studies on its habitat characteristics and distribution are scarce. This research was conducted in order to evaluate the extent of pheno-morphological diversity in natural populations of Hedys...
