Effect of Chemical Reagent Treatment on Seed Germination of F.kryloviana and F.kirilowii
Festuca kryloviana and Festuca kirilowiiare new varieties of fine forage suitable for planting in the Qinghai-Tibet Plateau,and there are slow germination,low germination rate and irregular seedling emergence in the process of popularization and planting.Two kinds of fescue seeds were used as experimental materialsto study the effects of different chemical reagents(10%NaOH,2%KNO3,0.5%KMnO4)on the germination by using the method of germination on petri dish paper.The germination rate,germination potential,germination index,vitality index,radicle length and seedling length were measured and analyzed.The results showed that:1.10%NaOH soaking has a significant inhibitory effect on the germination of the two fescue species.2.0.5%KMnO4 soaking could promote the germination of two fescue seeds;3.2%KNO3 soaking had a significant effect on the germination index and morphological characteristics of the two fescue seeds,and the comprehensive evaluation with membership value was the best.
