Effect of Foliar Application of Triacontanol on Growth and Yield of Rice Plants:II. Effect of the triacontanol concentration
Effective concentration Foliar application Growth Rice plants Triacontanol Yield
2009/8/6
In the previous paper it was reported that the yield of rice was increased by the foliar application of triacontanol (TRIA) at early growth stages. However, as the range of TRIA concentration used was...
Male Sterility Caused by Cooling Treatment at the Young Microspore Stage in Rice Plants:XXXI. Four components participating in fertilization
Cooling injury Cooling tolerance Fertilization Microspore Pollen Rice
2009/8/5
We divided the developmental processes from microspore differentiation to fertilization into 4 phases and defined the component relating to fertilization in each phase. The percentage of fertilization...
A Basic Study on Field Experiment and Investigation Methods in Rice Plant:III. Precision of some sampling methods in sample survey of quantitative characters
Coefficient of variation Field experiment Quantitative character Rice plant Sampling method
2009/8/5
In sample survey on field experiment, samples have to be sampled at random in principle, but samples are often taken systematically due to restriction of time, labor and plot area. In order to get inf...
