Objective:to compare the effects between seed stem and commercial rhizoma gastrodia on memory dysmnesia induced by scopolamine in rat .methods: a month before the scopolamine administration, seed stem and commercial rhizoma gastrodia were given to two groups of young rats with scopolamine–induced dysmnesia model, incubation period of findingplatform were measured by means of morris watter-maze.

目的比较天麻种麻与天麻商品麻改善东莨菪碱诱发的记忆障碍的疗效。方法用天麻种麻，商品麻灌胃饲养幼鼠一个月，然后用东莨菪碱诱发大鼠造记忆获得性障碍模型，通过morris水迷宫测试大鼠寻找平台的潜伏期。

It was found in this investigation that boron exerted considerable influenceon the nucleation and growth of pearlite. In a hypoeutectoid steel, boron delayedthe starting time of pearlite formation at the maximum pearlite formation temp-erature. Boron did not effect the relation of nucleation rate with time butonly increased the incubation period for pearlite nucleation.

从实验结果证明，硼对珠光体的成核及成长是有影响的；在亚共析钢中硼促使珠光体的开始形成时间推迟，增长了珠光体成核的孕育期，但对成核率与时间的关系，在近于A_1温度(700℃)时，略为加速，而在珠光体转变速度最大的温度(650℃)时却没有影响。

Monogene Ht1, Ht2, Ht3, and Ht were crossed with inbreds of same resistant level and different resistant level to study the monogenic effects and polygenic effects on spots number, size, spread speed, spore production and incubation period.

通过单基因Ht1、Ht2、Ht3、Ht，与同一水平抗性自交系以及与不同水平抗性自交系组配，研究单基因处于杂合状态时在控制病斑数量、面积、病斑扩展速度、产孢量和潜伏期等方面的单基因、多基因的联合效应。

The results showed that resistant gene Ht in F1 heterozygote was the most effective on controlling spots number and size; all monogene in heterozygote could produce spore by moisture culture and resistant gene Ht1 was the most effective; resistant gene Ht1 in medium level, Ht3 in high level, and Ht in low level of vertical resistance of heterozygote, were the most effective on controlling spots spread; while Ht2 in high level of vertical resistance of heterozygote was the most ineffective on controlling spots spread; and all resistant monogene in heterozygote showed superior to their parents on controlling incubation period and gene Ht was more significant than other genes.

结果表明，抗性单基因Ht处于F1代杂合状态时，控制病斑数和病斑面积的效应最强；单基因处于杂合状态时，湿培48h病斑全部能产生分生孢子，且处于同一水平抗性杂合状态时，Ht1控制产孢量的效应最强；Ht1处于中水平、Ht3处于高水平和Ht、处于低水平垂直抗性杂合状态下，控制病斑扩展效应最强；而Ht2处于高水平垂直抗性杂合状态下，控制病斑扩展效应最弱；抗性单基因处于杂合状态下，控制潜伏期多表现超亲现象，Ht控制病害潜伏期比其它单基因显著。
