不同品种番茄幼苗在弱光条件下对亚适温的适应性研究
Study on Low Light and Suboptimal Temperature Adaptability of Seedlings of Different Tomato Varieties
摘要
Abstract
The effects of low light and suboptimal temperature on growth and physiological characteristics of tomato seedlings were studied with ten tomato varieties as experiment materials.The results showed that the growth,leaf chlorophyll content and root activity of tomato seedlings decreased;the electrolyte leakage,MDA content and proline content were different obviously between different vclrieties after treated for 14 days under low light and suboptimal temperature.The adaptability of 6#(Hongfen Champion)to suboptimal temperature under low light condition was superior to the others,so it was suitable for cultivation in solar greenhouse in winter of north China.The physiological reaction was similar to growth situation in plant.The growth incre-ment of seedlings,leaf electrolyte leakage,chlorophyll content,MDA content,proline content and root activi-ty could be used as the indicators for identifying the tolerance of tomato seedlings to poor light and suboptimal temperature.关键词
