bournei is present, its main regenerate type is by means of seed, the population age structure appears as “pyramid” pattern so that it enables the population to have a stable increase; sprouting is also the type of regeneration but is of weak capacity, with the net reproduction rate R o <1.
)Yang〕种群天然更新情况,结果表明:闽楠种群天然更新良好,种子繁殖更新是其天然更新的主要方式,种群年龄结构呈“金字塔”型,它能使闽楠种群稳定增长;也可通过萌蘖繁殖进行天然更新,但更新能力较弱,种群净生殖率Ro<1。
Experiment on 4 reproduction methods just as adult cutting, seed germination,sprouting and young cutting showed that under natural conditions, the former two method could not success; sprouting had higher sucess rate; young sprouting had possibility be successed, which also needed to be studied.
对南京椴采用硬枝扦插、种子常规发芽、萌蘖分株、嫩枝扦插4种繁殖方法进行探索,结果表明,在自然状态下,前两种方法不可能成功;萌蘖分株成功率较高;嫩枝扦插有成功可能,也是今后继续探索的方向。
For a quick method to controlling the soft sandstone areas,the author investigated the sprouting capacity of newly planted Hippophae rhamnoides forest in Zhungar township through the method of sample plot.

Experiment on vitro propagation of Daemonorops margaritae by sucker as explant showed that high concentration of 6BA and multiple hormones combination could promote cluster induction.
用萌蘖芽为外植体对黄藤进行组培快繁试验,结果表明,高浓度的6BA及多激素组合有利于丛芽诱导,但在继代增殖过程中需要适当降低6BA的浓度及除去2,4-D以利于芽伸长壮苗;0。
The result showed that suckering ability, mean length of mother stem and mean total length of the clump all increased with the age but decreased with planting density; suckering abilities among different density levels were different respectively at the 0.
结果表明:萌蘖力、藤丛的母茎长和总茎长均随年龄的增加而增大,随造林密度的增加而递减,密度的不同对6年和14年时的萌蘖力分别造成显著和极显著差异,而对植株母茎长无显著影响,但对14年时藤丛总茎长则有极显著影响;在14年时,林分自疏率随密度的增加而增加,不同密度水平间有极显著差异;林分直径大致随着密度的增加而递减,不同密度间有显著差异,但造林密度减小或增大至一定程度时对直径所产生效应并不明显;单丛产量随密度的增加而减少,受造林密度影响最大,除密度A与B及C与D间无显著差异外,其他密度间均达到显著或极显著差异;藤林总产量随着密度的增大先增加后逐步减少,不同密度间无显著差异,但以密度为3333株·hm-2时的总产量最高。
