In the, present study the relationship between cytokinin andcorn compensatory growth deserved much more attention. Underthe. Addition of NO3 − to roots and, after rewatering among the fourplant hormones ZR IAA GA3and ABA higher,,, leaf ZR concentrationwas. Observed in corn seedlings of the rewatering group comparedwith the wet treatment group. Moreover compensatory growthoccurred,, Simultaneously with increase in leaf ZR concentration.On, the contrary without the addition of NO3 − to roots no com-pensatory,, Growth occurred and no, high leaf ZR concentration wasfound upon rewatering treatment compared with wet treatment.Niu et. Al. (2009) and Luo et al. (2013) reported that rewateringafter drought stress increased the leaf cytokinin concentration. Inpea and cotton. In addition when exogenous, cytokinin was addedto leave the increased, ZR concentration in leaves led. To compen-satory growth after rewatering. Thus leaf cytokinin, was closelyrelated to compensatory growth upon post-drought. Rewatering.
