摘要
采用5个无患子果用优良单株无性系,在顺昌县营造区域试验林,通过对2年生各无性系的生长和开花结实性状调查测定和分析,结果表明:利用无患子果用优株无性系嫁接苗造林2年生植株开花株率达25.6%~34.9%,结实株率达16.6%~30.7%,平均单株产量0.26~0.54kg,最高单株产量达0.92~2.68kg;与采用一般实生苗造林7年生植株开花株率为22.7%且无结实相比,开花结实提早6年以上,具有明显的早实丰产效应;各无患子果用无性系间开花枝数、结果枝数及单株产量间存在显著差异,表明无患子果用优良无性系筛选的空间较大.
5 fruit--fine clones of Sapindus mukurossi were used to perform a test at a experimental forest in Shunchang County. Through the analysises of growth, blossom and fruit bearing characters of the biennial clones,the conclusion arrived. The results show that : the 2 years excellent clones grafted Sapindus rnukurossi has better characters than the 7 years seedling ones of 22.7% strain blossom rate,with 25.6%-34.9% of strains blossom rate, 16.6%~30.7% of strains fruit bearing rate and 0.26~0.54kg of average yield. The excellent clones have obvious effects of high yield and has a fruiting by 6 years earlier. Characters,like blossom--branch rate, fruit--branch rate and the yields differ among the strains of Sapindus rnukurossi, so there is still a larger space for fruit--Sapindus mukurossi screening in future.
