Collapse of ‘Murcott’ Tangerine Trees1

Year: 1976

Type: article

Abstract: ‘Murcott’ tangerine ( Citrus hybrid) trees often decline suddenly during fall and winter, if they are heavily loaded with fruit. First symptoms are wilt, yellowing of leaves, defoliation, and shriveling of fruit. The rapid loss of leaves and fruit, followed by dying back of branches, gives the appearance of death. However, such trees generally recover. The remaining leaves are deficient in one or more minerals such as N, P, K, or Mn. However, extra fertilizer does not prevent tree collapse. Seasonal studies showed that starch depletion and death of feeder roots accompany the decline. Root starvation, as a result of crop strain, appears to be the primary cause of rapid tree collapse.
