The results indicated:(1)The Phyllostachys edulis could be distinctly distinguished from two affined species in the same genus.

结果表明，( 1 )RAPD技术能将 7个毛竹的变型或栽培型与同属的两个近缘种明显区别开来。

Nine samples(seven cultivars or forms of Phyllostachys edulis and two affined species.)were tested with RAPD in order to assess their genetic relationship.

From differentiation of soybean varieties and photoperiod adjustment, anatomical differentiation essence of different types of stem termination soybean varieties, variation law of stem termination development under different photoperiod treatments, effect of long day on the terminal raceme of soybean, regulation rules of AGAMOUS gene among different soybean varieties and under different photoperiod treatments were studied, which would provide theory base of plant type breeding of soybean especially improvement of podding-habits and cultivation and management of soybean.

因此，试验于2006和2007年在中国农业科学院作物科学研究所完成，主要从大豆的品种差异和光周期调控入手，利用解剖学和分子生物学技术，研究不同结荚习性大豆品种的本质差异、大豆在不同光周期处理下茎顶的变化规律，进一步明确长日照对大豆顶端花序的影响，及AGAMOUS基因在不同光周期处理下大豆品种中的表达规律，为大豆株型育种特别是结荚习性的改良及大豆栽培管理提供理论依据。

Agaricus bisporus on the nutritional value, medicinal value and cultivation techniques for analysis.

In this paper, the chemical constituents of essential oil of Agastache formosanum Hay.,planted in Dunhuang of Gansu Province of China, have been studied by capillary gas chroma-tography-mass spectrometry.

本文介绍采用毛细管气相色谱-质谱法研究了甘肃敦煌栽培的茴霍香精油的化学成分。

The content of mineral elements in ripe fruits of M.sieversii from 78 seedings at Mohe Town,Gongliu Country were analyzed using Atomic Absorption Spectrophotometer.The results indicated that M.sieversii seedings presented considerable genetic variations in content of mineral elements with the range of variation coefficients from 24.2% to 54.0%.So it has large potential for further selection.Four elite seedlings were selected,namely large fruit type,high Ca content type,high Zn content type and high damascenone content.As the predominant component of Ily wild fruit tree forest,Malus sieversii had occupied an area of 9300ha.But the inherent reproduction system of M.sieversii and genetic diversity of the species were destructed in different degrees,as a result of farming assart,over grazing and damage by Agrilus mali.

上述结果支持&新疆野苹果可能是栽培苹果祖先种&的结论；②对巩留县莫舍乡的新疆野苹果78个实生株系果肉组织Ca、Mg、Fe、Zn、Cu、Mn6种矿质营养元素进行测定的结果表明，每种矿质元素含量单株间差异显著，变异系数在24.2％～54.0％，遗传多样性丰富，进一步选择的潜力很大；③根据新疆野苹果果实形态、香味物质和矿质元素含量等的测定结果，初步筛选出了大果型、高钙型、高锌型和大马酮型等4个特异性状单株；④调查发现，由于农田开垦、过度放牧以及苹果小吉丁虫的蔓延危害，目前伊犁野果林面积逐年减少，野苹果固有的繁育体系和遗传多样性受到不同程度的破坏。
