近年来不少研究报告指出,气候是影响某一品种果实品质及成熟期的诸因素中最重要的因素。本研究在加利福尼亚州的三大气候区选取四个柑桔产地,在同样栽培管理条件下,比较气候引起柑桔果实品质及成熟期的差异。四个果园是:文土腊郡的某农场(简写L),奥伦治郡的南海岸田间站(SC),这两处代表加州较冷凉的沿海谷地植物气候 In recent years, many studies have pointed out that climate is the most important factor affecting the quality and maturity of a variety of fruits. In this study, we selected four citrus producing areas in three major climatic zones of California. Under the same cultivation and management conditions, the differences in citrus fruit quality and maturity caused by comparative climate were studied. The four orchards are: a farm in Ventura County (short for L), the South Coast Field Station (OG) in Orange County, both of which represent plant climate in the cooler coastal valleys of California
