摘要
植物抗盐性指标是研究植物抗盐机理和盐能力的基础,本试验利用营养土模拟土壤盐渍化的方式,研究了不同浓度NaCl处理对番茄生长发育的影响,以求为进一步研究盐胁迫条件下番茄生长发育和品质的调控提供理论依据.结果表明:0.04 mol/LNaCl、0.08 mol/L NaCl、0.16 mol/L NaCl 3 个盐胁迫处理均显著抑制番茄植株高度和茎粗的生长.在整个处理期间,NaCl盐浓度越大,对番茄植株高度生长的抑制越大.盐胁迫明显降低番茄的单株产量和单果重,随着NaCl盐浓度的增加,这种作用越强.盐胁迫对番茄单株产量的影响主要是单果重量减小造成的,而不是由番茄每株的果数造成.
Abstract
The index of plant salt resistance is the basis of studying the mechanism and ability of plant salt re-sistance.In this experiment,the effects of different concentrations of NaCl on the growth and development of tomato were studied by simulating soil salinization with nutrient soil,in order to provide theoretical basis for further study on the regulation of tomato growth and quality under salt stress.The results showed that 0.04 mol/L NaCl,0.08 mol/L NaCl and 0.16 mol/L NaCl significantly inhibited the growth of plant height and stem diameter.During the whole treatment period,the higher the concentration of NaCl,the greater the inhibition of tomato plant height growth.Salt stress significantly reduced the yield and fruit weight of tomato.With the increase of NaCl concentration,this effect became stronger.The effect of salt stress on the yield of tomato was mainly caused by the decrease of fruit weight,not by the number of fruit per plant.
