‘V3’蝴蝶兰叶片性状与开花性状的相关性研究

The Correlation Between Leaf and Flowering Traits of Phalaenopsis Sogo Yukidian 'V3'

为了阐明蝴蝶兰叶片性状与开花性状之间的关系,建立一个通用外观质量鉴定标准。以未抽梗蝴蝶兰为试材,调查蝴蝶兰叶片的长、宽、厚、叶面积等叶片性状,然后对抽梗开花后的花朵数等6个花朵性状进行调查,并采用Excel 2017和SPSS 19.0等软件对其进行相关性分析。结果表明:‘V3’蝴蝶兰叶片性状与开花后花朵的性状品质具有高度的相关性。第一、第二、第三叶片长度与花朵直径具有显著的相关性关系,相关性系数分别达到0.552、0.236、0.167。第一、第二、第三叶片长度至少需要达到20.2、17.8、13.6 cm时,推测抽梗后花朵直径大于7.1 cm、花瓣厚度大于1.12 mm。即前3片成熟叶片长度较大者,可预期未来花朵数较多、花直径较大,具有较高品质的开花性状。利用这个简易的叶片性状,可以有效预测未来花朵的品质,为筛选植株幼苗提供一个简单易行的方法。

To elucidate the relationship between leaf and flowering characters,and establish a universal identification standard for appearance quality of Phalaenopsis Aphrodite,taking Phalaenopsis aphrodite without pedicels as test material,the length,width,thickness and leaf area of leaves were investigated,and then six flower characters such as the number of flowers after flowering were investigated.Correlation analysis was made by Excel 2017 and SPSS 19.0.The results showed that the leaf characters of Phalaenopsis Sogo Yukidian ‘V3'had a high correlation with flower characters after flowering.The length of the first,second, third leaf had a very significant correlation with flower diameter,the correlation coefficients was 0.552,0.236 and 0.167,respectively.It was predicted that the flower diameter was greater than 7.1 cm and the petal thickness was greater than 1.12 mm when the length of the first,second and third leaves was at least 20.2 cm, 17.8 cm and 13.6 cm,respectively.That is to say,the longer the first three mature leaves are,the more number of flowers become,the longer flower diameters become,so that the quality of flowering is higher.Using this simple leaf character,we can predict the flower quality effectively,and it is a simple and feasible method for screening plant seedling.
