Abstract

ABSTRACTCempaka wasian (Magnolia tsiampaca (Miq) Dandy) is a forest tree species that has recalcitrant seed character. Recalcitrant seeds are difficult to be stored for a long period, thus storing the seedlings can be considered as an option. This research aims to determine the effect of growth inhibitors and planting media on seedling growth during storage. The inhibitors used were paclobutrazol 250 ppm, NaCl 0,5% and aquadest (as control treatment). The media used consisted of top soil+cocopeat (1:1), top soil+sand(1:1) and top soil+husk charcoal (1:1). The research design used was a complete randomized factorial pattern design. The results showed that the inhibitors had a significant effect on the growth os seedling height. Provision of 250 ppm paclobutrazol was able to inhibit the growth of seedling height. Planting media also had a significant effect on the growth of height and diameter of the seedlings, also on seed quality index of cempaka wasian. The soil+cocopeat and soil+sand planting media are effective to reduce the growth rate in both height and diameter of cempaka wasian seedlings during storage. Key words: Cempaka, growth inhibitors, planting media, seedling ABSTRAKCempaka wasian (Magnolia tsiampaca (Miq) Dandy) adalah salah satu jenis pohon hutan yang memiliki karakter benih rekalsitran yang sulit disimpan dalam jangka waktu lama, sehingga perlu dilakukan penyimpanan dalam bentuk semai dengan menggunakan bahan semai. Tujuan penelitian ini adalah untuk mengetahui pengaruh bahan penghambat pertumbuhan dan media tanam terhadap pertumbuhan semai cempaka wasian selama masa penyimpanan. Bahan penghambat pertumbuhan yang digunakan adalah paklobutrazol 250 ppm, NaCl 0,5%, dan akuades sebagai kontrol. Media tanam terdiri dari tanah+cocopeat (1:1), tanah+pasir (1:1), dan tanah+arang sekam (1:1). Rancangan percobaan yang digunakan adalah rancangan acak lengkap pola faktorial. Hasil penelitian menunjukkan faktor zat penghambat tumbuh memberikan pengaruh yang nyata terhadap pertumbuhan tinggi bibit. Pemberian paklubutrazol 250 ppm mampu menghambat pertumbuhan tinggi bibit. Faktor media tanam memberikan pengaruh nyata terhadap pertumbuhan tinggi, diameter, dan indeks mutu bibit cempaka wasian. Media tanam tanah+sabut kelapa dan tanah+pasir merupakan media yang efektif mengurangi kecepatan pertumbuhan tinggi dan diameter semai cempaka wasian selama penyimpanan.Kata kunci: Cempaka, bahan penghambat pertumbuhan, media tanam, semai

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: storage condition and storage periods. 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 did not affect the germination capacity. The storage conditions of air condition room (temperature 18ºC―21ºC, relative humidity 51percent―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 did not affect the germination capacity even though the water content of the seeds has decreased.

Abstract

Obstace of pakoba (Syzygium luzonense (Merr.) Merr.) cultivation in nursery is  twig caterpillar (Hyposidra talaca WLK) attacks. The Pest symptoms was holes in the leaves especially young leaves; twig caterpillar enable to attack all leaves of pakoba seed. Severe attacks cause death of seedlings. There are five blocks in pakoba nursery that were observed; 1014 pakoba seedlings were grown in these blocks. The average percentage of twig caterpillar’s attack was quite high, reached 49.34%. Twig caterpillar has been controlled by integrated pest management. Chemical control to decrease twig caterpillars attack in nursery has been done by using half dose of insecticide profenofos.
