To investigate the relationships between the tolerance difference to high temperature stress and superoxide dismutases in different cultivars of Celosia cristata, ten-leaf stage seedlings of the heat-tolerant cultivar, Century Green and the heat-sensitive cultivar, Century copper were pulsed for 48 h with diethyldithiocarbamate pretreatment and subjected to high temperature stress under controlled conditions of relative humidity of 75%~90%, 12 h/24 h photoperiod with 1 500 lx and 45 ℃, to research the changes of external morphology and interior physiology.

李永红；魏玉香深圳职业技术学院应用化学与生物技术学院，深圳 518055摘要为研究鸡冠花品种间耐热差异与超氧化物歧化酶之间的关联，选用鸡冠花耐热品种世纪绿叶和热敏品种世纪铜叶的10叶期幼苗为试材，用二乙基二硫代氨基甲酸钠进行48 h预处理之后，在45 ℃、相对湿度75%~90%，、光照1 500 1x (12 h/d)条件下进行热胁迫处理，研究其形态和生理生化的变化。

From 1956 to 1958, the study of the effects of day length upon the Photostage, floral curve, number of boll and the development of reproductive organs of the Sea Island cotton Gossypium barbadense L.

在10小时日照下的棉株較在自然日照及16小时光照下的棉株其现蕾期及开花期均提早，第一果枝着生节位下降，开花数及結鈴数均显著增加。

Avermectin are 16-membered pentacyclic lactone compounds produced by Strephomyces avermitilis, which have extensive and high effect on many kinds of insect and mite.

阿维菌素是从阿维链霉菌的发酵产物中分离出来的16元大环内酯类抗生素，对多种动物寄生虫及农业害虫害螨有很高的杀虫活性，但是该药剂光照易降解而持效期短。

The effect and its mechanism of temperature during grain filling on rice quality were investigated by using 4 eary-indica rice cultivars with different quality and amylose content. The plants at filling stage were transferred into two phytotrons (Model PGV-36, CONVIRON, Canada), which were set two mean daily air temperatures, i.e. 22℃, optimum temperature regime and 32℃, designed as high temperature regime. The differences in quality properties and starch characteristics of rice between two temperature regimes were determined, and effects of temperature at grain-filling stage on starch biosynthesis in developing rice grains were also analyzed.

本研究以田间异季栽培试验为基础，利用人工气候箱(PGV-36型，CONVIRON)设高温(日均温度32℃)和适温(日均温度22℃)两个典型温度处理，在日温差、光照、相对湿度等因素完全一致的条件下，系统地研究了水稻灌浆结实期不同温度对早籼稻米淀粉的DSC热力学特性、RVA粘滞性、晶体结构、淀粉链长分布等理化指标的影响及其品种类型间的差异，并分析了水稻籽粒淀粉合成代谢过程中几个关键酶的温度效应特征及其与稻米淀粉合成和积累的关系。

Perhaps the short-day treatment of SD is necessary to the fertility.(2): Compared the 88-428 SD(14.8-15.2h/d) with the 88-428 LD(14.9-15.3h/d), a new isozyme band of Rf=0.19 was found for the first time in the leaves of the 88-428 SD from the branching.

大豆光敏雄性不育材料88-428在出苗后经过连续20天的短光照处理后，与长光照条件下的88-428相比，从分枝期起多了Rf=0.19的酶带，特别值得指出的是Rf=0.19的酶带在以后的发育时期内一直存在，说明经过短光照的诱导以后产生了新的物质，而且这种物质可以在细胞间运输，影响到植株的生殖生长。

LED illumination of 590 nm decreased the mating rate from 89.15% in the control to 52.5% in the treatment, and the number of copulations.

本试验的结果还表明，505nm和590nm的LED光照能够改变棉铃虫成虫的产卵动态，使平均产卵期延长2d左右，同时也能显著地降低棉铃虫卵的孵化率，但对棉铃虫产卵量的影响不显著。
