Morphological diversity of mindi (Melia azedarach) from agroforestry system in North Sumatra, Indonesia

Abstract

Mindi (Melia azedarach) is a fast-growing woody plant with potential forcommunity forest development. Mindi wood is used to furniture material, parquet, fancy plywood, and fancy laminated veneer, and it is also exported. Although the communityforest in Deli Serdang Regency is established as a seed source for mindi in North Sumatra,information on its diversity is still lacking. The aim of this research was to get informationabout morphological differentiation of mindi in Deli Serdang Regency. Direct observationand measurement on morphological and growth character of mindi had been conducted inthree populations of community forest in Deli Serdang Regency. Those were Percut SeiTuan population, Biru-Biru population, and Pancur Batu population. The result showed thatof 19 observed morphological characters, there were two characters: number of leave andfruit weight able to differentiate the populations—individual tree from three populationclustering into three groups. The first cluster consists of 35 individual trees from Percut SeiTuan (7 trees), Biru-Biru (12 trees), and Pancur Batu (16 trees). The second cluster consistof 24 trees originated from Percut Sei Tuan (13 trees), Biru-Biru (8 trees), and Pancur Batu(3 trees). A third cluster consists of one tree from Pancur Batu.
