The biochemical and physiological evaluation of pear (Pyrus communis) cultivars, Carmen, Concorde, Red Bartlett and Packham’s
Triumph was done on Quince A, BA 29, Quince C and Kainth rootstocks at Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh, India during 2018-19. The highest leaf carbohydrate and starch content were reported in plants grafted on Quince C rootstock, whereas lowest on Quince A rootstock. Maximum total sugars and phenols were found in plants of Red Bartlett grafted on Quince C rootstock and minimum on Carmen grafted on Quince A. However, Carmen grafted on Quince A rootstock had highest total leaf chlorophyll content and uptake of nitrogen, phosphorus and potassium, whereas minimum on Red Bartlett grafted on Quince C rootstock. The correlation studies revealed a negative correlation among plant height, total sugars and phenols.
