不同温度条件下玉米生长速度及植株外部形态的比较

Comparison of Speed of Growth of the Maize and External Forms of Plant Under Different Temperature Condition

试验调查并分析了两种不同的温度条件———田间正常温度和玻璃温室内温度,对玉米的生长速度及其外部形态的影响。结果表明:温度对玉米的叶片宽度、叶片增长速度及出苗时间影响很大,而对玉米6月23日(夏至)的叶片数及植株总叶片数基本无影响。

This experiment investigated and analyzed that two kinds under different temperature conditions-normal temperature in the field and temperature in glasshouse which affect on the speed of growth and external forms of the maize The result of the experiment indicated temperature effect greatly maize in leaves width leaf rising speeds and the time of seed coming out from soil but effect rarely all leaves of a plant and leaf number in the June 23 the summer solstice.
