Growth Performance of Different Mango (Mangifera indica L.) Varieties as Rootstock for Harumanis Planting Material Production

Abstract

Mango (Mangifera indica L.) is one of the important crops cultivated in Malaysia. The purpose of this experiment was to evaluate the germination and the growth of selected seedlings from commercially significant mango varieties such as Chokanan, Sala, Harumanis and Masmuda, and also non-commercially significant varieties namely Telur and Epal. The six tested rootstocks were studied for their effect on grafting success, survival and takes growth of Harumanis variety. The results indicated that Telur scored the highest germination percentage with 74.64%, while Harumanis scored the least germination of 30.76%. A maximum stem diameter was observed in Chokanan rootstocks at 13.41 mm, while the minimum value was observed in Harumanis rootstocks with 9.68 mm. For internodes length, Sala had the longest internode with 12.48 cm, while Epal had the shortest with 8.53 cm with the difference of 31.65%. For grafting performance, all tested rootstocks exhibited 100% success (30 days after grafting, DAG) and survival (60 DAG) when grafted with Harumanis scion, with the exception of Sala with 85% survival. At 21 DAG, Telur was observed to have the maximum bud sprouting with 85% while Sala produced the minimum with 30%. For scion growth, Harumanis rootstocks showed the maximum value in terms of scion length and diameter, while Masmuda produced the shortest.
