不同配方及浓度液体授粉对‘圣达尔’西瓜制种效果的影响

Effects of Liquid Pollination with Different Formulas and Concentrations on Seed Production of‘Sandal’Watermelon

我国每年需要大量西瓜杂交种子来满足生产的需要,因此,很有必要对西瓜杂交制种的过程进行研究。授粉是西瓜杂交制种过程中很关键的一个环节,本文以液体授粉对‘圣达尔’西瓜杂交制种为实验,以提高其制种产量和制种质量为为目的,筛选出了‘圣达尔’西瓜杂交制种中,适宜的液体授粉配方为:100mg/L硼酸+10%蔗糖溶液+2.5mg/L赤霉素,pH值等于7;适宜的花粉浓度为2g/L,为进一步增强制种生产效果提供依据。

China needs a large number of watermelon hybrid seeds every year to meet production needs.Therefore,it is necessary to study the process of watermelon hybrid seeds production.Pollination is a key part of the watermelon hybrid seed production process.In this paper,liquid pollination was used to test the hybrid production of‘Sheng Daer’watermelon,and the aim was to improve its seeds production yield and quality.In watermelon hybrid seed production,a suitable liquid pollination formula is:100mg/L boric acid+10%sucrose solution+2.5mg/L gibberellin,the pH value is equal to 7;the appropriate pollen concentration is 2g/L.Provide a basis for this production effect.
