During the process of long-time adaptive evolution, wetland plants adopted a series of special strategies to acclimate to salt stress. The main strategies are: 1 life history adjustment, e. g., to adjust seed germination time, implement seed dormancy and viviparity, and change reproductive manner to escape from direct salt stress, 2 morphological adjustment, e. g., to adjust biomass allocation pattern, age stem, defoliate, and carnify vegetative organs to isolate the redundant Na(superscript +) to the inactive-metabolism shoots or exclude the Na(superscript +)from tissues; 3 anatomic adjustment, e. g., to sink stoma, develop aerenchyma, and thicken cuticle and phellogen to maintain normal photosynthesis and respiration; 4 physiological and biochemical adjustment, e. g., to exclude and excrete salt, compartmentalize ions, adjust osmosis, do selective absorption, regulate hormones, and induce antioxidative enzymes to maintain the osmotic equilibrium and eliminate the active oxygen in cell; and 5 molecular level adjustment, e. g., to start up many salt-induced genes to regulate the metabolic responses to salt stress.

在长期的适应进化过程中，湿地植物形成了多种适应盐胁迫的策略，主要有：1生活史方面，植物可通过种子萌发时间的调整、种子体眠、胎生、繁殖方式的改变等逃避盐度的直接伤害；2形态学方面，植物可通过生物量分配模式的调整、茎的老化、落叶及营养器官的肉质化等将多余的Na隔离到代谢不活跃的茎中或将其排出体外；3解剖学方面，植物可通过气孔下陷、发达的通气组织、增加细胞木栓层、角质层及栅栏组织的厚度等以维持植物正常的光合作用和呼吸作用；4生理生化方面，植物可通过离子区隔化、拒盐、泌盐、选择性吸收、渗透调节、激素调节及抗氧化物酶的诱导等来维持细胞内正常的渗透压，清除胞内活性氧分子；5分子水平方面，植物可通过多种与盐胁迫相关的基因来调控细胞内的多种代谢反应。

The distribution of the qualitative characters The performance of the 39 chief qualitative characters were observed and recorded,according to the test method of morphological characters in the .The results of distribution proportion of each character in cultivars group showed that the distribution of 32 characters(number of ray flower rings,floret curliness,shape of leaf base,size of stipule and so on) were very asymmetrical with near or above 70%cultivars concentrated upon one or two performance, however,the distribution of the other 7 characters(floret type,surface color of outer floret,back color of outer floret,color of disc floret,claw in base of sinus between lateral lobes,stem erectness and stem color) in the cultivars group were relatively symmetrical.

质量性状分布参照《菊花DUS测试指南》的形态性状测试方法，观察记录大菊39个主要质量性状的表现，计算各性状的表现式样在品种群内的分布比例，结果显示舌状花的重瓣性、花瓣曲反状况、叶片基部性状、托叶大小等32个性状的表现式样在品种群内分布极不均匀，接近或超过70%的品种集中在性状的1种或2种表现式样中；而花瓣形状、外花瓣表面色、外花瓣背面色、花中心部颜色、叶裂刻基部有无突起、茎的曲直性和茎色等7个性状的表现式样在品种群内的分布则相对均匀。4。

Although their role in formation and deposition of cellulose microfibrils had been proposed, they may also performed a function in the lignification.

另外，在茎的部分基本薄壁组织细胞和韧皮部等未木质化的细胞壁中，过氧化物酶也同样表现出较强的活性，这说明在茎的不同组织中分布的这种酶，可能是几种不同功能的同工酶形式。

Result］ The extracted liquid from D. stramonium could decrease the germination rates of 4 vegetables and the seed germination of tomato and pepper. After treatment by 0.2, 0.4 g/ml extracted liquid , the seed germination of tomato and pepper were decreased by 10.2％, 9.4％ and 46.7％, 34.7％ than that of CK resp. The extracted liquid at 0.2 g/ml could inhibit the growth of vegetable root, but had some promotion on growth of vegetable stem. The extracted liquid at 0.4 g/ml had the strong inhibition on the growth of vegetable root, but its inhibition on growth of vegetable stem was greatly variable in different species.

结果］曼陀罗浸提液可降低4种蔬菜种子的发芽速率，降低番茄和辣椒种子的发芽率；0.2、0.4 g/ml曼陀罗浸提液处理后，番茄和辣椒种子的发芽率分别比对照降低了10.2％、9.4％和46.7％、34.7％。0.2 g/ml曼陀罗浸提液抑制蔬菜根的生长，而对茎的生长却表现出促进作用；0.4 g/ml曼陀罗浸提液对蔬菜根的生长有很强的抑制作用，对茎段生长的抑制作用因物种不同而有很大差异。

利用石蜡切片法研究了砂引草茎叶的解剖结构，尤其是对泌盐腺的位置、泌盐腺的形态结构及泌盐腺的发生发育过程进行了系统的研究，结果表明：砂引草茎的初生结构维管束是外韧的，且其有10-12束，大小不等，髓和髓射线发达；叶的上下表皮细胞各一层，栅栏组织与海绵组织分化明显。

The results showed aqueous shoot extracts of Euphorbia maculata could inhibit seed germination speed in all the four species, reduce seed germination rate in Lycopersicon esculentum, Schizonepeta tenuifolia and Capsicum frutescents, and its effects increased with the increase of extracts concentration, while having no effects on seed germination of Edible umaranth.

结果表明，斑地锦浸提液可降低四种蔬菜种子的发芽速率，抑制番茄、辣椒和荆芥的发芽率，并且这种抑制作用随处理浓度的提高而加强，而对苋菜种子的发芽率无显著影响；0.4 g/ml的斑地锦浸提液强烈抑制了四种蔬菜根的生长，却不同程度地促进了辣椒、荆芥和苋菜茎的生长，对根/茎比的影响与对种子发芽率的影响类似。
