the anatomical and epidermal characteristics, as well as the physiological response, of 'colombia' ecotype cape gooseberry plants treated or untreated with foliar applications of kaolin at 2 irrigation levels (well-irrigated plants vs. water-stressed plants) were evaluated. relative water content (rwc), stomatal density, and chlorophyll index were reduced under water stress. water stress increa...

In this research, effect of drought stress on leaf characteristics was investigated in the experimental field of Miandoab Azad University, Iran using four facultative barley cultivars. Two separate experiments were conducted in pot and field conditions. In both experiments a factorial arrangement was used and the treatments were completely randomized in four replications. In each experiment ha...

Since the intvroduction (3) o,f the technique of beta gauging as a method for continuous and nondestructive mon!itoriing the water status of leaves, severcal reipo,rts (1-4) have appeared verifying the technique and its appl,ication in physio;logical research. Impliciit in this applicatiioni o?f beta gauging is the assutmption that, except for diurinal variations in water content, the physical ...

Establishing an accurate, fast, and operable method for diagnosing crop nutrition is very important for crop nutrient management. In this study, static scanning technology was used to collect images of a rice sample's fully expanded top three leaves and corresponding sheathes. From these images, 32 spectral and shape characteristic parameters were extracted using an RGB mean value function and ...

this study was carried out in order to determine the leave characteristics of some chestnut genotypes in the central black sea region of turkey and also to determine whether the leaf morphometric characteristics could be used for differentiation of genotypes. in this study, seven chestnut (castanea sativa mill.) genotypes (sa5-1, se 3-12, se 21-2, se 21-9, 552-8, 556-7 and 556-8) and one cultiv...

BACKGROUND AND AIMS The water-transport capacity of leaf venation is positively related to the leaf-lamina area, because the number and diameter of vein-xylem conduits are controlled to match the lamina area. This study aimed to investigate how this co-ordinated relationship between the leaf-lamina area and vein-xylem characteristics is achieved by examining the midrib xylem of tobacco leaves. ...
