Study of bicarbonate effects on some of physiological and growths parameters of 6 apple rootstocks
In this research, effects of calcium bicarbonate on some characteristics of M7, M9, M25, M26, MM106 and MM111 rootstocks using factorial experiment based on complete randomized block design with three replications was evaluated during 2012- 2013. Three level of calcium bicarbonate (0, 7.5 and 15 mM) were used on one year old M7,M9, M25,M26,MM106 and MM111 rootstocks grown in perlite: cocopite (1:1) medium. The results showed that the different levels of calcium bicarbonate had deferent effect on studied traits. Calcium bicarbonate, especially 15 mM reduced height, trunk diameter, dry and fresh matter weight, chlorophyll and carotenoid content of rootstock. But increased ion leakage, proline and carbohydrate content in apple vegetative rootstocks. In total, the traits measured showed that M9 and M26 rootstocks were tolerant and susceptible to the high calcium bicarbonate concentrations respectively.
