Fig. 5From: Linking exogenous foliar application of glycine betaine and stomatal characteristics with salinity stress tolerance in cotton (Gossypium hirsutum L.) seedlingsEffect of foliar-applied GB on salt-stressed cotton seedlings GB content, proline content, soluble sugar content, and protein content are a, b, c and d 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)Back to article page
