反季节诱导荔枝雄性不育系MS1成花坐果初报
First Report of Off-season Induction of Litchi Male Sterile Line MS1 Flowering and Fruiting
摘要
Abstract
We have discovered and reported a litchi male sterile line MS1 recently but the characteristics of this male sterile was still unclear.In this study,grafted litchi male sterile line MS1 was used as the experimental materials and all the materials were planted in plastic pots.Anther fertility of the litchi male-sterile line MS1,characterized by off-season flowering,was assessed via morphological observation and paraffin sectioning.The results demonstrated that MS1 produced a low proportion of male flowers during high-temperature seasons.Moreover,both male and female flowers lacked viable pollen grains yet exhibited parthenocarpic ability.This study confirmed the stable male sterility of the MS1 line under high-temperature conditions,which lays the groundwork for determining its sterility type,and provides preliminary strategies for achieving off-season flowering in litchi.关键词
