Plant Growth Regulators: An Overview

Advances in Blueberry (Vaccinium spp.) In Vitro Culture: A Review

“…Growth regulators play pivotal roles in plant tissue culture, influencing various aspects of plant growth and development (Table 3); for instance, they regulate stem elongation, controlling the length and structure of stems [79]. Additionally, growth regulators contribute to tropism, guiding the direction of plant growth in response to environmental stimuli such as light and gravity [79]. Moreover, they are involved in maintaining apical dominance, where the terminal bud at the top of the plant inhibits the growth of lateral buds [79].…”

Besides these functions, growth regulators also regulate processes such as cell division, differentiation, and organogenesis, ensuring the successful propagation and manipulation of plants in tissue culture systems [79].…”

Upaya Mempercepat Kematangan Buah Kopi Arabika dengan Aplikasi Hormon

“…Hormon tanaman seperti auksin, sitokinin, etilen, giberelin, dan asam abisat diproduksi di satu bagian tanaman dan diangkut ke bagian lain untuk memicu respons fisiologis pada sel atau organ target. Etilen merupakan satu-satunya hormon berbentuk gas, memiliki peran krusial dalam proses pematangan buah (Bhatla & Lal, 2023;Hano, 2022). Penelitian García Parrales et al ( 2023) menunjukkan aplikasi etilen mempercepat pematangan tomat, mengurangi waktu alami dari 20 hari menjadi 4 hari.…”

“…Dalam kopi, NAA membantu dalam peningkatan jumlah bunga dan buah, secara efektif meningkatkan hasil per pohon. Penggunaannya harus dikendalikan untuk menghindari efek samping seperti pertumbuhan yang tidak diinginkan atau dominansi apical (Bhatla & Lal, 2023;Bons & Kaur, 2020;Katel et al, 2022;Rajbhar et al, 2023). Sementara itu Gibberelin, merupakan hormon yang vital dalam mengatur pertumbuhan dan perkembangan tanaman.…”
