| Pineapple blackheart disease is a physiological disease that is easy to occur in the process of post-harvest storage
and transportation of pineapple. Its shelf life is only 6-8 d, which seriously restricts the development of pineapple industry and
import-export trade. In this paper, the research status of pineapple blackheart disease in Bali in recent years is summarized from
three aspects: the pathogenesis, the pre-and post-harvest control methods, and the existing problems and the prospect. A series
of complex physiological and biochemical reaction processes are involved after the occurrence of pineapple blackheart disease.
The pathogenesis can be studied from the aspects of enzymatic browning, membrane lipid metabolism, sugar and acid metabolism,
active oxygen accumulation and etc. The control methods mainly include: cultivating Bali fruit in summer and resistant varieties
in winter, controlling the harvest time of Bali pineapple, air-conditioned preservation combined with low-temperature storage.
Comprehensive prevention and control of pineapple blackheart disease is required. A series of measures, such as improving
fruit quality, selecting resistant varieties and optimizing pre- and post-harvest treatments are taken to reduce the occurrence of
pineapple blackheart disease. The fundamental control of pineapple black heart disease lies in the improvement of varieties. With
the progress of gene editing technology and the maturity of pineapple genetic transformation system, Bali pineapple blackheart
disease will be eliminated fundamentally, which will greatly promote the development of pineapple industry in Leizhou Peninsula. |
