Ecological effect and the utilization rate of K nutrient for different K use efficiency cotton genotypes
IPNI-2010-CHN-HB37
Potassium (K) plays a vital role in plant physiological and biochemical processes. K is important in cotton growth as it influences cell division and photosynthesis - formation of carbohydrates, translocation of sugars, mineral nutrients and photosynthesis matter. Read more
Interpretive Summary
This project was implemented by Huazhong Agricultural University. It is important to identify cotton genotypes with higher nutrient efficiency and understand the mechanisms of response to K deficiency among genotypes to help in breeding high K efficiency genotypes. We selected a high K use efficiency genotype 103 and a low K use efficiency genotype 122 from 86 varieties and four different families in the last five years.
To identify genotypes with higher K efficiency and understand the mechanism of differences in response to K deficiency among genotypes, a pot culture experiment was conducted in the greenhouse of the College of Resources and Environment of Huazhong Agricultural University from May 7 to October 15, 2011. Study on the effect of dry matter and K distribution and accumulation between 2 different cotton genotypes (high and low K-use efficiency) was conducted with grafting technology.
