长林系列油茶营养性状和繁殖性状对产量构成的影响
The influence of nutritional traits and reproductive traits on yield components in Changlin series Camellia oleifera
摘要
Abstract
To clarify the influence of leaf and flower morphological characteristics of Camellia oleifera varieties on their key economic traits,this study took Changlin No.4 and Changlin No.18 planted in Ji'an County,Jiangxi Province as the objects,systematically analyzed the relationship between leaf traits,flower characteristics and fruit traits as well as the yield per plant,and investigated the visiting insects.The results show that:(1)There are significant differences in leaf phenotypes and some flower characteristics between the two varieties;(2)In addition to the moisture content of leaves,the leaf phenotypes of the two varieties(including seven indicators such as fresh leaf weight,area,and thickness)were significantly positively correlated with fruit size(fruit length and width)and weight,which can be used for early yield prediction.(3)The coefficient of variation of fresh leaf weight of Changlin No.18 is significantly higher than that of Changlin No.4,and the floral characteristics are more complex,indicating that it has stronger phenotypic plasticity in response to environmental changes.(4)A total of 13 species of flower-visiting insects were found in the two types of C.oleifera,with the C.oleifera ground wasp and the curved horned mud wasp being the main flower-visiting insects.(5)The single fruit weight of Changlin No.4 is significantly higher than that of Changlin No.18,but its single plant yield is significantly lower than the latter.Comprehensive analysis indicates that Changlin No.18,with its higher leaf phenotypic plasticity and more diverse floral features,has more advantages in attracting pollinators and maintaining high yields.It is recommended to promote its cultivation in hilly and mountainous areas with significant environmental fluctuations.关键词
