Description
Bulbil merupakan salah satu metode perbanyakan secara vegetatif untuk mendapatkan bibit porang namun membutuhkan waktu yang panjang untuk menjadi bibit berkualitas baik yang siap ditanam. Pemberian zat pengatur tumbuh dapat membantu mempercepat tumbuhnya tunas. Penelitian ini dilaksanakan untuk mengetahui efektivitas ZPT alami yang bersumber dari air kelapa dan bawang merah pada pembibitan bulbil porang. Penelitian dilakukan pada bulan April–Juni 2022, bertempat di Desa Bontotangnga, Kecamatan Bontolempangan, Kabupaten Gowa, Provinsi Sulawesi Selatan. Metode yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan empat (4) perlakuan perendaman benih dan empat (4) kali ulangan sehingga diperoleh 16 plot perlakuan. Perlakuan yang digunakan adalah kontrol (air biasa), air kelapa 250 mL/L air, ekstrak bawang merah 150 mL/L air, dan air kelapa 250 mL/L + ekstrak bawang merah 150 mL/L air. Hasil penelitian menunjukkan perlakuan dengan air kelapa 250 mL/L + ekstrak bawang merah 150 mL/L memberikan pengaruh terbaik pada pertumbuhan benih bulbil porang dengan rata-rata waktu muncul tunas 2,3 hari, tinggi tanaman 28,44 cm, diamater batang 7,18 mm, dan volume akar bibit 8,17 mL. Hal ini berarti perendaman dengan air kelapa 250 mL/L air + ekstrak bawang merah 150 mL/L air pada benih bulbil porang efektif memberikan peningkatan pada waktu munculnya tunas, tinggi, dan diameter batang, serta volume akar bibit porang.
Bulbil is one of the vegetative propagation methods to get porang seedlings, however it takes a long time to become good quality seedlings that are ready to be planted. The application of growth regulators can help accelerate the growth of shoots. This research was done to know the effectiveness of natural PGRs from coconut water and shallots extract in bulbil porang nurseries. The research was done from April to June 2022, located in Bontotangnga Village, Bontolempangan District, Gowa Regency, South Sulawesi. The method used was a Group Randomized Design with four (4) seed soaking treatments and four (4) replays so that 16 treatment plots were obtained. The treatments were control (just water), coconut water 250 mL/L of water, shallot extract 150 mL/L of water, and coconut water 250 mL/L of water + shallot extract 150 mL/L of water. The results of this research showed that the treatment with coconut water 250 mL / L + shallot extract 150 mL / L had the best influence on the growth of bulbil porang seeds with an average bud emergence time of 2,3 days, plant height of 28,44 cm, stem diameter 7,18 mm, and seedling root volume 8,17 mL. This means that soaking with coconut water 250 mL/L + shallot extract 150 mL/L water on the seeds of bulbil porang effectively provides an increase in the number of bud appearance, height, and diameter of the stem, as well as the volume of roots of porang seedlings.
