摘要:

为了研究不同类型盐对南瓜苗期生长发育的影响,利用240 mmol·L-1的强酸性盐磷酸二氢钠、弱酸性盐硫酸钾、中性盐氯化钠、弱碱性盐碳酸氢钠、强碱性盐碳酸钠对印度南瓜A70、中国南瓜A45、印中杂交南瓜7045进行苗期处理,考察其株高等农艺性状、叶片颜色及相对叶绿素含量。结果表明,南瓜对不同类型盐胁迫的耐受性存在显著差异,氯化钠影响最小,硫酸钾和碳酸氢钠影响相近,碳酸钠和磷酸二氢钠影响程度最大。不同类型盐对南瓜影响与pH值相关,可选择叶片颜色及茎粗作为南瓜砧木耐盐性评价的指标。

Abstract:

In order to study the effects of different types of salt on the growth and development of pumpkin seedlings, 240 mmol·L-1 strong acidic salt sodium dihydrogen phosphate, weak acidic salt potassium sulfate, neutral salt sodium chloride, weak alkaline salt sodium bicarbonate, strong alkaline salt sodium carbonate were used to treat Indian pumpkin A70, Chinese pumpkin A45, and Indian Chinese hybrid pumpkin 7045 during the seedling stages, and their plant height agronomic traits, leaf color, and relative chlorophyll content were investigated. The results showed that there were significant differences in the tolerance of pumpkins to different types of salt stress, with sodium chloride had the smallest impact, potassium sulfate and sodium bicarbonate had similar effects, and sodium carbonate and sodium dihydrogen phosphate had the greatest degree of impact. The effect of different types of salt on pumpkin is related to pH value. Leaf color and stem diameter can be selected as indicators for evaluating salt tolerance of pumpkin rootstocks.

Key words: acidic salt, alkaline salt, neutral salt, physiological acidic salt, pumpkin, leaf color, rootstocks
