Leaf blade emergence rate (LER) was similar in the 6 and 9% HA (0.0095 leaves/degree day) being 26% higher than that observed in the 12% HA (Table 1).
Samples were cut in the cross-sectional direction in the middle third, border and central vein of the leaf blade, in addition to petiole section, made by free hand using Ranvier's microtome.
Both grass species differed (p<0.05) in stem diameter, leaf blade width and leaf blade length.
According to the analysis of variance summary (Table 1), the cationic composition of the irrigation water had significant effect (p < 0.01) on the percentage of cell membrane damage (%D), relative water content in the leaf blade (RWC), leaf succulence (SUC), plant height (PH), stem diameter (SD) and leaf area (LA) of the castor bean cv.
Relative to the leaf blade fraction, the values were higher for BRS Taruma genotype in all grazing cycles both in the initial and residual forage mass, confirming its prostrate growth habit and intense tillering (Martin et al., 2010).
The characters of leaf blade length, leaf blade width, fresh leaf weight, dried leaf weight, number of tillers, millable cane, bud size, cane diameter, number of internodes, internode length, plant height, stalk length, brix%, and individual cane weight showed high heritability except chlorophyll content (45.3%) (Table 2).

Twelve quantitative traitsfrom leaf(2),flower and seed(10) were selected.Principal component analysis (PCA) was done by XLSTAT.Fifteen fruit traits and four leaf traits were used to index mango morphology.The first three principal components clarified 34%of variation and identified fruit/stone traits especially the fruit length, fruit thickness and fruit width, fiber length, total soluble salts (TSS), leaf colour, twisting of leaf blade as important traits that could be used to categorize mango varieties.
Initial symptom was observed on any one leaf blade of plant characteristically as yellow to brown colored, drying of leaves started from margin (Figure 2 c).
