Flower morphology and inflorescence of Andaliman (Zanthoxylum acanthopodium DC.) from Dairi, North Sumatera

Abstract

Andaliman (Zanthoxylum acanthopodium DC.) is a spice plant typical of North Sumatra. Biological information on andaliman flowers is still limited. Therefore, the purpose of this observation is to study morphology of andaliman flowers and inflorescence arrangements that can be useful in understanding andaliman flower biology. The research was conducted on plants in one of the centres of andaliman production in Dairi District. Flower of andaliman is axilliary inflorescence, determinate flowers, dichasium, generally glomerate, the number of flowers in one peduncle varies greatly. The time blooming of the flowers in each rachis is quite varied. Flower andaliman small and hermaphrodite with its parts, sepals 5-7 free, pale yellow colour, 5-6 stamens, anther is reddish, pollen sticky, and 3-4 pistils, and sometimes 5 pistils, apocarps. Information obtained from this study can be used in subsequent studies related to pollination, fertilization, fruit set, and seed set. The variation of flower blossom in one peduncle is one of the factors contributing to the maturity of the fruit as a source of seed should be studied.

“…Permasalahan yang dihadapi dalam upaya perbanyakan andaliman secara generatif adalah daya kecambah biji yang rendah (Siregar 2003). Pada penelitian Siregar (2013) biji andaliman tanpa perlakuan memiliki persentase perkecambahan 30% pada 100 hari setelah tanam. Perkecambahan yang rendah dan umur berkecambah yang relatif lama disebabkan oleh struktur kulit biji yang keras.…”

This plant is grown wildly in the conservation area of Toba geopark and Tapanuli in North Sumatera Province [3][4][5]. Initially, it grows wildly in the forest surrounding the Lake Toba area.…”

Andaliman development as a regional superior product in Toba district North Sumatra Province based on regional innovation system

“…Andaliman is a typical plant of North Sumatra and is closely related to the life of the Batak people who live around the Lake Toba area. Andaliman is included in the type of spice with the Latin name Zanthoxylum acanthopodium DC and is a superior commodity in the Lake Toba area [1] [2]. Andaliman seeds are commonly used in various traditional Batak dishes such as arsik, natinombur, naniura and sambal Tuktuk [3].…”

“…This condition is due to the IOP Publishing doi:10.1088/1755-1315/1183/1/012098 2 tough structure of the seed coat which prevents the imbibition of water and gas exchange in the germination process. The majority of Andaliman grown in North Sumatra grows naturally from seeds dispersed by birds, as well as seeds obtained by farmers accidentally from burning weeds in areas of mature plants [2].…”
