种子植物

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。

What's worse, they think that the temperature condition is not necessary for seeds to come into leaf and that plants can also grow well without fertilization.

学生对於植物生长的另有概念包括将根与茎的名词定义错误，认为植物是「先长茎再长根」或「先长果实，后开花」；并对植物器官的功能不熟悉；缺乏植物的「花」、「果实」具有传宗接代等繁殖概念；「温度」条件对种子发芽而言是非必要的；植物有「施肥」就长得更好，没有施肥也不会怎样；知道植物可以用种子繁殖，除了种子以外可以繁殖的器官学生多数只看过落地生根用叶子繁殖，缺乏更多的实际经验。

In the present study, the effect of salinity on the germination for euhalophyte and xerophyte, and the strategies for adaptation of halophytes to extreme saline and arid environments in Xinjiang during seed germination stage were investigated;the osmotic adjustment traits of euhalophyte and xerophyte were also investigated in field and controlled conditions.

Arabidopsis response regulators,ARR4 and ARR5, were induced by the increased cytokinin contents at different time after seed germination. ARR4 responded to cytokinins at early time of seed germination, especially on the 6 d when seedlings were around true leaf initiation, while cytokinins induced ARR5 activation after 6 d of seed cultivation in light conditions, an obvious increase was on the 20 d when seedlings were around inflorescent shoot initiation.

The galactosyl oligosaccharides of raffinose series are widely distributed in seeds of many species and are localized in tissues that remain viable after desiccation, including the embryo and aleurone layer of cereals, cotyledons and axis tissues of legumes and other dicots.

棉子糖半乳糖苷系列寡糖广泛分布在许多种植物种子中，并存在于干燥后仍能保持活力的组织内，如禾谷类种子的胚及糊粉层，豆类及其他双子叶植物的子叶和胚轴组织等。棉子糖半乳糖苷系列寡糖在禾谷类种子的非自溶性中央胚乳中不合成，但存在于蓖麻种子的自溶性胚乳细胞中。

The correlation was attributed to the three types of plants:(1) the ephemerals plants;(2) the plants that had the transient soil seed bank or the aerial seed bank;(3) the plants of mainly vegetative propagation.

土壤种子库特征以及与地上植被的关系主要受以下几种植物的影响。1。短命植物；2。仅形成短暂种子库或是大部分时间形成空中种子库或土壤外种子库的植物；3。种子繁殖能力弱而营养繁殖能力很强的植物。

The density of the foot 、middle part and top are 124grain /m~2、91 grain /m~2、66 grain /m~2,the seeds is more little windward than the leeward.The density of seed banks in windward is 81grain/m~2 and the leeward density is 100grain/m~2.The seed of ephemerals bourgeoning reaches the pinnacle on April and May.The diversity of different parts sand dune is different,but the differences do not reach the marked level.The similarity is high between the seed banks and the vegetation.
