| Jeju-Do is a volcanic island of which climate is very warm and humid, but Opuntia lanceolata Haw, showing CAM metabolism is growing at Wolyung-Ri, Hanrim-Eup, Jeju-Do. Annual productivity of Opuntia was 696.47g/m2/yr and 533.47g/m2/yr at two populations on the seashore respectively and 414.92g/m2/yr on the basalt wall of a village. Stem area index was 13.74, 6.93, and 9.30 at each population which are higher values than average range of leaf area index. The standing crop was the highest at the second cladode from the cladode showed little difference at most chemical properties of P, K, Ca and Na. Total nitrogen contents were the most at the youngest cladode and the lest at the oldest one. Soils were infertile of which organic contents were 1.5% and 5.0% on the seaside and the basalt wall respectively. The soil on the basalt wall contained little water whose water contents were 0.9% and at seashore population 15.12% of water contents were. Furthermore high exchangeable Na contents in soil added waer deficiency. |
