The chloroform phase was isolated into 7 phases by column chromatograpathy, and the bioassy showed that the 1 phase has strong inhibitory effect, was 91.01% on Abutilon theophrasti M., root length, 51.35%、63.93%on Echinochloa crusgalli L, seedling length and root length, and the Amaranthus retroflexux L.,germination rate is 0, the secondly was 2 phase and 5 phas, and next we continued iaolated these two phases.

用硅胶柱对氯仿组分进行分离得到7个组分，生物测定表明组分1化感作用最强，对苘麻根长抑制率为91.01%，对稗草芽长和根长的抑制率分别为51.35%、63.93%，反枝苋的发芽率为0；其次是组分2和组分5，由于组分2的含量相对较少，对组分1和组分5继续分离。

Three QTLs detected for maximum adventitious root length in solution culture, total root dry weight in both solution culture and paper culture accounted for about 20%, 23% and 13% of the total variations, respectively.

其中溶液培养中的最长不定根长、总根干重和旱作培养中的总根干重检测到的QTLs位点对总变异的贡献率分别为 2 0 %、2 3 %和 13 %左右；旱作培养中的最长不定根长、不定根数、根冠比和溶液培养中的根冠比仅检测到上位性位点，对表型变异的贡献率在 12 %～ 61%之间。

Root hairs of wild type were intensely induced in the presence of NAA, while the gls mutant was insensitive to NAA induced root hair initiation; Lateral roots of the wild type were dramatically decreased when treated with 2,4-D, while the gls mutant was insensitive to 2,4-D induced reduction in lateral root initiation; The seminal root length of wild type showed no obvious changes by the treatment with IAA, but the gls mutant was supersensitive to IAA with dramatic reduction in seminal root length, suggesting that the interactions of GLS gene with different hormones may involve different mechanisms.

外源NAA 处理强烈诱导野生型根毛发生，而gls突变体则不敏感；外源2，4-D处理，野生型侧根急剧减少，gls突变体则不敏感；外源IAA处理，野生型种子根长变化不明显，而gls突变体超敏，种子根长迅速变短，表明GLS基因与不同激素有不同的互作机制。

Excied root apex explants of seedlings from Mormodes Jumbo Odin × Catasetum expensum were induced to from PLBs in MS medium supplemented with BA (0.5 mg/l ). Histological observations confirmed that root cap were disorganized at early stage and followed by vascular strand of existing roots protruding into PLBs formation.

以不同时期的根类原球体为材料经石蜡切片后发现，早期会先在根尖端形成球状突出，随著根类原球体膨大，根培植体的维管束延伸到球体之中并支撑著尖端形成芽原基，而后根类原球体顶芽长出维管束成为植株。

Bioassay results revealed: compared with alcohol control, extracts at parameter 1, 4, 7 stimulated the absolute germination rate and potential, radicle growth, plumular axis growth, fresh weight, dry weight at different levels; extracts at parameter 2, 3 stimulated the all germination index except radicle growth and axis growth; extracts at parameter 6 stimulated all but radicle growth and fresh weight; extract at parameter 8 stimulated only the germination potential.

生物检测结果显示，与酒精对照相比：萃取参数1、4和7等条件苦楝叶提取物对杉木种子绝对发芽率、绝对发芽势、胚根长、胚轴长、鲜重和干重等发芽指标均表现出不同程度的促进作用，萃取参数2和3等条件苦楝叶提取对除胚根和胚轴外的各发芽指标起促进作用，萃取参数5条件苦楝叶提取物对除鲜重和干重外的各发芽指标起促进作用，萃取参数6条件苦楝叶提取物对除胚根和鲜重外的各发芽指标起促进作用，而萃取参数8条件苦楝叶提取物仅对绝对发芽势起促进作用。

Catarium that is naturally decomposed outdoors has an inhibitive effect on cabbage seed germination. While the inhibition effect increases with increase in extract concentration, it, however, decreases with decomposition time. With regards to the length of cabbage root, 0.1 g·mL-l aquatic extract of E. catarium inhibits root growth at every decomposition stage. With the exception of undecomposed E. catarium , other concentration extracts during decomposition enhances root growth. Aquatic extract from E. catarium also enhances cabbage stem growth.

滤纸培养皿试验结果表明：假臭草植株提取液对小白菜种子发芽的抑制作用随浓度增大而增大，且随植株分解时间的延长而逐渐减弱；就幼苗根长而言，不同分解时期0.1 g·mL-l的假臭草提取液对根长均表现为抑制作用，除未分解的假臭草以外，其他时期其他浓度的假臭草提取液对根系生长均有促进作用；假臭草提取液对小白菜茎长总体表现为促进作用。

Method］ 5 matrices: M1(50% peat + 50% perlite),M2(40% peat + 60% perlite),M3(50% peat + 50% chestnut soil),M4(40% peat + 60% chestnut soil) and M5(100% peat) used for Euonymus fortunei cutting in container were tested and the effect of the different matrices on the rate of callus induction and root growth,the length and number of root,and the growth amount of Euonymus fortunei was investigated.［Results］ The results showed that the best effect on Euonymus fortunei cutting was from the M1,in which,the rate of root growth,callus induction,the length of root and the number of new branch were 87%,88%,68.0 mm and 4.6 branches,respectively.

方法］ 采用5种基质配比，分别为M1（50%泥炭+50%珍珠岩）、M2（40%泥炭+60%珍珠岩）、M3（50%泥炭+50%栗钙土）、M4（40%泥炭+60%栗钙土）、M5（100%泥炭）对扶芳藤进行容器扦插育苗试验，对不同基质引起的扶芳藤愈伤率、生根率、根长、单株根系数目、新生枝数及新生枝生长量进行调查分析，［结果］结果表明，基质M1中扦插的扶芳藤生根率、愈伤率最高，分别为87%和88%；根长最长，为68.0 mm；平均新生枝数最多，为4.6条，效果最佳。
