极度稀植条件下菊芋株高与其生物学特性相关性研究
The Study on Relationship Between Height and Quantitative Traits of Helianthus Tuberous L
摘要
Abstract
The maximum density was used in the experiment to study the influence of height on leaf number, floret number, tuber number, leaf biomass, tuber biomass, stem biomass and root biomass etc. To provide a reference for se-lecting new breeding and cultivating management of HelianthustuberousL.. In this research 56%of Helianthustuber-ous L. height concentrated in the 200-241cm under the condition of maximum density planting;The tuber’s number and the tuber, root, floret, underground biomass were gradually increased with the increasing of the plant height;The re-lationship between height and other factors indicated positive correlation, and the relationship with stem biomass and the aboveground biomass was significantly(P<0.01);The relationship between height and other factors was negative correlation when the height of HelianthustuberousL. is less than 200cm, and the relationship with stem biomass, tuber biomass and underground biomass was significantly(P<0.01).关键词
