摘要：

土壤盐渍化是限制我国农业发展的主要原因之一,幼苗素质影响后期产量。为了探究盐胁迫对樱桃番茄幼苗生长的影响,该研究选择瓯秀红樱1号为材料,以3个梯度(50、100、150 mmol·L^-1)的NaCl溶液对其进行盐胁迫处理。研究结果表明,所有NaCl处理对樱桃番茄株高、茎粗、生物量有显著抑制作用,以150 mmol·L^-1 NaCl处理最为明显,其株高、茎粗和地上部生物量分别较对照下降了35.94%、12.80%和21.99%,而叶绿素相对含量(SPAD值)随NaCl浓度升高而升高。此外,与对照组相比,100和150 mmol·L^-1 NaCl处理均导致幼苗根尖丙二醛(MDA)含量及超氧化物歧化酶(SOD)、过氧化物酶(POD)活性升高。以上结果表明,NaCl处理对樱桃番茄的生长以及代谢具有明显的抑制作用。

Abstract:

Soil salinization is one of the main reasons limiting the development of agriculture in China. Seedling quality affects later yield. In order to investigate the effects of salt stress on the growth of cherry tomato seedlings, Ouxiuhongying 1 was selected as the material and subjected to salt stress treatment using NaCl solutions with three concentrations (50, 100, 150 mmol·L^-1). The results showed that all NaCl treatments had significantly inhibitory effects on plant height, stem diameter, and biomass of cherry tomato. Among them, 150 mmol·L^-1 NaCl showed the most significant inhibition, reducing plant height, stem diameter, and above ground biomass by 35.94%, 12.80% and 21.99%, respecctively, compared with the control group. The SPAD values increased with the increasing of NaCl concentration. Meanwhile, compared with the control group, the content of MDA, and the activities of SOD and POD in the root tips of cherry tomato seedlings increased under 100 and 150 mmol·L^-1 NaCl. All of these indicate that NaCl treatments have significantly inhibitory effects on the growth and metabolism of cherry tomato seedlings.
