Kajian Pengusangan Cepat dan Penyimpanan Biji terhadap Perkecambahan Anaphalis longifolia (Blume) Blume ex.DC.

Abstract

Anaphalis longifolia merupakan kelompok bunga edelweiss yang memiliki nilai konservasi tinggi, namun upaya konservasi melalui kegiatan penyimpanan biji dan pengembangan usaha pembudidayaannya relatif masih terbatas. Penelitian ini melaporkan hasil dua percobaan yang dilaksanakan di laboratorium Kebun Raya Cibodas. Dalam percobaan pertama, pengusangan biji dilakukan menggunakan etanol 96% dengan 11 lama waktu perendaman (0, 10, 20, 30, 40, 50, 60, 70, 80, 90 dan 100 menit), sedangkan dalam percobaan kedua dilakukan pengujian kualitas daya simpan biji terhadap beberapa tempat penyimpanan seperti desikator, lemari, kulkas 4 oC dan freezer -20 oC selama kurun waktu 12 bulan. Hasil percobaan pertama menunjukkan bahwa perendaman biji pada etanol 96% selama 10-30 menit mampu memacu perkecambahan biji A. longifolia. Penyimpanan biji A. longifolia untuk waktu yang lama direkomendasikan menggunakan freezer dengan suhu -20 oC.A Study of Accelerated Aging and Seed Storage on the Germination of Anaphalis longifolia (Blume) Blume ex.DC. AbsractAnaphalis longifolia is a group of edelweiss flowers which has a highly conservation value. However, there are only limited information on conservation activities of A. longifolia regarded to the seed storage and cultivation. The study was conducted in the laboratory of Cibodas Botanical Garden. In this study, two experiments were carried out. In the first experiment, A. longifolia seeds were treated by ethanol 96% with 11 different immersion time (0, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 minutes). In the second experiment, seed storability and viability test were conducted after A. longifolia seeds were saved in desiccator, cabinet, refrigerator 4 oC and freezer -20 oC during 12 months. Results of the first experiment showed that soaking seeds on 96% ethanol for 10-30 minutes was able to stimulate seed germination of A. longifolia. Freezer with temperature -20 oC is recommended to storage A. longifolia for long periods.
