问荆化感作用对大豆生殖后期形态、生理和产量性状的影响
Effect of Allelopathy of EquisetumarvenseL. on Morphology, Physiology and Yield Traits of Soybean in Postreproductive Period
摘要
Abstract
Our objective was to discuss the allelopathy of Equisetum arvense L. on soybean at postreproductive growth. The greenhouse pot experiments were performed to investigate the effect of E. Arvense sterile shoots aqueous extract on morphological indices, physiological indices and yield trait of 5 kinds of soybeans, i.e., BD, BJ, DK1, DK3 and HH in postreproductive period. The results showed that plant height, leaf area, chlorophyll content, grain number per plant, pod number per plant, effective pod number per plant and podding height of all kinds of soybean decreased, POD activity and CAT activity firstly increased and then decreased with E. arvense aqueous extract treatment. The plant height in yield trait of BJ significantly decreased with the treatments of E. arvense aqueous extract at 0.04 kg/L and 0.07 kg/L concentration (P<0.05). The pitch number of BD significantly decreased with the treatments of E. arvense aqueous extract at 0.07 kg/L concentration (P<0.05). However plant height in yield trait of BD, DK1, DK3, HH and pitch number of BJ, DK1, DK3, HH changed little after the treatment of E. arvense aqueous extract. All of above indicated that soybean had certain resistance with the treatments of E. arvense aqueous extract at lower concentration, while there was great influence of the allelopathy of E. arvense on soybean at postreproductive growth.关键词
