The limequat is a citrofortunella hybrid that is hybrid between the key lime and the kumquat. It has considerable amount of vitamin C acids which tastes similar to limes. Regarding these traits and it's relatively resistance to low temperatures. It can be a new commetrial citrus in thenorth of sour lemin trees in Mazandaran weather condition severely damaged by frost. Rootstocks had main affect on scion, such as vegetative vigority, tolerance to biotic and abiotic stresses, yields and fruit quality. The objective of this experiment was to evaluate of citrage, citromelo and sour orange rootstocks on the vegetative growth, tree size and mineral absorption ability of limquate. The experiment was conducted in a compeletly randomized design with seven replications. The results showed that the rootstock had significant effect on all parameters except the leaves numbers. The highest amount of chlorophyll (4.84 mg /100 gr) and plant stem diameter (7.07 mm) were observed on the citrange rootstocks plant. Limequats plants on sour orange (91 cm) and citrange (90 cm) rootstocks had vertical growth with better height but lime quat scion produced the most side branches on the citromello rootstock (5.8). The highest and the lowest percentage of water relative content were observed on sour orange rootstock (62.84%) and citrange rootstock (54.60%). In terms of nutrient absorption (nitrogen, phosphorus, potassium, calcium, iron, magnesium and manganese) significant effects were observerd between root stocks; the ability of citromello rootstock to absorb magnesium and manganese was less than other rootstock. In conclusion, citrange rootstock can be a suitable rootstock for Limequat in Mazandaran weather conditions.
