Other claims from this paper (7)
- Intervention effect When the husk is not closed to a certain degree, 1000-grain weight decreases.
- Intervention effect With less husk closing, the normal seedling percentage is low.
- Intervention effect With less husk closing, resistance to ageing is lower.
- Intervention effect With low husk closing, the amount of embryos of decreased vitality increases greatly.
- Intervention effect In vacuum condition, the effect of husk closing degree on resistance to ageing decreased.
- Mechanism A main factor of husk closing degree affecting resistance to ageing is husk decreasing seed oxygenizing.
- Method / resource Artificial ageing at 100% relative humidity and 40 ℃ for 5 days gives an ageing degree equal to one summer of natural temperature ageing.
