These results suggested that many organella could all develop into amyloplast, variation of amyloplast envelope resulted in amylopast proliferation, RER played an important role in synthesis and deposition of protein, ER showed many functions during endosperm development, intercellular space and plasmalemma invagination played an important role in transportation of nutrients, degeneration of starchy endosperm nucleus was a special PCD, Ca〓 and phosphatases played an important role during endosperm development.

上述结果表明：多种细胞器可以趋同发育成淀粉质体，淀粉质体增殖来源于其被膜的活动，粗面内质网在蛋白质的合成与积累中具有重要作用，内质网在胚乳发育中具有多种功能，胞间隙和质膜内陷在营养物质的运输中具有重要作用，淀粉胚乳细胞核的衰退是一种特殊形式的编程性死亡，Ca〓和磷酸水解酶在胚乳发育中起重要作用。

ER took part in cell wall material deposition during endosperm cell construction. ER rounded up matrix forming endocytic vacuole. ER cisterna swelling and accumulating starch developed into amyloplast. ER took part in protein synthesis and deposition, played a core role in protein body formation. ER swelled at the end to form many vesicles. ER was associated with the plasmodesmata, helped transporting nutrients at the development and differentiation stage.

内质网参与胚乳细胞构建中细胞壁物质的积累；内质网包裹基质形成吞噬体，为胚乳的发育提供营养；内质网槽库膨大，积累淀粉转变成淀粉质体；内质网参与蛋白质的合成与积累，在蛋白体的形成中处于核心地位；内质网末端节状膨胀，形成潴泡；灌浆高峰期内质网常与胞间连丝相连，有助于物质的运输。

The autotetraploid plants were obtained by identifying the characteristics of morphology, cytology, agronomy,and nutrition quality.

采用不同质量浓度的秋水仙素处理子叶期二倍体萝卜茎尖生长点，通过对突变株进行形态学、细胞学、农艺学及营养品质鉴定，获得同源四倍体。

Compared with diploidy , the seedlings of Pasthyrostachys juncea with tetraploidy have stronger viability , higher nutrient contents and better tolerance of lower temperature , drought and other extremely environments .

与二倍体新麦草相比，染色体加倍后的四倍体新麦草的种苗生活力强，种子营养成分含量高，对低温，干旱等极端环境的适应能力强。

The distribution of ubiquitin positive dystrophic neurites and neuronal intranuclear inclusions were investigated. Results Morphologically,it was characterized by marked atrophy of bilateral striatum with loss of neurons and mild proliferation of astrocytes.

泛素阳性的营养不良性神经突起和神经细胞核内包涵体主要出现在大脑皮层的Ⅲ～Ⅴ层，神经细胞核内泛素阳性包涵体在大脑额叶前区皮层达22%，依次为顶叶7%、枕叶3%、颞叶1%和扣带回1%。

In the dissimilar melon breeds, it was different to hormones because of genotypes and endogenous hormones. In a same treatment, the different exhibitions of the induced process were resulted of self-conditions in different explants, including the level of hormones endogen, nutrition, and so on.

不同甜瓜品种在发生不定芽时对激素的需求是不同的，因其基因型和内源激素水平而异；6-BA是诱导甜瓜品种"白兰瓜"发生不定芽的有效激素，添加IAA不利于"白兰瓜"的不定芽诱导；同一处理中，诱导过程中的的不同表现是由不同外植体的自身状况导致的，包括外植体的内源激素水平，营养水平的差异等。

Efficient usage of the main storage material in megagametophyte before it falls off from seedling is important for seed germination of Pinus edulis Engelm.. We examined and compared lipid usage in both megagametophyte and cotyledon with electromicroscopic technique, the length, dry weight, starch content and FBPase activities of each part of the seedling were measured and compared.

采用电镜技术观察了黑暗中萌发中食松子叶和提供营养的雌配子体中脂肪体和与脂肪利用有关的乙醛酸循环体的变化，测量比较了子叶、下胚轴、根的长度、干重、淀粉含量，以及果糖1，6二磷酸酶的活性变化，对贮藏物质脂类、淀粉的利用及与生长的关系进行了分析。

So far, almost all of vegetative and reproductive organs have been regenerated in vitro, which might be helpful to further understand the molecular mechanism of plant organogenesis.

迄今为止，包括营养器官和生殖器官在内的几乎所有的器官都可以在离体条件下得到再生，为深入研究植物离体器官发生的分子机理奠定了基础。

The former one appears in stimulation of worm activity, spasmodic contraction of worm musculatures and severe damage to the tegument, which results in hepatic shift of schistosomes, influence on the nutrition absorption, excretion/secretion and defense function of the tegument, followed by the secondary interference with the worm metabolism.

前者表现为虫体活动兴奋，肌肉挛缩和皮层严重受损，从而导致虫的肝移，影响虫的体表营养吸收、排泌和防御功能以及继发的代谢紊乱；后者因皮层的损害和剥落破坏了虫体在宿主体内存活的伴随免疫机制，其体表抗原的显露为宿主抗血吸虫特异性抗体的免疫攻击提供了靶部位，即吡喹酮的抗血吸虫作用是免疫依赖的。

The nucleus vegetative in nature derived from unequal or equal division of the uninucleate pollen in rye anthers cultured in vitro develops into pollen embryoids or calli.The green haploid plantlets are differentiated successfully.
