花生新品种泉花551高产特性研究

Study of high-yield characteristics of new peanut cv.‘Quanhua 551’

摘要: 以粤油551-116为对照品种，对泉花551的生育特性、光合特性、开花结荚习性等进行研究，探讨其高产特性，结果表明：泉花551开花量适中且集中在前期，有效花率和成针率高；叶片叶绿素含量高，叶面积指数大，净同化率高，尤其在中后期仍保持较高的经济系数。

Abstract: In this paper,growth characteristics,photosynthetic characteristics,flowering and pod bearing characteristics of peanut cv.‘Quanhua 551’ were studied with‘Yueyou 551-116’ as control.The result showed that flowering amount of‘Quanhua 551’ was moderate and was mostly flowering at the early stage.‘Quanhua 551’ showed high fertile flower rate and formed peg rate,high content of leaf chlorophyll,large leaf area index,high net assimilation rate and especially maintained high economic coefficient in the middle-late period.
