Fig. 1From: Comparative physiological and transcriptome analysis between potassium-deficiency tolerant and sensitive sweetpotato genotypes in response to potassium-deficiency stressDifferent sensitivity to K+ deficiency between K+-stress-tolerant sweetpotato cultivar Xu32 and K+-stress-sensitive sweetpotato cultivar NZ1.Phenotypes (A), dry weight (B), potassium content (C) and net K+ flux (D) of hydroponic-cultured sweetpotato seedlings under normal (Control) and K+-deficient conditions (-K) for two weeks. Date are means ± SE (n = 3). For (B) and (C), difference between mean values of -K and control were compared using t-tests (* P < 0.05)Back to article page
