effect of different citrus rootstocks on sweet lime (citrus limettiodes) leaf chlorophyll content and mineral element concentrations

the effect of four citrus rootstocks {sour orange (citrus aurantium), bakraeii (c. reticulata × c. limetta, mexican lime (c. aurantifolia) and volkamerlemon (c. volkameriana)} were evaluated on sweet lime leaf chlorophyll content and mineral concentrations (n, p, k, ca, na, mg, fe, zn, mn, cl, cu, and b) in a completely randomized design of four replications. budded sweet lime on the above rootstocks were grown in pots containing calcareous soil (ph=8.2) in a greenhouse expriment. results indicated that rootstocks had significant effects on the leaf chlorophyll content. highest chlorophyll content was found in lime leaf when budded on mexican lime rootstock. rootstock types had significant effects on leaf mineral concentrations except on b. leaf n concentration was lower than the optimum range inplants on all rootstocks. scion on sour orange rootstock contained the highest concentrations of both cl and na.
