Leaf physiological responses of the citrus commercial varieties grafted onto rootstocks

Abstract The use of rootstocks provides choices to growers increase fruit quality and yield, obtain high-density planting, avoid juvenility, control tree size. choice rootstock for a citrus orchard was an important consideration. aim the study evaluate effects on leaf mineral composition physiology commercial cultivars (‘ Pontianak ’ tangerine, ‘ Pamindo pamelo Montaji lemon). For this purpose, were budded onto Japansche citroen (JC) Citrumelo then (total nitrogen, phosphor kalium concentration) (chlorophyll index, respiration rate, stomatal conductance photosynthetic rate) each scion measured. Results showed that type had different influence in scion. total variables, no effect. variable, JC induced higher value than all chlorophyll Index lower but effect tangerine. rate tangerine ’. Therefore, better be , JC.
