Abstract

An experiment was conducted with three levels of salinity (0, 60, and 120 mM NaCl) and four levels of silicon (0, 5, 10, and 20 mM) in petridish. All the growth parameters were decreased gradually with increasing salt concentration, whereas increasing silicon concentration progressively increased the parameters up to 10 mM Si across all the salt concentrations. The beneficial role of Si was noticed both in saline and non-saline conditions. Silicon application in the growth medium dramatically reduced shoot Na content, making plants tolerant to salt stress.

盐胁迫条件下硅对玉米钠吸收的抑制作用促进玉米生长
实验采用3种盐度水平(0、60和120 mM NaCl)和4种硅含量水平(0、5、10和20 mM)的培养皿进行。随着盐浓度的增加,所有生长参数都逐渐降低,而随着硅浓度的增加,所有盐浓度下的生长参数都逐渐增加,直至10 mM Si。在盐水和非盐水条件下,Si的有益作用都得到了注意。在生长培养基中添加硅可显著降低植株茎部钠含量,使植株对盐胁迫具有耐性。科学通报,2011 (2);251-253: 2021年12月
