Abstract：To explore the effects of seeds with different sizes on the emergence and growth of seedlings in fresh waxy maize,the Suyunuo 11 was used as the material in the study.The tested seeds were divided into three grades:large,medium and small through vibrating sieves with different pore sizes,and the effects of seed size on the emergence rate,emergence index,vigor index,plant height,stem diameter and dry matter accumulation were investigated.The results showed that compared with small-sized seeds(T3),the emergence rate of large-sized(T1)and medium-sized seeds(T2)were 31.7%and 26.4%higher respectively,the emergence indices were 55.9%and 34.1%higher respectively,vigor index I were 130.6%and 85.8%higher respectively,and vigor index II were 197.3%and 114.3%higher respectively.In term of dry matter accumulation of seedlings,the fresh weights of roots of large-sized(T1)and medium-sized(T2)seeds were 57.9%and 37.9%higher than those of small-sized seeds(T3)respectively,the fresh weights of above-ground parts were 56.7%and 42.1%higher respectively,and the total fresh weights of plants were 48.1%and 23.9%higher respectively.This study showed that seeds should be graded before sowing waxy maize,and larger seeds should be preferentially selected to improve the emergence rate and seedling uniformity.
