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。

Cone and seed development was observed from 1993 to 1998 in wind-pollinated Keteleeria davidlana Beissner var. formosana Hayata trees grown at Taipei Botanical Garden. Seed efficiencies per cone (percent filled seed per cone divided by seed potential) were persistently less than 1% during the investigation period.

Rapid nutrient accumulation as well as higher ABA content in seed coat and lower GA3/ABA ratio both in seed coat and embryo had significant effect on desiccation tolerance and shallow dormancy of mature Aesculus chinensis seeds during last stage of seed maturation.
种子成熟末期未经历明显的脱水过程,但此期间种子内营养物质的迅速积累以及种子脱落时种皮中较高的ABA含量、种皮和种胚中较低的GA_3/ABA值均对种子的耐脱水性和轻度休眠习性的形成起到重要的作用。

Temporally, rhizobium abundance in root and pericarp is obviously higher at pod-bearing stage than any other growth stage. Rhizobium abundance in various floral organs rapidly increases after pollination. During ovary-to-legume germinative process, rhizobium abundance in ovary wall and ovule increases logarithmically. Endogenous rhizobia are found in ovule only after fertilization, and rhizobium abundance in young seeds is higher than in fertilized ovule. This implies that endogenous rhizobia can be transported and colonized in early germinated seedlings.
在时间上,结荚期根、荚果皮内的根瘤菌数量明显高于其他时期;花内各器官在授粉后根瘤菌数量迅速增加;由子房向荚果发育的过程中,子房壁和胚珠内的根瘤菌数量随时间呈对数增长;胚珠在受精后即存在有内生根瘤菌,并且幼嫩种子内生根瘤菌数量远高于受精胚珠,证明内生根瘤菌能被转运并定殖在发育早期的种子中。

The results showed that O. fragrans seeds were desiccation-sensitive as the seed viability declined to 6% when the seed moisture content was reduced to 11.6%. The seed electrical conductivity increased with the declining moisture content, a sign, which was caused by increasing cell membrane cleavage. Superoxide dismutase activity decreased rapidly during desiccation; but peroxidase activity increased to the maximal value when dehydration for 12 h, then declined rapidly when seeds were dehydrated more than 12 h.
结果表明:'紫柄籽银桂'种子不耐脱水,种子生活力随着含水量的下降而降低,种子含水量下降到11.6%时,生活力仅为6%;自然脱水过程中,种子细胞膜系统受到损伤,相对电导率不断上升;种子内SOD活性随着含水量下降而呈总体下降的趋势;POD先呈波动性上升,脱水12 h时达到最大值,之后急剧下降。
