Abstract

The decrease of soybean productivity was caused by low quality of seed. To improve the quality of seed, soybean seed were coated  with Trichoderma sp. and adding bokashi organic fertilizer. This research aimed at finding the best dose combination of Trichoderma sp.  and bokashi fertilizer to improve the quality of soybeans. The research was conducted in the experiment field and Laboratory of Seed Technology at Padjadjaran University in April - August 2017. The experimental design in this research was Randomized Block Design (RBD). The treatments were the combination  of four dose values of coating the seed by Trichoderma sp. (0g/100 seeds, 1g/100 seeds, 2g/100 seeds, and 3g/100 seeds) and three dose  of bokashi (0g/polybag, 300g/polybag, and 600g/polybag) and each treatment was replicated three times. The experiment result showed that all treatments on soybean seeds did not affect the germination percentange, vigor index, and conductivity value, but affected the seed quantityof 600g/polybag of bokashi and without seed coating with Trichoderma sp.  on 100 seed mass and seed weight per plant.

Abstract

Selama masa penyimpanan, benih kakao mengalami berbagai proses yang akan berpengaruh terhadap kandungan cadangan makanannya dan akan berdampak terhadap kapasitas perkecambahan dan vigor benih. Penelitian ini bertujuan untuk mengetahui perubahan biokimia dan vigor benih kakao setelah disimpan maksimum 4 minggu dengan selang waktu 1 minggu. Percobaan dilakukan di Laboratorium Terpadu dan rumah kaca Balittri, Sukabumi, Jawa Barat, mulai bulan Oktober sampai Desember 2019. Rancangan penelitian yang digunakan adalah acak lengkap dengan lima taraf perlakuan lamanya waktu penyimpanan benih yang diulang lima kali. Kelima perlakuan tersebut yaitu:(a) benih tanpa disimpan,(b) benih disimpan 1 minggu, (c) benih disimpan 2 minggu, (d) benih disimpan 3 minggu, dan (e) benih disimpan 4 minggu. Parameter yang diamati selama penyimpanan adalah perubahan biokimia benih dan banyaknya benih yang berkecambah, sedangkan selama perkecambahan adalah indikator vigor benih. Hasil penelitian menunjukkan bahwa penyimpanan benih kakao selama 1-4 minggu menyebabkan penurunan kandungan lemak benih, sedangkan asam lemak bebas, protein, dan persentase benih berkecambah meningkat. Sampai umur 21 hari setelah semai, penyimpanan benih meningkatkan daya hantar listrik, tetapi menurunkan kecepatan tumbuh, potensi tumbuh maksimum, viabilitas, dan panjang hipokotil. Benih yang disimpan selama satu minggu masih memiliki vigor yang baik (viabilitas 80%), sedangkan benih yang disimpan selama 2-4 minggu menurun tingkat vigornya (viabilitas maksimum sekitar 54,4%).

Abstract

Low temperature and gibberellin treatments affected on breaking dormancy. The effects of low temperature in storage duration and gibberellin treatrments on breaking of dormancy of garlic were examined in this study. The aims of this study to determinate the best treatments for breaking garlic bulb dormancy. The sorted garlic bulbs were stored at 4 ± 0.4 ° C for 0 (control), 15, 30 and 45 days. The bulbs that have been treated by low temperature then treated by gibberellins at various concentrations including 0, 75, 150, and 225 mgL-1 by soaking for 24 hours. The bulbs were  planted in the seedling house. The low temperature storage (4±0,4ᵒC) for 45 days is more effective than 0, 15 and 30 days, while the concentration of gibberellins were not have a significant effect on breaking dormancy.  GA3 endogenous was increased during low temperature storage, on the other hand, it accelerated on breaking dormancy . The highest percentage of sprouting  bulb produced by treatment at low temperature storage for 45 days. Growth parameters such as shoot length, shoot dry weight and leaves get the best at 45 days storage time. Low temperature storage (4±0,4ᵒC) is effective in breaking dormancy of garlic bulb.
