青霉素对樱桃离体培养试管苗生长及抑菌作用的研究

STUDIES ON THE EFFECT OF PENICILLIN ON THE GROWTH OF CHERRY PLANTLETS AND BACTERIOSTASIS IN VITRO

在樱桃离体培养中，于ｃｏｌｔ砧木试管苗生长和生根培养基添加１００～５００×１０－６ｍｇ／Ｌ的青霉素，其对试管苗有不同程度的促进生长和生根作用；２００～５００×１０－６ｍｇ／Ｌ的青霉素，对污染试管苗的细菌有不同程度的抑制和消除作用，但对霉菌无效．

In the course of isolated culture,colt stock plantlets when growing and the medium of branch root are added 100～500 ×10 -6 mg/L with penicillin.Results:the penicillin can accelerate the growing and the rooting of plantlets.That 200～500×10 -6 mg/L penicillin is used to dispose of polluted plantlets will restrain and even eliminate bacteria infection,but it will do no good to molds.
