对日照

Up to date,many detailed researches on photoperiodic control of flowering time have been clear-cut in long-day model plant Arabidopsis thaliana.

光周期诱导植物开花的现象在被子植物中广泛存在，目前对长日照的模式植物拟南芥的光周期控制开花时间的研究较为详尽，而近年来，许多研究表明不同的植物间光周期控制开花反应具有很大的保守性。

DPU at a concentration of as low as 10^(-7)mol/L retained the chlorophyll of Spirodela half-fronds under long-day conditions. From 10^(-5)~2×10^(-4)mol/L it prompted the synthesis of chlorophlly and the serine: glyoxylate aminotransferase activity, increased dry weight, and retarded the senescence of half-fronds.

在长日照条件下，10^(-7)mol/L的二苯脲对紫萍半叶状体就有保绿的作用，10^(-5)~2×10^(-4)mol/L的二苯脲还可以明显地促进叶绿素的合成和干重的增加，提高丝氨酸：乙醛酸转氨酶的活性，延缓半叶状体的衰老。

2Photoperiod had distinct effects on account of flower、 diameter of flower and florescence,long-day length improved the quality of flower.

光周期对"白雪塔"、"花牡丹"的花期、开花数量、花朵直径有影响，在各长日照处理下，开花质量提高。

Photoperiod sensitivity can limit the geographicadaptation of Brassica napus to a great extent. For example, Q2, used as one parent in thisstudy which is one spring and photoperiod-sensitivity Brassica napus, only can be plantedin the long-day region as a summer crop for ensuring maturity and yield of seed.

光周期敏感性对春性甘蓝型油菜的种植地理适应性有较大的限制，例如光周期敏感性较强的油菜品种(如本试验的亲本Q2)只有作为夏季作物种植在长日照地区才能保证菜籽的正常成熟和产量。

Currently Taiwan relies on imports for 98 percent of its energy, the majority of which is crude oil. However, in Penghu the daily supply of sunlight is equivalent to a million barrels of oil. And with the northeasterly trade winds in September, the combination of wind and solar power is creating new opportunities for Penghu.

台湾目前有百分之九十八的能源仰赖进口，而且主要都是原油，但对澎湖来说，太阳每天的照射量就相当於百万桶的石油能源了，再加上每年九月的东北季风，风吹和日照，就是开创澎湖生机的开始。

Eating osmund often can not only complement the nutrition necessary to human body, but also can recuperate the health of the pregnant woman and the patients who lack of sunshine and be ill for a long time, The osmund is regarded as the high-grade goods for food.

经中日两国营养学家鉴定，常实用薇菜不仅能够补充人体所必需的营养物质及微量元素，而且对运动量不足，受日照少，疲劳过度，长期患病的人有良好的调理作用，是一种上乘食补佳品。

Eating osmund regularly can not only supplement the nutrition necessary to human body, but also can recuperate the health of the pregnant woman and the patients who lack of sunshine and be ill for a long time; the osmund is regarded as the high-grade food for health.

经中日两国营养学家鉴定，常食用薇菜不仅能够补充人体所必需的营养物质及微量元素，而且对运动量不足、受日照少、疲劳过度、长期患病的人有良好的调理作用，是一种上乘食补佳品。

In the finality, the temperature profiles and thermal effects of the palestra areanalysed by this method and some useful conclusions are acquired which can bereferred by constructions.

最后使用此分析方法，对某大型露天体育场的看台结构进行了日照作用下的温度场及温度效应分析，得出一些有益的结论，以供实际工程参考。

The effects of sunshine and precipitation on phenology phase changes are different because of the difference of the geographical location and the growing phases.

日照和降水对物候期变化的影响，由于其地理位置和生育时段的不同而呈现各不相同的关系。

The effects of photoperiod and temperature on cold hardiness The high temperature and short photoperiod could decline the supercooling ability.

3光照和温度对滞育后大猿叶虫耐寒性影响高温和短日照可降低大猿叶虫的过冷却能力。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
