对慈溪75株杨梅(Myrica rubra)雄株的雄花外观进行调查后,把雄花花序形状分为锥形、棒形、塔形、圆柱形4类,其中多数为锥形,占全部调查材料的62.7％,塔形和圆柱形分别仅有1份和2份；花序颜色可分为红、红黄、黄绿、玫瑰红4类,其中多数为红色,占全部调查材料的48.0％,玫瑰红仅有1份；花序长度0.8～3.8cm,多数2.0～2.9cm,占全部调查材料的64.0％；花序上着生小花数以20 ～ 29朵的为最多,占全部调查材料的82.6％；花粉量以锥形花序的为最多,圆柱形的次之,棒形的较少；雄花2月下旬苞片开裂,3月下旬至4月上旬出现盛花期,总花期长达35d左右.从所收集的资源中选取3份不同株系花粉分别在3个不同杨梅品种上进行人工授粉,结果表明人工授粉的座果率略低于自然授粉的座果率,用不同雄株的花粉座果率有差异.%The 75 androphytes inflorescence of Myrica rubra in Cixi were investigated for their morphological characters in Cixi, Zhejiang province. The results showed that the androphyte inflorescence emerged in late February, lasted until late March or early April, the total flowering time was about 35 days. The shape of the male inflorescence could be divided into four types: taper, club, tower, column, while the majority was taper (62.7%), the column and tower type had only one or two accessions. There weare four colors: red, red yellow, yellow green and rosy pink, about half of the investigated accessions awere red, only one rosy pink. The length of the inflorescence was in a range of 0.8 - 3.8 cm, most ranged from 2.0 to 2.9 cm (64.0% ). The flower numbers in each inflorescence awere most in a range of 20 - 29(82.6%).The taper inflorescence had largest amount of pollen, followed by the column, the club types. In addition, pollens collected from three accessions were tested on three different varieties of U. Rubra by artificial pollination, the results showed the percentage of fruit set by artificial pollination was slightly lower than natural pollination, difference among three pollen donor androphates was also observed.
