查询词典 weight

Tumorous stem yield was only significantly hereditarily positively correlated with vegetative duration, developmental duration, ratio of stem and leaf, horizontal length and whole plant fresh weight, negatively fur percentage and tumorous stem index. There were close relation and harmonies among the quantities characters that were significantly hereditarily correlated with tumorous stem yield. High yield breeding combining with strong ecological adaptability and good quality should be largely based on later maturity, tumorous stem diameter, whole plant weight and higher ratio of stem and leaf.
