Royal Delicious was found statistically significant on par with other varieties. The maximum number of leaves was found in variety Royal Delicious i.e. 10.5 in 60DAG and 18.5 in 75DAG. Whereas, the minimum number of leaves was found in variety Fuji i.e. 8.83 in 60DAG and 16.33 in 75DAG.The effect of wrapping materials on the number of fully opened leaves was also found to be significantly different. The grafting tape-tied scion showed a higher number of leaves i.e. 10.42 in 60DAG and 18.25 in 75DAG compared to polyethylene plastic-tied scion i.e. 9.25 in 60DAG and 16.91 in 75DAG. The interaction between scion and wrapping material was found to be non-significant at both 60DAG and 75DAG.

The maximum sprout length was found to be 12.68 cm in Vance Delicious at 60DAG and 37.78 cm in Fuji variety at 75DAG. Fuji variety was found statistically significant with Vance Delicious i.e. 12.68 cm. Variety Royal Delicious showed minimum sprout length at both 60DAG and 75DAG i.e. 9.65 cm and 31.45 cm respectively. The result of ANOVA also showed the effect of wrapping materials on sprout length to be statistically non-significant. However, at 60DAG and 75DAG the sprout length was found to be 10.45 cm and 33.29 cm in graft tied with polyethylene plastic, and the sprout length of 11.62 cm and 33.79 cm in graft tied with grafting tape. The interaction between scion and wrapping material was found to be non-significant at both 60DAG and 75DAG. 2.4 Sprout girth increment The effect of scion variety and wrapping materials on sprout girth increment was found to be statistically non-significant in both observations i.e. 60DAG and 75DAG (Table 3). At 60DAG, the maximum sprout girth was found to be 1.36 cm on the Vance Delicious variety and the minimum sprout girth was found to be 1.25 cm on Red Chief. At 75DAG, the maximum sprout girth was found to be 1.59 cm on the Fuji variety and the minimum sprout girth was found to be 1.44 cm on the Vance Delicious variety. All the scion varieties were found to be statistically similar for sprout girth.
