Research On Rwc Variation Regularity Of 'Jinhuang' Mango (Mangifera Indica L)

The relative Water Content (RWC) variations of mango cultivars "Jinhuang" were researched in Hainan, China in order to provide rationale for water integrated management of mango cultivation. The results show that RWC variation of "Jinhuang" mango is different during one year, and RWC variation is also different during one month. RWC variation of mango cultivars "Jinhuang" in some months appeared obviously "day break". Before harvest, irrigation should be properly controlled as well to reduce cracking, promote coloring and extend the shelf life after harvesting. After retraction, water should be complemented as quickly as possible to benefit the sprout and send forth new branches. Therefore, water requirement of different phenological periods and seasons can be adjusted.
