Overcoming the rot rate, increasing the number of shoots and shoot growth in Cayenne pineaple rapid multiplication by shoot and stem subdivisions NguyÔn ThÞ NhÉn1 Summary Cayenne pineple is characterized by high yield potential and therefore, it is now promoted to develop in Vietnam. To meet the requirements of vegetatively propagated materials for expanding the cultivation areas, the propagation of various methods have been studied. In this study, we have carried out some experiments on shoot and stem subdivisions in order to improve the efficiency of the proporation. The treatment with Benlat 0,3% decreased as the rot rate of the stem cutting by 50% in comparition with the control. Combination of αNAA + BA stimulated rapid growth and development of the shoots.
