本文报道华山松无性系嫁接种子园的36个无性系鉴定。经五年测定结果表明:不同无性系间在高、径生长量上的差异均达到1%的极显著。初步评选出7个优良无性系,其中有3个无性系高生长比群体平均数分别大23.4%、20%、18.3%,胸径生长量分别大21~33.8%。此外,华山松无性系间顶芽数、冠幅和胸径生长与高生长存在着密切的正相关(r=0.66~0.93),回归系数达1%的极显著。初步为华山松改良种子园的建立和表型早期选优提供了一定依据。

Three trials of Ginkgo biloba L. were established in Jiande Forest Farm in 1986 in order to determine the effects of age of rootstocks, grafting methods and clones of scions on grafting survival and shoot growth after grafting. An analysis of variance based on these trails indicated that the interaction of stock age X grafting method contributed significantly for Survival percent, the contribution of scion clones was very significant for 1-, 2-, and 3-year-old leader shoot growth. The correlations between shoot...

Three trials of Ginkgo biloba L. were established in Jiande Forest Farm in 1986 in order to determine the effects of age of rootstocks, grafting methods and clones of scions on grafting survival and shoot growth after grafting. An analysis of variance based on these trails indicated that the interaction of stock age X grafting method contributed significantly for Survival percent, the contribution of scion clones was very significant for 1-, 2-, and 3-year-old leader shoot growth. The correlations between shoot growth per year were strong, but it was weak between shoot growth and survival The authors concluded that the callusing ability and growth rate must be comtrolled by clones.

1986年在建德林场进行了三项银杏嫁接试验:①用采自1株雄树的接穗,分别在1~2龄和3~4龄苗砧上以切接、劈接、合接、腹接和插皮接5种方法嫁接,按裂区设计,重复3次,每小区接8株:②用采自60株雌树(无性系)的接穗以劈接法嫁接,按完全随机区组设计排列,3个区组,第1、2、3区组分别为8、9、10株小区;③用已嫁接成活生长1年的13个雌树无性系的嫁接苗,按完全随机区组设计进行栽培试验,5个区组,2株小区,株行距5×5m,年底测定嫁接成活率和各年度的新稍生长。数据分析表明:砧龄×接法的交互作用引起成活率的显著差异,1~2龄砧用劈接,3~4龄砧用合接最好。不同无性系间在嫁接成活率和1、2、3年新梢生长上都有极显著差异。各年度新梢生长具密切相关,它们与嫁接成活率的相关不紧密。认为愈合能力和生长速度都受到无性系的控制。

Lishui which linked with Zhangcun of Qingtian county, is one of the three key regions in Zhejiang province for oiltea camellia (Camellia oleifera) production with a name of "Oil Bank of Southern Zhejiang". Mixed varieties caused low and unsteady output, average output per mu was about 3 kg. Therefore, on basis of identification of oiltea camellia clones, 14 elite clones had been selected from 1983 for transforming low yield oiltea camellia forest by grafting in Nanshan Forest Region of Lishui Forestry Farm....

Lishui which linked with Zhangcun of Qingtian county, is one of the three key regions in Zhejiang province for oiltea camellia (Camellia oleifera) production with a name of "Oil Bank of Southern Zhejiang". Mixed varieties caused low and unsteady output, average output per mu was about 3 kg. Therefore, on basis of identification of oiltea camellia clones, 14 elite clones had been selected from 1983 for transforming low yield oiltea camellia forest by grafting in Nanshan Forest Region of Lishui Forestry Farm. 5 years observation abd analysis on output estimation of 2 year in succession showed that average output of oil per mu reached 6.6 kg, which was 104.7% of that in the control. It seemed that it is a good way to transform low yield forest by elite clones grafting for its easy method and big increase of output.

丽水是浙江省三个油茶基地重点县之一,与清田樟村相连成片,素有“浙南油库”之称。但目前油茶单产低而不稳,平均亩产茶油3公斤左右,主要原因是品种混杂。为此,我们于1983年,在油茶无性系鉴定的基础上,选出14个具有一定遗传增益的优良无性系,在丽水市林场南山林区进行了嫁接换种试验。经过5年观察和两年连续测产分析,平均亩产茶油6.6公斤,比对照高104.7%。初步看出,用优良无性系嫁接换种改造低产林方法简易,增产幅度大,是改造低产林的有效途径。
