Silicon (Si), as a beneficial or quasi-essential element, has different effects on physiological and biochemical processes in plants. But, many greenhouse growers in Iran, especially in soilless system (hydroponic), do not use Si in their recipe and fertilization program. This experiment was conducted to assess the effects of foliar application of different Si levels (0, 50, 100 and 150 mg/L) o...
With increasing frequency and intensity of dry spells in the cocoa production zones West Africa, strategies for mitigating impact water stress on seedling survival are urgently required. We investigated effects applied potassium biomass accumulation, physiological processes varieties subjected to pot experiments a gauzehouse facility. Four levels (0, 1, 2, or 3 g/plant as muriate potash) were u...
Abstract The selection of the appropriate almond cultivars (Prunus dulcis Mill.) in dry and semi-arid regions like Iran in order to produce the optimal product is the importance. In order to study tolerance to water deficit stress, One-year old plants five almond cultivars/ genotypes on the GN15, A factorial experiment was conducted with a RCD which included 3 irrigations factors, 5 genotype...
The turgor loss point (TLP), which is considered a threshold for many physiological processes, may be useful in plant-breeding programs or for the selection of reforestation species. Obtaining TLP through the standard pressure-volume (p-v) curve method in a large set of species is highly time-consuming and somewhat subjective. To solve this problem, we present an objective and a less time-consu...
abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...
Myrtle ) Myrtus communis L.) is a diploid plant belongs to the family of Myrtaceae and is considered as one of the important medicinal and ornamental plant. The present was performed to investigate the effect of salinity stress on morphological and physiological traits in myrtle. This study was conducted in an experiment of split plot in time according to a randomized complete block desig...
using plant growth regulators at the stresses environment can improve plant growth and crop production. hence, in this research response of photosynthesis rate, chlorophyll, soluble sugar and flower dry weight of chamomile to methyl jasmonate under different salinity levels was studied. values of 0 (control), 75, 150, 225 and 300μm methyl jasmonate (meja) with salinity levels of 2, 6, 10 and 14...
To quantify the effects of crown thinning on the water balance and growth of the stand and to analyze the ecophysiological modifications induced by canopy opening on individual tree water relations, we conducted a thinning experiment in a 43-year-old Quercus petraea stand by removing trees from the upper canopy level. Soil water content, rainfall interception, sap flow, leaf water potential and...
Water deficit, ultraviolet radiation and CO2 concentration enhancement are three environmental stresses that affect nutrition of human in future. This research was conducted in the Research Greenhouse of Faculty of Agriculture, Tarbiat Modares University in 2006, in order to study leaf qualitative traits of durum wheat under different levels of carbon dioxide (400 and 900 ppm), ultraviolet radi...
