| Abstract: | Biological characteristics of four indraught Brazil upland rice varieties and one three-line hybrid combinations under dry-cultivation were studied. The results showed: Tangara and Iapar-9 were fit to cultivation in Changsha area. Their individal plant type were better and growth period were moderate. The yield of Tangara was the highest among the experimental varieties and combinations, rice hybrid rice combinations Xinxiangyou 80 was the second; Root activity of Tangara was the biggest. Photosynthesis rate, transpiration rate and stomatal conductance of Xinxiangyou 80 were all higher than those of upland rice varieties, and those of Tangara were higher than other upland rice varieties. |
