Linking exogenous foliar application of glycine betaine and stomatal characteristics with salinity stress tolerance in cotton (

摘要

Effect of foliar-applied GB on salt-stressed cotton seedlings Pn, gs, Tr, Ci, Carboxylation efficiency (Pn/Ci) and WUE (Pn/gs) are a, b, c, d, e and f respectively. CK = control; T1 = 2.5 mM GB; T2 = 5 mM GB; T3 = 7.5 mM GB and T4 = 150 mM NaCl. Data are Mean ± standard deviation (n = 3). Different alphabets on top of error bars represent significant differences (p < 0.05)
