Other claims from this paper (10)
- Association In the 'World-star' variety, shoot fresh and dry weights were significantly higher than in 'Sushiro'.
- Association In the 'World-star' variety, leaf number and leaf area were significantly higher than in 'Sushiro'.
- Intervention effect Under mixed light (RB) and red light (R), the 'Worldstar' variety had 35% higher shoot dry weight than under blue (B) and white (W) light at 25 DAT.
- Intervention effect In the 'Sushiro' variety, mixed light (RB), which gave the highest shoot fresh and dry weights, gave 40% higher shoot fresh and dry weights than white light (W).
- Observation Both cultivars showed leaf epinasty at 21 DAT only under mixed light (RB) and red light (R).
- Intervention effect Red light (R) caused significantly more epinasty symptom than mixed light (RB).
- Association The authors interpret leaf epinasty as associated with red light.
- Intervention effect Under red light (R), cell density at the leaf edge was lower than at the leaf center.
- Recommendation The authors recommend identifying the appropriate mixing ratio of the two light sources.
- Recommendation The authors suggest the 'Worldstar' variety is more suitable for plant factory cultivation under LED light.
