Aims We investigated aerenchyma formation in stems of riparian plants Arundinella anomala and Salix variegate as affected by addition of ethylene and a-naphthalene acetic acid under non-flooded conditions in order to ascertain whether phytohormone ethylene and auxin are direct stimuli for aerenchyma formation in flooded plants.

为了探究乙烯和α-萘乙酸是否是水淹环境条件下植物体内通气组织形成的直接原因，对三峡库区岸生植物野古草和秋华柳在无水淹环境条件下施加乙烯利和α-NAA后茎中通气组织的形成情况进行了研究。

In this experiment,we studied the effects of different medium on the bulblet formation,condition of growth and rooting.

针对不同培养基对百合苗增殖情况、长势及生根情况等方面进行了研究，结果表明，在高无机盐浓度并附加高浓度BA和低浓度NAA的培养基上适合百合苗的继代培养。

The results showed that NAA at low concentrations 0.1~0.2 mgL^(-1 was more beneficial for root induction, the rate of rooting was up to 100%. 1/4MS was more suitable to deal with the plantlet rooting and form small bulb. The optimal ratio of IBA and AC for rooting was 2.0 mgL^(-1) IBA+0.1%AC. The in vitro growth of plantlets were the strongest, and survival rate was 100% after incubating at 4℃ for 4 weeks when the diameter of bulblet was ≥9 mm.

结果显示；低浓度的NAA0.1~02mgL^(-1有利于根的诱导；生根率均达100%；大量元素1/4MS处理更适合试管苗的生根和小鳞茎形成；"IBA+AC"处理最佳组合是2.0mgL^(-1) IBA+0.1%AC；鳞茎直径≥9mm的试管苗去顶4℃低温冷藏4周；移栽后喷施1/2MS营养液；长势最好；成活率达到100%。

IAA was proved to be advantageous to producing more bulblets. The bulb scales treated by NAA could produce bigger bulblets. The propagation quotiety was inversely proportional with the bulblet volume.

吲哚乙酸有利于百合鳞片生成更多籽球，萘乙酸处理有利鳞片产生较大籽球，繁殖系数与繁殖的籽球体积成反比。

METHODS:The serum was added with VC as antioxidant and treated with ethyl acetate to extract rifampiein. The method employed C18 column,and CH3OH-0.025mol/L NaA c(adjust to pH 7.0 with HAc)as mobile phase,chlordiazepoxide as intra-standard,a nd the UV detection wave length was at 334nm.

血清加抗氧剂维生素C后，用乙酸乙酯提取浓集进样，采用C18柱(150×3.9mm 4μ)，以甲醇-0.025mol/L NaAc(用HAc调到pH 7.0)(62∶40)为流动相，氯氮( HT6"，5"K〗艹)/为内标，紫外检测波长为334nm。

With the corm and scale of A. albus in Zigui County in Hubei Province as tested material, MS was used as the basic medium with different hormones to respectively match 10 kinds of media for induction, differentiation for tissue culture of A. albus The induced clumpy buds were cut into single plants and were put into the rooting medium of MS+NAA 0.1-0.5 mg/L and the effects of different hormone matching on callus formation, bud differentiation and rooting were studied.

方法］以湖北省秭归县的花魔芋球茎和鳞片作为外植体，以MS培养基为基本培养基，添加不同激素，分别组配成10种诱导培养基和分化培养基进行组织培养，然后将诱导的魔芋丛芽切成单株后接入MS+NAA0.1~0.5 mg/L生根培养基，研究不同激素配比对愈伤组织形成和芽分化以及生根的影响。

Result The corm and scale were easy to induce the callus on the medium of MS+1. 0 mg/L 6-BA+1.0 mg/L NAA, with the induction of 92% and 90% resp. and the induced callus was easy to differentiate.

结果］球茎和鳞片在MS+6-BA1.0 mg/L+NAA1.0 mg/L培养基上容易诱导愈伤组织，诱导效率分别为92%和90%，且愈伤组织容易分化。

When the adventitious buds differentiated by corm and scale were transferred into the rooting medium of MS+0.5 mg/L NAA, the rooting reached to 94% and the whole plants were obtained after culture for 20 d.

将球茎和鳞片分化出的不定芽转至MS+NAA0.5 mg/L的培养基上，生根率可达94%，20 d后培养出完整植株。

Commonly used are NAA, indole acetic acid, such as cytokinin.

常用的有萘乙酸、吲哚乙酸、细胞分裂素等。
