4种授粉方法对切花百合不同杂交组合结籽量的影响

Influences on Seed Formation of Different Hybrid Combinations in Cut Flower Lilies by Four Pollination Techniques

以11种优质切花百合为试材,对两种发育时期的花采用常规柱头授粉、0.1%BA处理后授粉、花粉培养液(蔗糖100 g.L-1+H3BO320 mg.L-1+CaC l210 mg.L-1)处理后授粉、3%食盐水处理后授粉等方法,比较了不同授粉方法对杂交结籽的影响。结果表明:百合亲本组合、花发育时期对杂交结籽有很大影响;花粉培养液处理对杂交结籽普遍有促进作用,克服了1个亚洲百合杂交系内组合的杂交不亲和;食盐水和BA处理的作用不稳定,在有的亲本组合中表现为促进杂交结籽,在有的组合中表现为抑制作用。

In this experiment, 11 cultivars of cut flower lilies were employed as experimental materials to study the effects of pollination method on seed formation. Conventional pollination, pollination after the treatments of 0. 1% BA, pollen culture solution （sucrose 100 g ·L^-1 ＋ H3BO3 20 mg·L^-1 ＋ CaCl2 10 mg ·L^-1） , 3% salt solution were carried on in two different flower growth periods. Results showed that parental combination and flower growth period have a great effect on seed formation. Pollination after the treatment of pollen culture solution has considerable facilitation on seed formation, bypassed interspecific crossing barriers in a combination of Asiatic hybrids. Pollination after treatments of BA and salt solution can promote seed formation in some parental combination, but inhibit seed formation in others.
