光周期的

In order to investigate the light cycle on the basis energy expenditure of tree sparrows and the effects of gonadal weight, we domesticated tree sparrow with temperature 25℃, three kinds of photoperiod in the climate box for four weeks, and then measured tree sparrows body weight, basal metabolic rate, as well as gonadal organ's fresh and dry weights.

中文摘要：为探讨光周期对麻雀基础能耗和性腺重量的影响，对25℃和三种不同光周期的麻雀进行4周人工气候箱驯化后，我们分别比较了雌和雄麻雀的体重、个体 BMR 和性腺的鲜重和干重。

When temperature arrived to 30℃, no individual went to diapause whether daylength short or long.

温度对滞育的影响受光周期的影响，在相同光照条件下，在一定温度范围内，随着温度的上升，滞育率下降，当温度上升幅度达到30℃，无论长短光照条件下均不出现滞育个体。

But the proportion of diapause increased if the eggs laid by females in all day light.

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。

Photoperiodic counter is an important part of photoperiodic response. It accumulates and stores photoperiodic information contained in a sequence of light-dark cycles.

光周期计数器是光周期反应系统的一个重要组成部分，它累积和储存光周期循环中的光周期信息，当存贮的信息总量超过一个内部阈值时，诱导(滞育和非滞育；有性和无性)就会随之发生。

Induction (diapasue and nondiapause; sex and non-sex) supervenes when summation surpasses the internal threshold. The review reports some characters of the photoperiodic counter in insects and mites, including the following aspects:(1) the accumulation of photoperiodic information during photoperiodic sensitive period of insects.(2) the thre...

本文报导了昆虫和螨类光周期计数器的一些特点，主要包括以下几方面的内容：(1)光周期信息的积累主要发生在光敏感期内；(2)光周期信息的积累存在一个阈值，即需要积累一定数量的长夜或短夜循环去诱导50%的个体发育或滞育；(3)光周期信息的积累受温度、地理纬度和食料的影响；(4)长夜和短夜循环的光周期信息积累的方式；(5)光周期信息的积累的数量反应和质量反应；(6)光周期计数器的内分泌调控。

This research take late-maturing variety adzuki bean Jihong-4 as the experiment material, After the photoperiod inducement at different leaf ages treatment, the result showed that the activity of NR under LF treatment is higher than CK treatment on the whole, and is lower than SD treatment; The content of the dissociation amino acid under these three treatments show a descend trend along with the leaf ages accretion, but the inducement increasing the content of dissociation amino acid, different leaf ages leaves show some difference, and alternating rise with SD treatment; Inducement can reduce the content of soluble sugar, and continuous inducement shows a accumulation effect; 2LF is the most sensitivity stage for soluble protein under photoperiodic inducement, From this stage, each leaf indumenta can reducing the content soluble protein, but continuous inducement reducing rising it.

本研究通过光周期诱导的方法，对中晚熟品种冀红4号红小豆进行不同叶龄进行处理，结果表明：所有叶龄处理下硝酸还原酶活性基本高于自然光处理而低于连续短日照处理下的；随着叶龄增大，各处理游离氨基酸总量均呈下降趋势，但光周期诱导可提高游离氨基酸含量，不同叶龄表现有所差异，与连续诱导交替上升；诱导可降低可溶性糖的含量，并连续诱导出现累积效应；2LF是光周期诱对可溶性蛋变化最敏感的时期，这个时期起单个叶龄诱导可降低可溶性蛋白含量，但连续诱导却可提高；LF处理下的类胡萝素总体含量高于另两个处理，而LF处理下的叶绿素含量在仅3叶龄前高于CK处理下的，随后出现下降趋势。

In order to make a further illumination of the inter-relationship of photoperiod and temperature in soybean growth and development, soybean cv. Heihe 27 and Zigongdongdou which are insensitive and sensitive to photoperiod, respectively, were treated with different photothermal combinations in phytotrons. The relationship of GmFT expression and photothermal response was analysized.
