Stem Respiration of Rubber Tree of Different Strains and Different Girth
摘要
Abstract
[ Objective] To know the breathing of the different strains with different diameter circumference of the trunk of rubber tree. [Method] By using a LI-6400 portable CO2 analysis system,we investigated stem respiration of rubber trees with same diameter (50 ± 1 cm) of different strains (Reyan 7-33-97, PR1075Reyan 7-20-59) and the same strain (thermal 7-33-97) in different girth (50 ±1、60 ±1、70 ± 1、80 ± 1、90 ± 1、100 ± 1 cm) in China Academy of Tropical Agriculture, Danzhou City, Hainan Province. [ Result] Stem respiration of different girth and stains changed constantly with season, with a maximum value in August and the minimum value in January. Briefly, respiration rate in growing season was significantly higher than that of non-growing season. There was quite significant different annual average respiration rate between PR107(2.19 μmol/m2s) and the Reyan7-20-59 (1.91 μmol/m2s) ,and there was no significant difference between these two strains and Reyan 7-33-97 (2. 06 μmol/m2s). Diameter circumference was also an important factor to affect the rubber tree trunk breathing, the order from top to bottom of average annual respiration rate of Diameter circumference was followed as: 100 ± 1 cm(3. 36 μmol/m2s) >90 ± 1 cm (3.07 μmol/m2s) > 80 ± 1 cm (2.7 μmol/m2s) > 70 ± 1 cm (2.51 |μmol/m2s) > 60 ± 1 cm (2.38 μmol/m2s) > 50 ± 1 cm (2.06 μmol/m2s). [Conclusion] The same diameter of the different strains of stem respiration were different, the same strains of different diameter trunk breathing with diameter increased, the respiration also increased accordingly.关键词
