Fig. 7From: Impact of water deficit on the development and senescence of tomato roots grown under various soil textures of Shaanxi, ChinaSoil urease (µg NH+4 g−1 h−1), ß-glucosidase (µ pNP g−1 h−1) and alkaline phosphatase [(Alp) µpNP g−1 h−1] activity under soil water contents of 75–70% (CK) and 55–50% (D) in the soils of Hanzhong, Yulin, and Yangling in Shaanxi, China. Treatment values presented for comparison are the means of three replications (± SE, standard error). Means followed by different letters are significantly different (p ≤ 0.05) according to Tukey’s test. HA, Hanzhong; YU, Yulin; and YA, YanglingBack to article page
