As regards rooting from clumpy buds, only NAA can induce rooting and NAA 0.5 mg/L is the best hormone concentration, whereas 6-BA has negative effect, and active carbon has no effect in this study.

猜A可使康乃馨愈伤组织分化，添加适量NAA效果更好，6-BA 1.0 mg/L＋NAA 0.5 mg/L和6-BA 2.0 mg/L＋NAA 0.5 mg/L诱导的芽点最多；但6-BA对丛生芽来源的无根苗的生根起抑制作用，活性炭对生根并无帮助，而以NAA 0.5 mg/L的生根效果最佳。

The root inducing medium, containing 0.5 mg/L NAA and MS medium with half of macroelement, gained 98% root inducing rate.

在大量元素减半的MS培养基中附加0.5 mg/L NAA进行生根培养，生根率达98%。

According to the root type division the Chinese Dwarf cherry belongs to the inductive type of root primitive body,From above several aspects we can see that the mechanism of soft-wood cutting is : Under the condition of without root primordium ,the root primordium appear from cambium by using rooting accelerator under the condition of well temperature ,humidity ,and light, then the root primordium breaks through the cerebral cortex, finally extends to outside .

从以上几个方面我们可以看出，欧李嫩枝扦插生根繁殖的机理为：欧李嫩枝在无根原体存在的情况下，经过生根剂的处理在合理的温度、湿度及光照条件下，由其形成层部位产生根原体，随后根原体突破皮层，伸向外部。

Our results showed it's very effective to antisepsis and rootage which added 600－fold chlorthalonil 75%wettable powder to rootone, and it can also enhance survival of carnation cuttage.

结果显示，600倍百菌清75％可湿性粉剂加入生根粉中，防腐和生根效果明显，具有提高香石竹扦插成活的作用。

An amount of 90% of shoots rooted on rooting medium, and 71% plants survived after transplanting.

在生根培养基中增殖的芽生根率高达90%，移栽成活率为71%。

The combinations of medium formula of perlite: vermiculite: turves=l:2:1 or 1:1:2 and 200 mg/L ABT rooting powder solution were in or near highest values on such indexes as surviving rate, rooting number, root length and seedling height, with their surviving rate being 97% and 98%, resp.

基质配方珍珠岩：蛭石：泥炭二l：2：1或1：1：2与200mg/L ABT生根粉溶液的组合在成活率、生根数、根长、苗高等指标上均处于或接近最高值，其成活率分别达到了97%、98%。

The combinations of medium formula of perlite: vermiculite :turves=1:2:1 or 1:1:2 and 200 mg/L ABT rooting powder solution were in or near highest values on such indexes as surviving rate, rooting number, root length and seedling height, with their surviving rate being 97 %and 98 %, resp.

基质配方珍珠岩：蛭石：泥炭越1：2：1或1：1：2与200 mg/LABT生根粉溶液的组合在成活率、生根数、根长、苗高等指标上均处于或接近最高值，其成活率分别达到了97 %、98 %。

Effects of ABT rooting powder No.1 (ABT1),α-Naphthaleneacetic acid and Indolebutyric acid on the rooting rates, biomass and taxol contents of Taxus chinensis var. mairei cuttings were studied in this experiment.

以清水处理为对照，使用不同激素(ABT1号生根粉、NAA、IBA)处理南方红豆杉插穗，从而研究不同激素处理对南方红豆杉扦插苗生根率、生物量及紫杉醇含量的影响。

The germination test of Sporocarps of Microlepia hancei prantl had been done, the callus can be induced from the delicate stem of Microlepia hancei prantl; The inducement and proliferation medium of callus was MS＋6-BA2 mg/L+NAA0.2 mg/L;the optimal combination of hormones of buds differentiation was MS+6-BA 0.4 mg/L; the effect of MS medium in radication culture was better than 1/2MS, the roots of plants were all efficiently induced in MS medium without reference to adding IBA、NAA or IBA＋NAA, the rate of radication was high; the effect of seedling cultured in the mixture of perlite and turf soil was better than perlite、garden soil and river sands.the mixture of perlite and turf soil has the excellences such as ventilate、water conservation 、nourishment and so on,the survival rate was higher and seedling substance was also hale.

试验进行了华南鳞盖蕨孢子果的萌发试验，并利用幼嫩茎段进行诱导愈伤组织；愈伤组织的诱导与增殖培养基为MS＋6-BA2 mg/L+NAA0.2 mg/L；其芽分化最佳激素组合为MS+6-BA 0.4 mg/L；生根培养中MS基本培养基比1/2MS效果好，MS基本培养基不论附加生长素IBA、NAA或IBA＋NAA，均能有效地诱导植株生根，生根率高；假植以珍珠岩和泥炭土的混合物为基质效果优于珍珠岩、菜园土和河沙，具有通气、保水、营养等优点，假植成活率高，苗势健壮。

The results showed that the rooting rate reached 83.2%~96.3% in 1/2 MS medium with IBA1.0~1.5 mg/L, The rooting rate of stem with top was significantly higher than that of stem without top; Snicking in stem base increased root number obviously, The appropriate substratum for transplanting was perlite and soil (1:1), The growth tendency of transplanting plantlets in May was slow-fast-slow.

结果表明：采用1/2MS培养基添加IBA1.0~1.5 mg/L，生根效果最好，平均生根率达83.2%~96.3%；带茎尖茎段的生根率显著高于不带茎尖茎段；茎段基部刻伤处理后较对照生根量明显增加；酸枣带根组培苗适宜的移栽基质为1：1的珍珠岩和土；5月份移栽下地的组培苗，其生长呈现慢-快-慢的趋势。
