Pengaruh Ketinggian Tempat Terhadap Pembungaan, Produksi, dan Mutu Benih Botani Bawang Merah

Abstract: <p>Kendala produksi benih bawang merah (Allium cepa var. ascalonicum) asal biji atau TSS di dataran rendah adalah rendahnya persentase pembungaan dan pembentukan biji (seed-set.).Untuk meningkatkan pembentukan biji, bawang merah memerlukan suhu 17–19oC. Di Indonesia, suhu udara tersebut hanya terdapat di dataran tinggi&gt;1.000 m dpl.. Percobaan dilaksanakan di Kebun Percobaan Balai Penelitian Tanaman Sayuran (Balitsa) Lembang (1.250 m dpl.) dan di Kebun Percobaan Paseh Subang (100 m dpl.) yang sekal… Show more

“…The scarcity of seeds is due to the nature of seasonal onion production and short shelf life. According to Hilman et al (2014) scarcity of seeds occurs because farmers tend to sell seeds that have been set aside for the next planting season when the price of shallots on the market tends to rise. Therefore, to overcome the scarcity of tuber seeds, quality onion seeds have been developed, namely botanical seeds or true shallot seeds (TSS).…”

“…Shopa et al (2014) stated that TSS production in the Bali Karet cultivar with a 16-hour photoperiod increased TSS seed production from 0.48 g / plant to 1.30 g / plant while administering 200 ppm GA3 was able to increase TSS production from 0.53 g / plant to 0.70 g / plant. Hilman et al (2014) stated that TSS production in the highlands is higher (2.58 g / plant) than in the lowlands (0.35 g / plant) but the quality of TSS in the lowlands is better than in the highlands.…”

“…Di daerah tropis yang bersuhu tinggi masalah pembungaan dan pembentukan biji bawang merah menjadi kendala utama dalam produksi benih TSS. Namun hasil penelitian sebelumnya yang dilakukan oleh Satjadipura (1990), Khokhar (2009), Rosliani et al (2012), Hilman et al (2014), menunjukkan bahwa teknik induksi pembungaan melalui vernalisasi, aplikasi benzilaminopurin (BAP), dan boron dengan penanaman di dataran tinggi yang bersuhu rendah (<18 o C) dapat meningkatkan pembungaan dan pembentukan biji TSS.…”

“…Di dataran rendah (0-300 m dpl. ), terbuka peluang untuk peningkatan pembungaan dan produksi TSS (Hilman et al 2014). Tingkat pembungaan dan produksi biji di dataran rendah lebih rendah daripada di dataran tinggi, tetapi ada indikasi kapsul (istilah buah untuk genus Allium) dan biji yang dihasilkan lebih bernas daripada yang dihasilkan di dataran tinggi (Hilman et al 2014).…”
