PENGARUH KONDISI DAN PERIODE SIMPAN TERHADAP PERKECAMBAHAN BENIH CEMPAKA WASIAN (Magnolia tsiampaca (Miq.) Dandy

Abstract

Cempaka wasian ( Magnolia tsiampaca (Miq.) Dandy) is one of the most popular carpentry woods in North Sulawesi. The development of cempaka wasian species is constrained by the inability of seeds to be stored for a long period of time . The purpose of this research was to determine the effect of different storage periods and conditions towards seed germination of cempaka wasian. The experimental design used completely randomized factorial design with two main factors as follow: s torage c ondition and s tor a ge p eriod s . The results showed that the conditions and storage periods had an effect on seed water content, germination rate, and seed vigor index of cempaka wasian seeds, but it d id not affect the germination capacity . The storage conditions of air condition room (tempe r a t ur e 18oC ― 21oC, relative humidity 51 percent ― 61 percent ) was the most ideal condition for storing cempaka wasian seeds . Cempaka wasian seeds are included in the category of intermediate seed because the treatment of the storing period for 4 (four) weeks d id not affect the germination capacity even though the water content of the seeds has decreased.
