Pengaruh Panjang dan Lama Masa Simpan Entres terhadap Pertumbuhan dan Keberhasilan Sambung Pucuk Tanaman Mangga (Mangifera indica L.)

Abstrak

Mango (Mangifera indica L.) is an important horticultural commodity whose quality seedling production relies mainly on top grafting. Limited availability of mother trees often requires scion transport and storage before grafting, making scion length and storage duration critical factors. This study investigated the effects of scion length, storage duration, and their interaction on plant height increment, leaf number increment, and seedling establishment percentage in mango top grafting. The experiment was conducted from February to April 2025 at Rizky Alam Borneo Nursery, Pontianak, using a 3×3 factorial Randomized Complete Block Design with three replications. Scion length was set at three levels (10, 15, and 20 cm) and storage duration at three levels (2, 4, and 6 days) using newspaper wrapping. Results showed highly significant interactions (P<0.01) between scion length and storage duration for all three parameters. The p₂l₂ combination (15 cm scion, 4 days storage) produced the highest height increment (6.44 cm), while p₂l₁ (15 cm, 2 days) yielded the most leaves (6.11 leaves). The p₁l₃ combination (10 cm, 6 days) resulted in the lowest seedling establishment percentage (2.00). Neither scion length nor storage duration significantly affected scion mortality or dormancy rates.
