抗旱

In this paper we compared the leaf areas, morphology of leaf epidermic hairs and stomata in four varieties of sea buckthorn ( Hippophae rhamnoides L.).

观察比较了抗旱性不同的4个沙棘品种的叶片大小、叶片表皮毛和气孔的形态特征。

The results indicated that leaf area, layers of epidermic hairs, stomata area and

说明叶片大小、叶表皮毛层数和气孔大小、气孔密度等指标与沙棘抗旱性密切相关。

For IDR, 3 additive and 2 pairs of epistatic QTLs were identified.

Basing on our early stage research work about collection and description of sugarcane germplasm and the aided project of Yunnan Natural Science Fund (2001 C0015Q), the wild species Erianthus fulvus, which has good characters, cold-resistant, drought-resistant, higher Brix and less chromosome number, was utilized for the first time through intergeneric hybridization with sugarcane cultivar. Its F_1 hybrids were appraised with some new techniques and methods for germplasm enhancement.

本研究在课题组考察采集和保育鉴定甘蔗野生种质资源的前期工作基础上，依托云南省自然科学基金资助项目(2001C0015Q)，首次利用具有特异优良性状(抗旱、耐寒、锤度高、染色体数目少)的蔗茅野生种与甘蔗栽培种或品种进行属间远缘杂交，扩大甘蔗遗传多样性；采用新技术、新方法对蔗茅杂种F_1代材料进行早期鉴定评价研究，筛选具有育种价值的新种质，为进一步选育生态适应性广、抗逆性强、丰产高糖的甘蔗新品种奠定物质基础。

Medicago falcata L. belongs to drought avoidance type in the method of drought resistance.

在抗旱方式上，黄花苜蓿属于干旱避免型。

Medicago falcata L. is a perennial herb in leguminosae. There are many excellent characteristics which are cold and drought resistance, salt tolerance, windy and dusty resisting, leanness tolerance and diseases and pests resisting.

黄花苜蓿是豆科苜蓿属多年生草本植物，具有抗寒、抗旱、耐盐碱、耐风沙、耐贫瘠，抗病虫害等优良特性。

This study is one part of the united project of Inner Mongolia Agricultural University and Ordos Foresty Bureau which named"The Study of Ordos Plateau Several Caragana Species Distribution, Resistance drought Afforestation and Exploitatin."The study was supported by this project.

本研究属于内蒙古农业大学与鄂尔多斯市林业局横向联合课题&鄂尔多斯高原锦鸡儿属几个种的分布及抗旱造林与开发利用的研究&的一部分，研究内容得到了该课题的资助。

Additionally,we specially tested seeds antioxidant enzyme and protein of Hedysarum scoparium under drought stress or recover condition,and the Peganum harmala characteristics of seed traits and communities distribution to find out the mechanism of resist-drought.

同时，我们还研究了骆驼蓬的种子特性及群落分布特点，这些研究结果均有助于我们进一步了解植物种子的抗旱生理生化机制和群落分布规律，为荒漠治理及优势群落的发展与保护等提供理论依据。

In this experiment, we found the water of wheat leaves increase 0.6%~3.06 % for wet weigh and 17%~99.73 % for dry weigh,The oppositely containing the water increase 0.24%~3.42 %, The water saturation decrease 0.24%~3.39 %.The resulte of the leaves of corn is similar with wheat. it indicates that treat with extracts of peganum harmala could enhance the drought resist ability of wheat and corn.

试验结果表明，凡种子经过处理后，小麦叶片水分占鲜重的量增加了0.6%~3.06 %，占干重的量增加了17%~99.73 %，相对含水量增加了0.24%~3.42 %，而水分饱和度降低了0.24%~3.39 %；玉米处理结果与其一致，表明浸种处理具有增强作物抗旱性的生理效应。
