In the exploitatation and utilization of Bromus stamineus, we must take the different sowing methods and plant densities into account. They have heavy influences on the forage especially in terms of the forage growth. The salt, temperature and water are important factors that affect the seeds germination,which deciding the germination time and germination place.we designed four temperature (15℃,20℃,25℃,30℃) and NaCl density(0.3%,0.6%,0.9%,1.2%) and PEG density(0.126g/gwater,0.186 g/gwater,0.232 g/gwater,0.270 g/gwater).

引进美国无芒雀麦是农业部948项目&旱生灌草植物资源的引进及开发利用&的引进草种之一，为了合理开发和利用它，本论文对引进无芒雀麦和本地无芒雀麦的种子萌发、田间种植和栽培技术3个方面进行了对比研究，比较了两种无芒雀麦生长特性；结合方差分析，确定了引进美国无芒雀麦种子萌发指标和栽培技术指标。

Cacao tree is a kind of small arbor tree and it has the following outstanding features. First, cauliflory: its flowers burst open on the tree trunks directly and then the flowers will produce fruits on the tree trunks too. The cacao flowers are small, but the fruits are big. The fruits are elliptical and have many ridged lines on the outer skins. The color of the fruits is yellow, and each fruit can grow as heavy as one kilogram. Each cacao plant can grow 60 to 70 fruits, and there are about 30 to 50 seeds in each fruit.

可可是一种有趣的梧桐科小乔木，它最大的特点是&老茎生花&和&老茎结果&，花直接开在树干上，果也直接结在树干上，花小而果实大，果子呈椭圆型，表面有一条条棱形线突出，橙黄色，每个果子重达1千克左右，每株可可树可结60-70个果子，一个果子内有30-50粒种子，巧克力的原材料就是这些种子。

High salinity and temperature induce seeds of euhalophytes Halostachys caspica, Kalidium foliatum and Halocnemum strobilaceum to remain ungerminated, and seeds germination and seedling establishment of the three halophytic species can be ensured only when temperature and edaphic conditions are favorable. This is most likely an important adaptive strategy in these halophytic species to survive their saline environment in an arid region in Xinjiang;(2) morphological adaptations.

三种真盐生植物盐穗木、盐爪爪和盐节木种子在高盐和高温时不萌发，只有当温度和盐分适宦时种子才萌发，有利于幼苗的成活，是这三种植物适应新疆极端生境的策略。

Racemes axillary or terminal, appendage lamellate; unwinged part of capsule without obvious concentric ribs; seeds ovoid or hirsute-villous, not strophiolate, or pubescent and strophiolate

总状花序腋生或顶生，附属物片状；无翅部分胶囊没有明显的同心的肋骨；种子卵球形或长硬毛状柔毛，并非strophiolate，或短柔毛和strophiolate 27

Leaves opposite or alternate, stipules absent; petiole often indistinct; leaf blade simple, usually pinnately veined, margin entire.

Through the diversity investigation of weed in large area of white clover seed production atMaming （1）In the seed production of white clover in large area, by the growing of white clover, the species and quantity of weed are increasing rapidly;（2） Because the growth speed of white clover is slower than other grass in the seeding year,the early field management is effect to prevent the fast growth of the weeds.

通过对农业部白三叶种子生产项目在云南省马龙县马鸣乡大面积生产中杂草的多样性调查，结果表明：（1）在白三叶种子大面积生产中，随着白三叶的生长，田间杂草的种类和数量逐步增加；（2）由于在白三叶播种当年其生长速度不快，因而在其生长前期应适时除杂，以防止杂草的迅速生长。

With the seeds of artificially cultivated 2-year-old A. heterophyllum as tested materials, the cells in metaphase in the seeds were made for observation, statistic and karyotype analysis, and based on the 2 main features of length ratio and arm ratio of chromosome, the karyotypes were classified according to the criteria of Stebbins.
