The yield components and grain filling characters of northern large panicle type super japonica hybrid rice Liaoyou 3072 were studied.

6, Shan229, Xinong2208, Aifeng 3 and Sangl 88) were used as indicating crops to study the grain filling characters and matter translocation efficiencies on two nitrogen application rate(0,90kgN/hm2) .

In order to understand the effect of variety, sowing date and planting density on grain filling characteristics and yield of wheat varieties with different qualities, field experiments were carried out at the Experimental Farm of Wheat Research Institute of Shanxi Agricultural Sciences Academy during 2003~2005.

\'Jin-kai 2\' was used to study the effects of six kinds of planting densities on agronomic traits, filling characteristics, photosynthetic and yield characteristics of maize with whole covering on double ridges and planting in catchment furrows , which can provide high-yielding cultivation theory of maize with whole covering on double ridges and planting in catchment furrows .

Relationship of Grain Filling Characteristics and Endogenous Hormones Content of Winter Wheat (Triticum aestivum L.) Cultivars with Different Canopy Temperature Character in Filling Stage;

Effect of dry cultivation of Shanyou 63 on the grain filling characteristics and dry matter accumulation;

Comparison of grain filling characteristics of various rice varieties(combinations)

While the fundamental reason of effects is that average grain filling speed,especially the maximal grain filling speed and grain filling intensity of slow increasing period changes greatly.

In order to understand the mechanism of water saving and high yield cultivation of winter wheat, this research was concentrated on the carbon and nitrogen remobilization, the process of grain filling, the differentiation of endosperm cell, the metabolism of the starch and activities of the key enzymes relative to the sucrose biosynthesis.
