The eco-physiological characteristics of drought endurance of Pinus sylvestris var.mongolica were studied under different climatic regions, soil water and leaf water condition.Furthemore,the response and adaptability of trees to water stress was done.The below showed the results. 1 The parameters of drought endurance of P. sylvestris var. mongolica was measure and studied by PV technology in the subhumid, semiarid and arid regions The results indicated the osmotic potentials at water saturation condition and at the initial loss turgor decreased as the climatic drought degree increased,and related linearly with the climatic moisture index.It was proved that the drought endurance of P. sylvetris var. mongolica was varible and the elevation of the osmotic adjust capability was a main way to the adaptation of trees to the drought climatic environment.

本文研究了樟子松(Pinus sylvestris var.mongolica)的主要耐旱生理生态特征在不同地区、不同土壤水分状况和叶水分状况下的变化，进而研究了樟子松对水分胁迫的反应和适应，结果如下： 1 应用 PV 技术对半湿润区、半干旱区和干旱区樟子松耐旱性指标测定研究指出，水饱和总体渗透势和初始失膨点总体渗透势随着气候干旱程度增加而增加，与气候湿度指标呈直线相关，证明了樟子松属于耐旱性可变的树种，渗透调节能力增加是其对干旱气候适应的主要途径。

However, the weedy rice has became an another special type for long time evolution and domestication, so its resistance is superexcellence than the cultivable rice, and also become a natural gene storeroom.

然而，经历漫长的自然进化和某种特定稻作环境的驯化，杂草稻已成为稻种资源的一个特殊类型，较野生稻而言，其特殊生物学性状和抗逆性等优良性状易于在育种中直接利用，是水稻品种改良的重要育种资源，同时也是稻种遗传进化研究的必备材料。杂草稻长期自然生长繁衍，其抗病、虫、寒、旱、盐碱等特性优于栽培稻，而且与栽培稻的亲缘关系相对接近，是一种改良栽培稻抗逆性的天然基因库。
