Abstract:
Taking Polygonum viviparum seeds in Qilian county as test materials.The effect of different water initiation temperature and initiation time on the germination of Polygonum viviparum seeds was studied by using different water initiation temperature and initiation time,in order to provide reference for the research and application of seed initiation technology of Polygonum viviparum.The results showed that seed germination rate,germination potential,germination index,vigor index,seedling germ length and radicle length differed under the treatments of hydro-priming temperature and time,and the germination and seedling growth indexes of Polygonum viviparum seeds differed significantly (P<0.05) from those of 5 ℃ and 35 ℃ treatment when the hydro-priming temperature was 15 ℃ and 25 ℃,and the germination and seedling growth indexes of Polygonum viviparum seeds differed from those of the control group when the hydro-priming time was 24 hours.The comprehensive analysis of TOPSIS model showed that the treatment of hydro-priming temperature of 15 ℃ and time of 36 hours could significantly improve seed germination and seedling growth.In conclusion,the treatment of hydro-priming temperature of 15 ℃ and time of 36 hours was an ideal choice for seed germination and seedling growth of Polygonum viviparum.
