“…Kata kunci: after-ripening, kacang bogor, kulit keras, permeabilitas, rasio GA/ABA PENDAHULUAN Kacang bambara (kacang bogor) merupakan underutilized crops yang dimanfaatkan baik sebagai tanaman hortikultura maupun sumber pangan pokok alternatif. Kandungan gizi kacang bambara meliputi karbohidrat 68.0%, protein 17.7%, lemak 6.6%, serat 3.5%, abu 4.2% (Abu-Salem dan Abou-Arab 2011), juga mengandung kalsium, besi, zink, magnesium dan mangan (Adelanwa et al, 2017), serta berpotensi sebagai tanaman tahan cekaman kekeringan (Mayes et al, 2019). Potensi hasil kacang bambara cukup baik, mencapai 11.5 ton polong segar ha -1 untuk kultivar lokal Lembang di Kalimantan Selatan (Adhi dan Wahyudi, 2018) dan 20.0-22.5 ton polong segar ha -1 untuk beberapa galur harapan (Bakti et al, 2018).…”

Bambara groundnut seeds often show unsynchronized and slow germination even though on newly harvested seeds. This might be due to the presence of seed dormancy. Therefore, the objective of this research was to obtain the information on seed dormancy and germination behaviour of bambara groundnut seeds during desiccation. The experiment was arranged in a nested design. Dormancy breaking treatments (untreated, mechanical scarification, soaking in 1% KNO3 for 2 hours, mechanical scarification followed by KNO3 soaking) were nested in each of the desiccation levels (fresh seeds with 54.7% moisture content (mc), desiccated seeds with 44.4%, 18.0%, 15.4%, and 12.1% mc). The results showed that newly harvested seeds were in dormant state. Seed desiccation did not increase the intensity of seed dormancy, even resulted in an increase in field emergence (at 30 days after planting) from 43.9% in fresh seeds to around 70% in dry seed (12-15% mc). Seed desiccation (from 44.4% mc to 12.1% mc) increased the field emergence, although it was inadequate to break the dormancy completely. Meanwhile, seed desiccation tended to increase the GA/ABA ratio, but the seed permeability was decreased. The fact showed that seed desiccation reduced the intensity of dormancy of bambara groundnut seed, therefore, it is suggested to modify the drying method in order to accelerate the increasing of GA/ABA ratio while keeping the testa permeable. Keywords: after-ripening, GA/ABA ratio, hard seed, kacang bogor, permeability

“…Indonesian people usually consume bambara beans as a horticultural product, but it is potential as an alternative staple food and functional food as well. The nutritional content of bambara beans includes carbohydrates (68.0%), protein (17.7%), fat (6.6%), fiber (3.5%), ash (4.2%) (Abu-Salem and Abou-Arab 2011), calcium, iron, zinc, magnesium, and manganese (Adelanwa et al 2017).…”

Pre-harvest sprouting on high-level seed dormancy of bambara groundnut (Vigna subterranea) landraces

Abstract. Sari M, Ilyas S, Suhartanto MR, Qadir A. 2021. Pre-harvest sprouting on high-level seed dormancy of bambara groundnut (Vigna subterranea) landraces. Biodiversitas 22: 5617-5623. Bambara groundnut (Vigna subterranea (L.) Verdc.) is an underutilized crop. Therefore, its seed quality is not guaranteed. Pre-harvest sprouting (PHS) on bambara groundnut seeds can be found either due to the unpredictable rainfall or the late harvesting and plants are still in the field when rainfall. Conversely, seed dormancy causes a problem for planting. The objective of this research was to identify seed dormancy and PHS of four bambara groundnut landraces and other related seed characters. Four landraces (Madura, Sukabumi, Brown Sumedang and Tasikmalaya) were planted at the end of May 2017. Seeds were harvested at physiological maturity (130 days after planting) during the beginning of the wet season (early October 2017). The result showed that there were variations of PHS among landraces from 1% to 12%, and variations of seed dormancy rates from 62% to 82%. There were differences in seed color, seed size, tannin content, seed hardness, and imbibition rate. However, these characters could not clearly explain the diversities in PHS and seed dormancy. There was a high genetic diversity within Tasikmalaya landrace because this landrace had the highest PHS (12%) and the highest dormancy rate (82%) as well, although both characters are contradictory. This diversity needs further research, mainly to avoid the disadvantages due to PHS.
