Abstract
Conventionally sugarcane propagation using bud setts takes a longer time. Consequently variety utilization period is limited because of clonal degeneration. A study was therefore undertaken to speed up the distribution of planting materials by using “stratified rayungan” method. The results of the study revealed that the sprouted buds from the stump with 9–14 and 15–20 bud positions were faster than that of 9–20 bud position. At 3 and 4 months after planting, the total number of shoots from stump with 9–14 and 15–20 bud positions was greater than that of 9–20 bud position. PS 851 variety produced more shoots than PSJT 941, however, the performance of PSJT 941 shoots was better than that of PS 851. The effect of IAA was better than that of root stimulant, while PSJT 941 showed better response to rooting stimulant than PS 851. The period of storage significantly influenced the percentage of fresh seedlings. Viability more than 80 % was found from rayungan seedlings having 4 leaves for PSJT 941 and 5 leaves for PS 851. Application of rooting stimulant was needed to speed up root growth and enhanced viability for the seedlings having 3 or 4 leaves. The distribution of rayungan planting materials to another sugarcane area for 3 days is still feasible.
