| 摘 要： | 在组织培养条件下，对中国南瓜杂交种和黑籽南瓜的幼苗分别进行不同NaCl浓度(0、40、80、120、160、200、240 mmol/L)胁迫处理，10 d后调查不同处理单株幼苗的下胚轴长度、鲜质量、干质量和盐害程度。结果表明，360-3×112-2杂交种和黑籽南瓜在幼苗期存在明显的耐盐性差异，360-3×112-2杂交种耐盐性比黑籽南瓜强，360-3×112-2的最高耐盐浓度是160 mmol/L，黑籽南瓜的最高耐盐浓度是120 mmol/L，其耐盐性具有较大的利用价值。

| Abstract: | In vitro comparison of the salt tolerance of figleaf gourd(Cucurbita ficifolia Bouche.) and pumpkin hybrid(Cucurbita moschata Duch.) of 360-3×112-2 which showed stronger salt tolerance with previously selected experimental results, was made at the seedling stage exposed to a series of NaCl concentrations(0, 40, 80, 120, 160, 200 mmol/L). The growth characteristics of seedlings including hypocotyl length, fresh weight, dry weight, number of later roots and visual status were determined in 10 days after NaCl treatment. The results showed that significant difference in salt tolerance was exited between pumpkin hybrid of 360-3×112-2 and figleaf gourd, and the salt tolerance of the former was significantly higher than the later. It was suggested that 160 mmol/L and 120 mmol/L NaCl concentrations were the maximum stress values that pumpkin hybrid of 360-3×112-2 and figleaf gourd could tolerate respectively. Those results make hybrid of 360-3×112-2 available in breeding of salt-tolerant rootstock. |
