peach (prunus persica l. batsch.) is produced in most areas of iran, where flowering is hindered by temperature. using plant growth regulators to delay bloom is a suggestive measure to avoid frost damage. the objective of this study was to determine the effects of methyl jasmonate (mj) and salicylic acid (sa) on peach bloom delay and yield.  this study evaluated the applications of mj 0 (contro...

 Peach has high nutritional value that can be used fresh-edible or processed. This study, the effect of different levels of methyl jasmonate (0, 100 and 200mgL-1) and salicylic acid (0, 1 and 2mM), and their interactions on increasing qualitative and antioxidant characteristics at harvest time of “Elberta” peach to be considered. Thus, trees sprayed by treatments in two stages ...

today, hormones and nutrients are used in order to improve vegetative and reproductive growth of many agricultural products in the world. the purpose of this study, was to increase fruit set, fruit weight, and finally, increase of yield along with improvement of vegetative growth with putrescine treatments (0, 0.01, 0.001m) and potassium nitrate (0, 2 and 4%) of quince (cydonia oblonga cv. esfa...

جو متحمل¬ترین گیاه به تنش شوری در بین غلات است و در گستره وسیعی از شرایط آب وهوایی قادر به رشد می¬باشد. گیاهان متحمل به شوری در انتقال سدیم در عرض تونوپلاست در شیب غلظت از سیتوپلاسم به واکوئل کارآمدتر هستند که این امر به گیاه امکان بقا و رشد را در غلظت¬های بالای شوری فراهم می¬کند. به منظور بررسی بیان ژن¬های خانواده hv tip (رمز کننده کانال¬های پروتئینی در طول غشاها، به ویژه در غشای واکوئلی) سه ر...

Current-activated tip-based sintering (CATS) is a novel process where spark plasma sintering conditions are applied through an electrically conducting tip on a locally controlled area on a green powder compact/bed. The localization of electric current in CATS allows for unique temporal and spatial current and temperature distributions within the tip and powder compact. In this paper, special ex...

The effect of the tip gap size on the performance of a multistage axial compressor was studied by means of computational fluid dynamics (CFD). It was found that the performance of the compressor was very sensitive to the size of the tip gap. By increasing the gap size, the stall margin value, the total pressure ratio and the compressor efficiency reduced considerably. The flow field at the tip ...

micropropagation is a proper approach to rapid and large-scale propagation of rootstocks and rose cultivars for huge demand of flower market. proliferation rate of shoot is decreased drastically following several subcultures. growth regulators have remarkable effects on the key phase of proliferation in micropropagation of this popular crop. in this research the effects of bap and antiauxin of ...

Root hairs provide a model system for the study of cell polarity. We examined the possibility that one or more members of the distinct plant subfamily of RHO monomeric GTPases, termed Rop, may function as molecular switches regulating root hair growth. Specific Rops are known to control polar growth in pollen tubes. Overexpressing Rop2 (Rop2 OX) resulted in a strong root hair phenotype, whereas...

The objective of this study was to investigate the effects of foliar applications of potassium and zinc on the fruit yield and quality as well as leaf nutrient concentrations of pistachio cv. ‘Chrokeh’. The experiment was conducted based on a completely randomized block design with nine treatments and three replications per treatment. Treatments were three levels of K2SO4 (0, 1 and 2%) and thre...
