Effect of rootstock type on chlorophyll content and mineral elements concentration in scion of Kinnow mandarin

ABSTRACT: In this study was evaluated the effect of 4 citrus rootstocks consist Sour orange (Citrus aurantium L.), Bakraei (C. reticulata L.× C. aurantium L.), Mexican lime (C. aurantifolia L.) and Volkamer lemon (C. volkameriana L.) on chlorophyll content and mineral elements (N, P, K, Ca, Mg, Na, Fe, Zn, Cu, Mn, Cl and B) in scion’s leaf of Kinnow mandarin grown in pot containing calcareous soil in greenhouse as compeletly randomized design with 4 replications. Results showed that rootstocks had significant effects on leaf chlorophyll content. The greatest chlorophyll content obtained on Volkamer lemon rootstock. The rootstock types had significant effect on leaf mineral concentrations except of Cl, P, Cu, Mn and Zn. Leaf N and Mn concentration was lower than optimum range on all rootstocks, K on Mexican lime rootstock and Ca on all roostocks except Mexican lime. The scions on Sour orange had the highest Cl. Na concentrations was the heighest on Mexican lime rootstock.
