Abstract:
The seeds germination of ‘Houndog 6’,‘Cochies’,‘Starfire’ three tall fescue’s cultivars were researched under artificial drought stress by using different concentrations of polyethylene glycol (PEG6000) solution. The results showed that it had no significant difference among the time of three cultivars’ seed beginning to germinate under drought stress. But none of these three germinated at high PEG concentration. The seeds germination of ‘Houndog 6’ and ‘Starfire’ were promoted at low concentration. But at high concentration, the germination of three cultivars were all inhibited. The order of these three cultivars’ drought resistance was ‘Starfire’ >‘Houndog 6’> ‘Cochies’.
