Abstract
|
|
|
|
The contents of plastids, proline, protein, and polyamines were investigated in aloes (Aloe arborescence Mill, Aloe saponaria Haw, and Aloe vera L.) which were grown in field and shade culture for 20 days. Aloes grown in the field (80,000-100,000 ㏓) synthesized more chlorophyll, anthocyanin, carotenoid than those of shade treatment (10,000-15,000 ㏓) for 20 days. The proline content was increased in Aloe arborescence (27%), Aloe saponaria (45%), and then 20% and 27% of protein synthesis increased in the field, respectively, as compared to shade culture, which Aloe vera showed almost the same amount of proline, protein, and polyamine contents between the Field and shade culture. In the field, 17.6% and 13.4% of polyamine levels increased in Aloe saponaria and Aloe arborescence as compared to shade culture. It is suggested that the physiological responses of these accumulations of plastid, protein, and polyamine in Aloe saponaria and Aloe arborescence of the field may be the metabolic adaptation to high light intensity. As a results, this study indicated that Aloe vera is effective in the field culture. Aloe saponaria and Aloe arborescence are appeared effective in the shade culture.
