摘要:
为明确三色堇和紫花地丁杂交种的生物学特性，对5种不同颜色的中花型单色花系三色堇及其与紫花地丁进行杂交育种，对母本三色堇及杂交种的生物学特性进行了较为系统的观察测量记录。结果表明：杂交种的株高、冠幅、花径均大于母本，表现出杂种优势。其中株高平均高于母本0.74 cm，冠幅5.34 cm，花径0.08 cm。杂交种的发芽率和结实率均普遍偏低，其中黄色单色花系三色堇的发芽率最低，只有16.30%。结实率最低为紫色单色花系三色堇与紫花地丁杂交组合，仅9.6%。杂交种的株高、冠幅、叶长、茎粗、花径及花葶长性状有利于特定环境下的定向诱导，而对叶宽和花数则不利。
Abstract:
In order to clarify the biological charactristics of Viola tricolor and Viola philippica hybrids,five species of Viola tricolor with different colors were crossed with Viola philippica,the biological characteristics of pansy and its hybrids were systematically observed and recorded.The results showed that the hybrid height,crown width and flower diameter were greater than the female parents,showing heterosis.Among them,the plant height was higher than the female parent 0.74 cm,crown 5.34 cm and flower diameter 0.08 cm.Hybrids,germination rate,seed setting rate were generally low,of which yellow monochrome flower Viola tricolor germination rate was the lowest,only 16.30%.The seed setting rate was the lowest,which was only 9.6% in purple monochromatic hybrids between Violoa tricolor and Viola philippica.The plant height,crown width,leaf length,stem diameter,flower diameter and long-flowered panicles of hybrids were conducive to the directional induction under specific environment,but unfavorable to leaf width and flower number.
