Abstract:

Three tapping time during the daytime of six rubber cultivars was set to explore the rubber yield, latex quality and raw rubber properties of different rubber varieties. The two-way analysis of variance showed that rubber production was significantly affected by the interaction between tapping time and rubber variety, and the response of each physiological parameter to the variety was significantly different, but there was no significant difference to the tapping time. The most suitable time for daytime rubber tapping is 6:00 am in the three daytime rubber tapping time treatment. Reken 524 and Reken 525 were the most suitable daytime rubber tapping variety judged by latex volume, dry rubber yield and physiological parameters. 7-33-97 and Reken 501 were the most suitable daytime rubber tapping variety judged by common raw latex properties. Considering the purpose of improving labor efficiency and increasing the income of rubber workers, Reken 524 and Reken 525 could be used for daytime rubber tapping at 6:00 am during the peak rubber production period in Maoming Reclamation Area, Guangdong, China.
