Other claims from this paper (19)
- Intervention effect Optimum growth of Alnus glutinosa occurred in plants grown in full sun.
- Intervention effect Acetylene reduction rates of Alnus glutinosa were maximum in full sun.
- Association Acetylene reduction rates of Alnus glutinosa were highly correlated with chlorophyll content per unit leaf area, specific leaf weight and nodule starch content.
- Intervention effect Number and fresh weight of nodules of Alnus glutinosa were higher in full-sun-grown plants than at other light intensities.
- Intervention effect Total N content of Alnus glutinosa plants was higher in full-sun-grown plants than at other light intensities.
- Intervention effect Optimum growth of Myrica pensylvanica occurred in plants grown under 70% light intensity.
- Intervention effect Myrica pensylvanica plants at 70% light had more chlorophyll per unit leaf area than plants grown in full sun.
- Intervention effect Myrica pensylvanica plants at 70% light had fewer leaves than plants grown in full sun.
- Intervention effect Acetylene reduction rates of Myrica pensylvanica were maximum at 70% light.
- Intervention effect Reducing and non-reducing sugars in the nodules of Myrica pensylvanica increased with increased light intensity.
- Intervention effect Fresh weight of nodules of Myrica pensylvanica was not affected by light.
- Intervention effect Optimum shoot/root ratio of Elaeagnus umbellata occurred in plants grown under 70% light.
- Intervention effect Acetylene reduction rates of Elaeagnus umbellata were maximum in full sun.
- Association Acetylene reduction rates of Elaeagnus umbellata were correlated with non-reducing sugars content in the nodules.
- Intervention effect Elaeagnus umbellata plants grown under light had higher N content than plants grown in other treatments.
- Intervention effect Optimum growth of Elaeagnus angustifolia occurred towards high light intensities.
- Intervention effect Elaeagnus angustifolia had maximum acetylene reduction rates and highest N content under full sun.
- Intervention effect Number and fresh weight of nodules of Elaeagnus angustifolia were not affected by light intensity.
- Mechanism Supply of photosynthates through light intensity appeared to regulate nitrogen fixation rates, which in turn affected growth in most of the species studied.
