Abstract

Although the citrus rootstock, trifoliate orange, is disease and cold resistant and offers good fruit quality, it is affected more by zinc and iron deficiencies than some other rootstocks, according to this report from U.C., Los Angeles. Other nutrient disorders seem to result from high potassium and phosphorus conditions, low magnesium supplies and certain nitrogen levels.
