为研究不同密度下温室番茄的生长行为,对结构功能模型GreenLab进行改进,在提高拟合度的基础上,获得不同密度下番茄生长参数,通过参数分析将环境与番茄植株生长行为相联系。结果表明密度影响同化物产生与分配,通过外在形态,如出叶速率、叶厚、坐果率等表现,GreenLab模型可以重建这种生长行为变化。
This study investigated the effects of planting density, container size and period of raising seedlings on the growth and flowering of non-pinched snapdragons. In experiment 1, seeds were sown in July...
Effects of planting density on nitrogen fixation activity (acetylene reduction activity, ARA), yield and yield components of soybeans (Glycine max (L.) Merr.) were evaluated in the field experiment c...
To clarify the influence of planting density on podding of soybeans, field experiment was conducted in terms of the identification of the raceme order (RO). Soybean cultivars 'Tatisuzunari' and 'Tamah...
This study was carried out to examine the effects of planting density and planting patterns in reference to various characteristics at the panicle formation, heading and maturing stages in rice plants...
The influence of planting density on root growth and its relationship to leaf and tuber growth were investigated with two maincrop varieties in the potato. Three levels of planting density were exami...
The number and development of spikelets on a panicle directly affect the grain yield. In this study, we examined the differences among various rice cultivars in the number of spikelets per panicle (NS...
Field experiments were carried out in 2001 and 2002 to examine the lodging-resistance characteristics of various rice cultivars bred for the Tohoku region of Japan including the widely-cultivated cult...
Experiments were carried out in 1999, 2000 and 2001 on the field of Iwate University, Japan to examine the effect of nitrogen-free basal dressing accompanied with sparse planting density (BNo) on the ...
Grain yield of rice plants is composed of different yield components that vary with the genotype, environmental condition and cultivation practice. Experiments were conducted in 1999, 2000 and 2001 in...
At present, the main challenge in rice production is to achieve a high and stable yield with low input. In this study, the growth of tillers and yield of 12 rice cultivars and lines in the practice of...
Effects of planting density on the formation of the root system and the relative growth of the top and root in rice plants were investigated. The four planting densities used were 45, 70, 95 and 120 h...
The effect of planting density on grain yield and water productivity was evaluated in rice (Oryza sativa L.) grown in non-flooded lowland fields in Japan in comparison with flooded fields. One rice cu...
To establish a cultural technique for commercial production of a new high yielding variety of Chinese yam (D.opposita Thunb.) "Shintanmaru", we examined the effects of seed rhizophore weight and plant...
Dense planting is an important cultural technique to increase the number of spikelets per unit area, and is thought to be favorable for grain filling because it increases the percentage of spikelets o...
