Abstract
Results 0f previous investigations on the effects of endogenous soluble carbohydrate and indolebutyric acid (IBA) (Thimba and Itulya, 1982a and b) prompted the present investigations to find out the relationship between IBA treatments and the endogenous soluble carbohydrate in different cutting t}'1pes of Passiflora edulis forma edulis Sims and their effect on rooting. Indolebutyric acid applied in four levels .of 0, 1000, 3000 and 8000 ppm to each of five cutting types namely terminal cutting, second cutting from the terminal, third cutting from the terminal, basal cutting and decapitated terminal cutting showed that the 3000 ppm application was the optimal level for all cutting types except the tenninal decapitated cuttings which were unresponsive. The lowest soluble carbohydrate level was recorded at 3000 ppm of IBA while 1000, 8000 and 0 ppm of IBA treatments had higher levels in that order. These levels seemed to be inversely related to percentage rooting, number of roots and root dry weight per cutting produced in each hormone treatment. Significant interactions were noted between the length of time from planting and the cutting types, and IBA and the cutting types. Significant negative correlations (r) were noted between endogenous soluble carbohydrate and number of roots/cutting, root dry weight/cutting.
