Using the small plot arrangement method, the comparative test was carried on the field characters of strawberry between tissue culture seedlings and self-reproducing seedlings.

方法］采用茎尖组织培养法获得草莓脱毒苗，并按小区间比排列法进行草莓组培苗和自繁苗田间性状比较试验。

Result The tissue culture seedlings of strawberry were superior to the self-reproducing seedlings from the aspects of botany characters, fruit characters, yielding ability and disease resistance and so on.

结果］草莓组培苗在植物学性状、果实性状、丰产性及抗病性等方面均明显优于自繁苗。

In the low B condition of the soilless culture, rapeseed seedlings were short of B, the seedlings were short and the leaves were malformed and the weight of the shoots decreased, the branch roots were fewer and snuff color, the weight of roots decreased, and the length of root and the ratio of shoot/root decreased, too. However, the high B- efficiency type of rapeseed had the a great ability to the low B stress, the growth of shoots and roots were better than the low efficiency, and the B concentration range of the rapeseed varieties which responded to the B scarce was 0.001 mg/L to 0.01 mg/L.

营养液培养条件下，苗期缺硼，甘蓝型油菜植株瘦小，叶片皱缩，地上部生长量下降；侧根少且呈现黄褐色，根重、根体积、根长以及根冠比下降；高效品种具有较强的耐低硼胁迫的能力，表现为同等缺硼条件下，对高效品种地上部和根系生长的抑制作用都相对较小，且品种间对缺硼反应差异最大的硼浓度范围为0.001mg／L—0.01mg／L。

Using different concentrations of PEG solution simulated drought stress, measured PB86, PR107, RRIM600 and GT1 rubber tree seedling leaves relative water content, the relative conductivity, malondialdehyde, soluble sugar content, superoxide dismutase, 8 physiological indicators, and their changes in the law, and using principal component analysis, membership function analysis, correlation analysis grey mathematical statistical methods, such as the evaluation of four strains of rubber tree seedlings and with the drought resistance the relevance of indicators; at the same time analysing the use of hypertonic solution screening rubber tree seeds and the drought resistance of different rootstocks on 7-33-97 budding seedlings of the impact of drought that rubber tree planting material and rootstocks drought assessment, and provide a theoretical basis choice.

利用不同浓度的PEG溶液模拟干旱胁迫，测定了PB86、PR107、RRIM600和GT1橡胶树实生苗叶片相对含水量、相对电导率、丙二醛、可溶性糖含量、超氧化物歧化酶等8项生理指标，研究了它们的变化规律，并利用主成分分析、隶属函数分析、灰色关联分析等数理统计方法评价了4个品系橡胶树实生苗的抗旱性及其与各指标的相关性；同时分析了利用高渗溶液筛选的橡胶树种子的抗旱性以及不同砧木对热研7－33－97芽接苗抗旱性的影响，以为橡胶树抗旱砧木和种植材料的评价、选择提供理论依据。

Because Fov also existed in the roots ofsymptomless seedlings and the stems of both symptomatic and symptomless seedlings afterinoculation,the induced SOD isozyne seems to be originated from plant,not Fov.

由于在接种但未显症的棉株根中和显症或不显症棉株的茎中均可高频率地分离到Fov，因而初步判断该诱导性SOD酶源于棉花基因组中的某一SOD酶基因被活化。
