摘要
1986—1989年的研究表明,水涨龙眼结果母枝粗度与果穗生长关系最为密切,可作为衡量结果性能的主要生物学指标.提高结果母枝粗度可明显增加果穗重量,从而提高龙眼产量.当结果母枝粗度增加,果实数量相应增多时,其果穗会出现小果数增加的现象,应加强肥水供给.水涨龙眼优良结果母枝的生物学指标为:粗度0.60 cm 以上,长度8 cm 以上,复叶数5个以上.上述研究结果可为培养优良结果母枝提供重要依据.
Correlation between bearing basal shoots and bunch characters as well as biologi- cal indexes of Shuizhang longan were studied during 1986-1989 in south China.The four-year studies indicated that the diameter of bearing basal shoot exhibited close relation with bunch growth,which served as the major biological indexes to measure the fruiting po- tential.Increment in diameter of bearing basal shoot considerably increased the bunch weight and yield of longan.Number of abortive fruit on bunch increased as the diameter of bearing basal shoot increased.The biological indexes of fine bearing basal shoot of Shuizhang longan are:diameter,over 0.60 cm,length,over 8.00 cm and over 5 compound leaf.The final result of our research provided important basis of agrocomplex for fostering fine bearing basal shoot of Shuizhang longan.
