二、遗传改良途径由于切花采后寿命遗传差异显著,因此进行长寿命切花品种的遗传改良是有可能的。1.常规选育常规选育首先要确定好切花的采后寿命评价对象与指标,如百合、唐营蒲等常以小花寿命为主要评价对象。确定的切花衰老指标不同,选育的效果也不同。前人研究表明,百合小花的衰老一方面表现为花瓣变形,另一方面表现为膨压丧失。对评估标准和评估温度进行方差分析显示,1
Second, the means of genetic improvement Since cut flowers post-harvest genetic differences in significant differences, so the long-life cut flowers varieties of genetic improvement is possible. 1. Conventional breeding conventional breeding First of all, to determine the cut flowers of post-harvest life assessment targets and indicators, such as lily, Tang Ying Pu and other flowers are often the main evaluation object. Determine the cut flowers of different aging indicators, the effect of breeding is also different. Previous studies have shown that, on the one hand, the floret lily aging performance petal deformation, on the other hand showed turgor loss. An analysis of variance on the assessment criteria and assessment of temperature showed that
