Composition of both spermatophyte and pteridophyte flora of a relict Alsophila spinulosa community in Wutongqiao Nature Reserve of Leshan region was discussed. It shows the proportion of Tropic and Cathaysia elements in both spermatophyte flora and pteridophyte flora was almost 2/3 of the total at the genus level, and even more at the family level. There was a distinct ancient endemism phenomenon in spermatophyte flora, owning to being 8 relict and remnant endemism genera in the total of 9. Furthermore, the proportion of Tropic and Cathaysia elements both at family and genus level in the pteridophyte flora were much greater.

选以乐山五通桥桫椤自然保护区-桫椤群落的种子植物区系与蕨类植物区系组成为研究对象，发现种子植物区系在属的水平上热带成分与古华夏成分占到近2/3，在科的水平上则更高；种子植物区系中有9个中国特有属，其中8个为残遗或原始类型的古特有属，表现出典型的古特有现象；而在蕨类植物区系中热带成分和华夏成分所占比重更大。

Results There was no obvious discrimination of the seed morphology between AMM and AM.

结果通过肉眼和光学显微镜观察，两种黄芪种子的形态差异不明显，在电子显微镜下观察，两种黄芪种子的萌发孔形状、种脐和种皮的微观结构有明显差异；蒙古黄芪较膜荚黄芪种子硬实率高，萌发不整齐，萌发高峰滞后。

Studies on the autointoxication of Chinese fir show that the aqueous extracts of surface soil, leaf litter, half decaying leaf litter, fresh leaf, branch, bark and root in pure Chinese fir plantation and their polyvinyl pyrrolidone k30 solutions affected the seed germination of Chinese fir, Raphanus sativous and water convolvulus.

对杉木自毒作用研究表明，杉木纯林中的土壤、枯落叶、半分解枯落叶和杉木鲜叶、枝条、树皮、树根的水浸液及其添加乙烯吡咯啉酮k30 的溶液对杉木种子、空心菜种子和萝卜种子的萌发均有影响。

In the thesis, we choose six wild species in northeast of China to study the configuration, physiological characteristic, peculiarity of dormancy and bourgeon as well as seedlings growth process. The results as follows:(1) Morphological difference of six species in Iris is obvious.

基于此目的，本论文以东北野生鸢尾属中的6种典型植物为研究对象，从种子形态结构、种子各项生理指标(包括生活力、含水量、吸水性)、种子的休眠与萌发、种苗的发育过程几个方面进行研究。

Greenhouse experiments were conducted to study (1) response of seed germination and seedling emergence to depths of sand burial in Caragana microphylla Lam.

由于这两个种的种子萌发是光敏感的，所以它们的种子萌发受土壤含水量和光照强度二者之间的平衡调节。2 cm的较浅沙埋最有利于种子萌发和出苗。

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。

It could preferably defend seedlings against damping-off and Rhizoctonia rot in seedling stage, wilt disease and anthracnose in mature phase and increase field. After application in cowpea, Fenle Nutritious Seed Coating for beans and ZSB bean seed-coat agent (1:40 for ratio of the chemical to seeds) were selected, which increased emergence rate and improved seedling growth.

在豇豆种子上包衣应用后，筛选出效果较好的丰乐营养豆类包衣剂（药种比为1：40）和ZSB菜豆包衣剂（药种比为1：40），提高了豇豆种子的出苗率，促进了幼苗的生长，同时种衣剂对豇豆种子本身所带的炭疽病病菌和土传的猝倒病、枯萎病均有显著的防效，从而一定程度上提高了豇豆的产量。

The seed is an important agriculture production datura, Influenced by the plan system, the tradition seed industry lead to the seed proprietor's consciousness about competition is not strong, and the study of the seed marketing is also not much.

种子是重要的农业生产资料，传统种业受计划体制的影响，种子经营者竞争意识不强，对种子产品的营销研究也不多。

The author thought that we must establish the concept of developing with the contemporary era ,innovate determinedly and dauntlessly in idea,system,technology,Geniuses management and culture of enterprise in order to put seed industry into developing continuably and successing greatly.

《种子法》的颁布实施和我国加入WTO，给予种子产业带来了前所未有的发展机遇，也使种子产业面临着严峻挑战，我们必须与时俱进，从观念、体制、技术、人才、管理、企业文化等方面，锐意创新，求得种业的健康持续发展，实现种业新的历史辉煌。

The germination ability of wheat seeds was stronger than that of maize seeds.For example,the germination rates of Liaochun-9 were higher than those of Longmai-26.The effects of 1# deicer on the germination of different maize seeds were not distinct different.While the germination rates of Mingyu-2 were higher than those of Naihanyuyu after the treatment of 2# deicer.

在融雪剂胁迫下，小麦种子均表现出比玉米种子较强的发芽能力，且辽春9号比龙麦26号发芽能力更强。1#融雪剂对玉米种子发芽的影响无明显差别，但在2#融雪剂处理中，明玉2号较耐寒豫玉发芽能力强。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
