CVPDr DNA FRAGMENT AFFECT DIFFERENCES IN RESISTANT TO CITRUS VEIN PHLOEM DEGENERATION (CVPD) DISEASE, NUTRIENT DEFICIENCIES AND QUALITY OF FRUITS

Abstract

Citrus Vein Phloem Degeneration (CVPD) disease is a major obstacle in the effort to develop and increase the production of citrus fruits in Bali. The study on the polymorphism of CVPDr DNA fragment shows that the CVPDr DNA fragment is resistant factor againt CVPD disease. This study try to elaborate the difference in resistance led to differences in plant nutrients deficiencies in the citrus plant with CVPD disease. . Besides, there are also difference in the quality of fruit due to CVPD disease attacks such as water content, vitamin C content and antioxidants in citrus fruits, color, flavor, taste and texture and fruit into small, hard and sour taste.

“…Citrus greening disease (CGD) is a disease that attacks mandarin plants and has become a serious threat to mandarin production in every country (Batool et al 2007). Citrus Vein Phloem Degeneration (CVPD) disease is a major cause of low productivity among mandarin plants (Yuniti et al 2017). Decaying stems can also become obstacles to efforts to increase the citrus productivity during pre-and post-harvest periods, causing spots around stem area to become firm and dry, while the fruit skin softens and rots (Kaur et al 2007).…”
