Based on the settings and geological and geochemical characteristics of granitoids of different orogenic belts (exemplified by orogenic granitoids in Altay, East Kunlun, Yanshan in North China, Northeast China and Nanling in South China), the relationships between granitoids and continental crustal growth are discussed, and five modes of continental crustal growth in the continent of China are proposed;they are as follows:(1)the Altay mode of continental growth is that the material and heat of the Paleozoic convertive mantle formed on the background of the Paleo-Asian Ocean were input into the Paleozoic continent and mixed with the materials of the upper crust;(2) the East Kunlun mode is that the basement of the Proterozoic orogenic belt was reworked by the heat input and materials of the Paleozoic-early Mesozoic convective mantle formed on the background of TTG continental crust of the Proterozoic orogenic belt;(3) the Northeast China style is that the Phanerozoic continental crust was reworked by the heat input and materials from the convective mantle formed on the background of the Yanshanian Central Asian orogenic belt;(4) the Yanshan mode is that the Archean basement was reworked by the heat input and materials from the Yanshanian convective mantle;and (5) the Nanling mode is that in South China what was input by the Yanshanian convective mantle into the continent was mainly heat and subordinately materials and the crustal material recycle was the dominant mode for the continental growth (showing zero continental growth).

根据不同造山带花岗岩的形成背景，地质地球化学特征差异，以阿尔泰，东昆仑，华北燕山，东北和南岭造山带花岗岩为例讨论花岗岩与大陆地壳生长的关系，区分出中国大陆的5种大陆地壳生长方式：阿尔泰式是古亚洲洋背景上形成的古生代对流地幔物质，热输入和上地壳混合为主的方式；东昆仑式是元古代造山带TTG陆壳背景基础上古生代—早中生代对流地幔物质和热输入，改造元古宙造山带基底的方式；东北式是燕山期中亚造山带背景上对流地幔物质和热输入改造显生宙陆壳的生长方式；燕山式是燕山期对流地幔物质和热输入改造太古宙基底的方式；南岭式燕山期对流地幔输入大陆的是以热为主，物质为辅，大陆地壳生长是以陆壳物质再循环为主的生长方式。

The observation of morphogenesis of flower buds in this stage shows that this early floral buds have only perianth primordia at most, and no sex organ primordia yet.

综上所说，黄瓜的性别表达过程应该是多激素共同作用的结果，并且每一种内源植物生长物质对黄瓜性别表达的作用应该有一定的阈值。

With the increase of hormone level added into MS medium,callusing frequencies of type Ⅰ,Ⅱ hairy roots were increased,at the same time,the formation of lateral root from hairy root or callus was inhibited.

随着植物生长物质添加含量的增加，Ⅱ型发状根的愈伤组织化程度也加大，同时也抑制了从发状根或其形成的愈伤组织上形成新的分枝侧根。

Compared with the control, the seedling heights, fresh root weights and total fresh weights in treatments of fermentation liquid and fermented shoots and leaves of Bahia grass were higher and heavier than in that of controls.

试验结果表明：新鲜百喜草茎叶中同时含有AM真菌生长促进物质和抑制物质，生长促进物质主要存在于0～25％的甲醇溶提物中，并以25％甲醇溶提物的生长促进作用最明显，生长抑制物质主要存在于 100％甲醇溶提物中。

The expression patterns of expansin and XTH family genes in cucumber fruits and their responses to plant growth substances were studied.

研究了扩张蛋白和木葡聚糖内糖基转移/水解酶家族基因在黄瓜果实发育中的作用及其对植物生长物质的响应。

This experiment, in the studied foundation of the predecessor, further selected off-season garlic cultivars, regulated the off-season cultivation garlics bulb growth with applying the technology of the plant growth regulator and dark-breaking, enriched the basis theory of research to the growth of the garlic scape and bulb, and provided the basic for the garlic off-season cultural technique.

本试验在前人研究的基础上，进一步筛选了反季节栽培大蒜品种，并应用植物生长物质和暗期光中断技术对反季节栽培大蒜的鳞茎发育做了研究，丰富了蒜薹和鳞茎发育的理论，为大蒜反季节栽培技术提供了依据。

Some strains of the nematode-bearing bacteria were bioassayed for their parasitism. All these bacteria can totally not grow or grows badly on the media incorporating the extracts of pine trees, indicating some substances existing in the trees will harmful to the bacterial strains, which is further convinced by preliminary inoculation showing that single bacterial species will not infect Pinus thugbergii. Hence, the growth and reproduction of the nematode-carrying bacteria, which could produce toxic substances causing the death of the tree cells, is closely related to the nematodes, when they first enter to the trees. In the same time, the activity of bacteria improved the circumstances for which nematodes are living, which in turn will beneficial to the growth of nematodes. Thus, there is a complicated interaction among nematodes, bacteria, and pine trees.

对松材线虫携带的细菌的部分菌株进行了寄生性测定，表明这些细菌在添加松树提取液的细菌培养基中不能生长或基本不能生长，这说明松树体内可能存在某些不利于细菌生长的物质，同时初步的接种试验证实，单独的细菌接种不能感染健康的黑松，因此，线虫携带的致病细菌在最初进入树体时，其生长和繁殖与线虫密切相关，结合细菌产生的毒性物质可造成黑松细胞死亡的情况，说明细菌的生长与线虫有关，同时，细菌的活动改变了线虫在松树内的生长环境，使环境变得有利于线虫的生活，因此，线虫、细菌和松树三者存在着复杂的生物关系。
