Pistachio is one of the most important commercial trees grown in Iran arid and semi-arid regions. Salt stress has been reported to cause an inhibition of growth and development, reduction in many plant characteristics. Adverse effects of salinity on growth, and characteristics of pistachio have demonstrated. Salicylic acid (SA) is known to have an affect on normal conditions and stresses in pla...

and any change in climate which alters the length of each phase is likely to alter the root shoot ratio, with effects on forest respiration and photosynthesis. Hence, we need accurate estimates of root and shoot growing periods to predict growth in a changing environment but most models of carbon and nitrogen allocation in trees do not take account of seasonal phases of growth (eg. Thornley, 19...

despite the importance of drought stress in early stage of growth and plant establishment, it has usually been neglected as selection criteria in breeding programs. therefore, a population of recombinant inbred line derived from the cross “babax/seri m82” and their two parents were studied. the experiment was conducted in two randomized complete block designs with two replications under osmotic...

An experiment was designed to determine the effect of the fungal endophyte Neotyphodium lolii on the growth, physiological parameters and mineral element content of perennial ryegrass (Lolium perennel L.), when growing at two N supply levels. Endophyte infection had a significant positive effect on both shoot and root growth of ryegrass, but this difference was only significant in the high N su...

Plants continuously extend their root and shoot systems through the action of meristems at their growing tips. By regulating which meristems are active, plants adjust their body plans to suit local environmental conditions. The transport network of the phytohormone auxin has been proposed to mediate this systemic growth coordination, due to its self-organising, environmentally sensitive propert...

An efficient protocol was established for rapid in vitro propagation of Stevia rebaudiana Bertoni, using explants from mature plants. The effect of 1/2MS, MS and B5 culture media, also 27 different combinations of auxins and cytokinins was studied on in vitro growth and development of Stevia rebaudiana Bertoni. The best culture medium for shoot and root formation was 1/2MS, producing 1.30 shoot...

to evaluate the sensitivity of different crops included some pulses to simulated metribuzin soil residues, an experiment was conducted in completely randomized design with factorial arrangement and four replications in research greenhouse of college of agriculture, ferdowsi university of mashhad. treatments included of 8 crops (chickpea, common bean, lentil, corn, wheat, barley, rape seed and s...
