these results indicated that the increase of wue was mainly resulted from the reduction of leaf transpiration and flow rate of xylem sap in xylem vessels induced by si application.
表明叶片蒸腾速率、叶片导度、木质部汁液流速的降低是硅提高向日葵水分利用效率的主要原因。
in this paper, the transport characteristics of the nitrogenous com-pounds in the xylem sap of soybean plant were studied.
本文研究了大豆植株木质部汁液中氮素运输特征。
results showed that: (1) amount of xylem sap collected from trunk base of potted cuttings was half of that of ck;
结果表明:①切断主干基部所采集的树液量,盆栽树为对照树的一半。
similar trend was showed with the xylem sap aba, but no difference was observed in xylem aba in response to soil drying between different nitrogen treatments.
with the stress degree stronger and the stress time longer, the protein in xylem sap changed among 14.4~31kd for all alternative split-root osmotic stress.
daily and seasonal variability in the radial distribution of xylem sap flow velocity in trunks of pear trees were investigated by the heat pulse method.
