Respon Pertumbuhan Bibit Wani Tanpa Biji (Mangifera caesia Jack var. Ngumpen Bali) pada Berbagai Komposisi Media Tumbuh

ABSTRACT Seedless Wani is one of the superior local fruit germplasm. It has specific character due to seedlessness, thickness of edible pulp (aril) and fruit flavors preferred by consumers for sweet, delicious taste, and specific flavor. Demand of seedless wani seedling is very high, but it cannot be fulfilled because of the method/technique of effective propagation is unknown. Although called seedless wani but about 10% of its total fruit have seeds, and progenies derived from those seeds genetically similar to its parent. This study was aimed to determine the best growing media composition on the growth of seedlings seedless Wani. This study was a pot experiment and used a randomized block design (RBD). The treatments tested were growing medium, consistins of four types i.e. mixture of soil + sand + organic matter (v:v:v = 6:0:0), mixture of soil + sand + organic matter (v:v:v = 3:2:1), mixture of soil + sand + organic matter (v:v:v = 3:1:2), and mixture of soil + sand + organic matter (v:v:v = 2:3:1). The results showed that the composition of the growth media mixture of soil + sand + organic matter (v:v:v = 3:1:2) gave better seedling growth (height, leaf number, and stem diameter) compared with other growing media. Based on these results, it is suggested to use composition of growing media mixture of soil + sand + organic matter (v:v:v = 3:1:2) for propagation seedless Wani.
