难溶性无机磷酸盐对大豆苗期根系生长的影响
Effect of Insoluble Inorganic Phosphate on Root Growth of Soybean Seedlings
摘要
Abstract
Based on previous field experiment,two P-efficient soybean genotypes(Dongnong44 and Dongda l)and two P-inef ficient soybean genotypes ( Heihe 13 and Heihe 24) were selected as materials to investigate the relationship between root growth and insoluble phosphate using sand culture and water culture. The results showed that there was significant difference a mong the ability to use insoluble phosphate for the four soybean genotypes. Compared with control, under the condition of A1-P, Ca-P and Fe-P treatment,the root dry weight,the root/shoot ratio,total length and surface area per plant of root system for the four soybean genotypes increased evidently,while the root P concentration,root P uptake and average root radius all decreased. Under different treatment, the root length and surface area of P-efficient soybean genotypes was greater than that of P-inefficient soybean genotypes, but the adaptability of some traits in P-efficient soybean genotypes did not had advantages.关键词
