两株植物促生细菌对金丝皇菊生长发育的调控效应及其菌肥应用潜力
Regulatory Effects of Two Strains of Plant Growth-Promoting Bacteria on the Growth and Development of Chrysanthemum morifolium'Jinsi Huangju'and Their Potential Application as Biofertilizers
摘要
Abstract
[Objective]To address the growth constraints of chrysanthemums under conventional culti-vation conditions,this study applied two strains of plant growth-promoting bacteria,isolated in-house,to Chrysanthemum morifolium'Jinsi Huangju'.The aim was to investigate their regulatory effects on plant growth and development,thereby exploring green microbial solutions for enhancing the growth of Chrysan-themum morifolium'Jinsi Huangju'from the perspective of microbial improvement.[Method]During the seedling stage,washed endophytic bacterial strains were applied via root drenching(20 mL per plant).Morphological growth and flowering traits were observed 70 days after treatment.[Result]The inoculation of both bacteria strains positively affected the vegetative growth of Chrysanthemum morifolium'Jinsi Huangju'.After 70 days,plants inoculated with strain NHH1-1 exhibited a significant 32.1%increase in plant height and a highly significant 76.7%increase in crown spread;plants inoculated with strain NHB2-5 showed a significant 37.7%increase in plant height and a significant 90.7%increase in crown spread.Both treatments promoted flower bud formation(7～9 buds per plant).The flower opening rate reached 44.44%in the NHB2-5 treatment and 14.29%in the NHH1-1 treatment.Furthermore,the ap-plication of both strains significantly increased the number of adventitious buds and enhanced their height and the basal stem thickness of'Jinsi Huangju'.[Conclusion]The application of both strains of plant growth-promoting bacteria significantly enhanced the growth and flowering of Chrysanthemum morifolium'Jinsi Huangju'.Specifically,strain NHH1-1 primarily promoted vegetative growth and bud formation,whereas strain NHB2-5 demonstrated a comprehensive promoting effect on vegetative growth,flower num-ber,and lateral bud development.The results indicate that both strains can effectively improve the growth and development of'Jinsi Huangju'and possess promising potential for practical application.关键词
