Abstract

Nyawai (Ficus variegata Blume) merupakan salah satu jenis pohon yang memiliki prospek yang baik untuk hutan tanaman. Informasi tentang aspek biologi reproduksinya masih terbatas. Penelitian ini bertujuan untuk mengetahui karakteristik morfologi bunga dan buah nyawai, serta tahapan perkembangan fig. Penelitian dilakukan di Kebun Raya Cibodas, Jawa Barat. Kegiatan penelitian meliputi: 1) pengamatan morfologi bunga dan buah, dan 2) pengamatan perkembangan fig. Hasil penelitian menunjukkan bahwa karakteristik morfologi fig nyawai yang dijumpai di Kebun Raya Cibodas, memiliki variasi yang tinggi dalam hal ukuran dan warna. Berdasarkan karakteristik morfologi bunga, secara individual ditemui dua tipe pohon yang mencirikan sebagai pohon menghasilkan bunga jantan dan penghasil bunga betina. Perbedaan antara tahap bunga, buah muda, dan buah matang tidak dapat dibakukan berdasarkan karakteristik morfologi eksternal dari fig. Tingkat kematangan buah nyawai dapat dilakukan dengan membelah fig. Nyawai tahap kuncup bunga berakhir sekitar 6-11 hari setelah munculya tunas fig, dan tahap bunga berakhir 11-26 hari. Perkembangan kuncup bunga menjadi buah yang matang memakan waktu sekitar 2-3 bulan. Hasil penelitian menyarankan untuk tidak mengumpulkan benih dari fig yang berukuran kecil, meskipun mereka memiliki karakteristik fisik fig yang matang.

Abstract

Benih kayu kuku yang mengalami kemunduran mutu benih masih dapat ditingkatkan vigor nya melalui pemberian hormone priming (gibberellic acid/GA3). Penelitian ini bertujuan untuk mengetahui konsentrasi hormone priming dan lama perendaman yang efektif untuk meningkatkan vigor dan konsentrasi uji cepat tetrazolium untuk menentukan viabilitas benih kayu kuku. Penelitian ini menggunakan rancangan acak lengkap (RAL) 2 faktor. Faktor pertama konsentrasi hormon GA3 yaitu 100 ppm, 300 ppm, dan 500 ppm. Faktor kedua lama perendaman yaitu 24 dan 48 jam. Hasil penelitian menunjukan perendaman benih konsentrasi GA3 300 ppm merupakan hormone priming yang efektif dalam meningkatkan daya hantar listrik, nilai perkecambahan, dan rata-rata waktu berkecambah. Pengujian tetrazolium menunjukkan bahwa benih kayu kuku viabel atau masih hidup yaitu benih berwarna merah karena terdapat endapan trifenil formazan.

Abstract

Suboptimal environmental conditions cause low imbibition rate in maize plants, thus disrupting enzyme activation and food availability for the sprouts, and inhibiting the germination process. This study aims to provide a better understanding of the imbibition pattern and physiological characteristics of germination, hopefully obtaining useful information in the development of seed processing techniques and more efficient agricultural technology. The maize seeds used in this study were the seeds of four maize varieties. The imbibition pattern was obtained by weighing the seeds from 0 to 120 hours with a 6-hour time interval. The results showed that the four varieties showed a typical three-phase imbibition pattern with almost the same time. Overall, the highest seed growth and germination was found in Jantan F1 and Paramita, which have great potential for use in seed propagation, while Baruna variety showed low seed quality and needs further evaluation for improvement.

Abstract

One of the problems with acidic soil is its high aluminum (Al) content, which can cause toxicity to plants. this study was conducted to evaluate the preliminary growth and tolerance of L. leucocephala seedlings to Al exposure. This study used a completely randomized design (CRD) with one factor, namely Al concentration, consisting of 5 levels (0, 2, 4, 6, and 8 mM). The evaluation of seedling growth and tolerance assessed included: height, root length, dry weight of roots and shoots, tolerance index, SPAD (Soil Plant Analysis Development) chlorophyll, and photosynthesis rate. The results showed that Al exposure reduced all growth parameters (height, root length, dry weight of roots and shoots) of L. leucocephala seedlings. The tolerance index of L. leucocephala seedlings also decreased significantly (up to 43.68%) with increasing Al concentration. Meanwhile, chlorophyll and photosynthesis rate parameters increased with Al exposure of 2-4 mM, but decreased with higher Al exposure (6-8 mM). The threshold value or sensitivity of L. leucocephala seedlings to Al exposure was less than two mM. The L. leucocephala species can also serve as an alternative for land rehabilitation with high Al content as post-coal mining land.
