lower concentrations produced better results even during the rainy season. In winter, the growth room ex-
periments showed better responses in the treatments with both IAA and NAA.
Vegetative propagation with various treatments with different growth regulators is based on bud
sprouting, leaf initiation, and inflorescence, as no root initiation was seen in mulberry, which showed only
callus formation. It could be concluded that summer and rainy seasons are not suitable at all, and so veg-
etative propagation of mulberry should be done only in the winter season.
