Abstract:

In this paper,studies on tissue culture and grafting of vegetable motong in seedless watermelon are carried though. The results showed that different disinfectors have definite effectson bourgeonof watermelon embryo.In which,disinfectorof Chlorine Dioxide (250 mg/L)usedto treat watermelon embryo have advantages in germinationof watermelon embryo.The most ouitable mediumf or buds induetion from eotyledon of Citrulluslanatus was 1/2MS +IAA0.2 mg/L+sucrose 30g/L + agar 7g/L;Different consistencies of incretionhave also definite effects on multiplication of acervate buds ,and the succeedculture medium of MS +6-6-BA0.44 mg/L +IAA0.2 mg/L + sucrose 30g/L +agar 7g/L can obstain the most multiplicating rate;The result of studyon different consistencies of NAA in rooting of single bud showed that the culture medium of MS+NAA0.5 mg/L have th emost rooting rate(96. 2%).
