Other claims from this paper (9)
- Intervention effect Under high light intensity, total root length, root tips and root surface area of the two rice varieties first increased then decreased as nitrogen level rose.
- Intervention effect Under high light intensity, root volume, root dry weight and shoot dry weight of the two rice varieties first increased then decreased as nitrogen level rose.
- Intervention effect Under high light intensity, root/shoot ratio and total dry weight of the two rice varieties first increased then decreased as nitrogen level rose.
- Intervention effect Under low light, the root and dry weight indexes of Liangyoupei-9 changed with nitrogen level in the same way as under high light.
- Intervention effect Under low light, the root and dry weight indexes of Shanyou-63 dropped continuously with increasing nitrogen.
- Observation In V2, plant height under low light, and chlorophyll content and tiller number under high light, increased gradually.
- Observation Under high light, soluble sugar and soluble starch content of both rice varieties dropped gradually.
- Observation In V1, starch dropped first then increased under low light.
- Intervention effect All measured indexes except plant height were lower under low light than under high light.
