摘要
研究了闽西武平县大沛梅百年实生群体的生态环境、生物学和栽培性状.结果表明,大沛梅在优越生态条件下,经长期的自然驯化与自身繁衍,已形成世代重叠的冲积地生态型实生梅群体,老树不衰,仍极丰产,平均株产147kg,最高株产275kg;结果以短果枝为主,占结果枝总数的53.5％,其次为针刺状短果枝和中果枝;完全花比例高,调查的10个单株均在74％以上;果实肉厚核小,可食率大都超过88％,达到国内果梅良种选育标准,具有较高的开发利用价值.对初选的10号和8号优良单株,调查了它们的生物学特性.并对开发利用大沛果梅的种质资源提出了若干建议.
Ecological environment and biological and pomological characteristics of natural population of plum, growing at Dapei on Wupin County in western Fujian for one hundred years were examinated. Dapei plum is one group of plants by long natural crossing and propagation, and being in a favourable ecological conditions. Average yield per plant of Dapei plum is 147 kg, the highest 275 kg. The most important fruit branch is fruit spur, accounting for 53.5% of the total. The next is spinding fruit branch, and then medium one. In 10 sirgle-plants examinated, complete flower all account for over 74%, and rate of edible fruit part mostly over 88%, amounting to the criterion of selective breeding for plum in our country, having the higher exploiting and useing value. Biological and pomological characteristics of excellant single-plants. No.10 and 8 were given on minute description and suggestion for further useing germplasm of Dapei plum is made.
