修剪及外源调节剂对北美冬青"奥斯特"营养枝生长及株型的影响
Effects of Pruning and Exogenous Regulators on Vegetative Shoot Growth and Plant Type of Ilex verticillata"Oosterwijk"
摘要
Abstract
This study adopted single-factor and two-factor completely randomized block designs to explore the regulatory effects of different pruning methods,plant growth regulators(PGRs),and their combinations on the vegetative shoot growth and plant type of Ilex verticillata"Oosterwijk".The results indicated that pruning methods,plant growth regulators,and their interaction had extremely significant effects on all the measured indicators(P＜0.01).Among the single-factor pruning treatments,the medium pruning(retaining 1/2 of the total branch length)exhibited the optimal effect.For the single-factor regulator treatments,the applications of 6-BA at 200 mg·L-1 and 300 mg·L-1 showed remarkable performance.Comprehensively analyzed,the combination of medium pruning and 6-BA 200 mg·L-1 was identified as the optimal treatment.Under this treatment,the number of newly sprouted secondary shoots reached 11.2,the stem diameter was 7.3 mm,and the plant type compactness was 42.3％.This treatment could effectively meet the commercial cut-branch requirements of abundant branching,robust shoots,and compact plant type,providing theoretical basis and practical guidance for the standardized and commercialized production of high-quality cut branches of Ilex verticillata.关键词
