“…This chemical compound reduces the plant cell size, shortens the length of the stem, and inhibits the growth of the apical meristem [36]. Paclobutrazol is another effective and widely used growth retardant, which shortens the length of stems but can also reduce the size of bracts in the case of excessive use in ornamental plants [37]. The effect of this retardant can be described by a compact growth plant, which also accelerates the inflorescence and reduces the height of the potted ornamental plants [38].…”

In Eastern Europe, the traditional marketing of cyclamen is in the period from the middle of February to the middle of March. The poor light of winter months and the higher number of plants (because of the reduction in heating costs) often result in elongated plants. To avoid this, it is recommended to use plant growth retardants. At the same time, another problem is that flowers do not rise from the level of rosette due to the unfavorable cultivation conditions. This can be solved with growth stimulants. In the experiment, we tested the effect of growth regulators on the growth of a frequently used variety of cyclamen. We used daminozide and paclobutrazol plant growth retardants for height control and gibberellic acid (GA) and benzyladenine (BAP) as growth promoters for increasing the number of flowers and the length of stems. The results show that daminozide and paclobutrazol are both effective for height control in cyclamen production.

“…Aplikasi Ethrel dapat menyinkronkan dan mempercepat pematangan buah, sehingga memudahkan panen serempak dan mengurangi biaya. Hal ini penting untuk meningkatkan efisiensi panen yang selanjutnya secara tidak langsung berperan besar dalam ekonomi produksi (Nishijima, 2023;Rajbhar et al, 2023). Sementara itu, NAA (Naphthaleneacetic Acid) adalah jenis auxin sintetik yang digunakan untuk merangsang pertumbuhan akar dan buah.…”

“…Pada tanaman kopi, giberelin digunakan untuk meningkatkan ukuran buah dan memperbaiki kualitas biji, selain itu juga berperan dalam memecah dormansi biji dan memicu perkecambahan. Gibberelin sering digunakan dalam kombinasi dengan PGR lain untuk maksimalisasi efek sinergis, menciptakan kondisi ideal untuk pertumbuhan dan pematangan buah (Bhatla & Lal, 2023;Castro-Camba et al, 2022;Katel et al, 2022;Nishijima, 2023).…”

Coffee is a plantation crop with significant economic value, commonly processed into flavorful beverages. Arabica coffee farmers generally face challenges during harvest and post-harvest, particularly with the necessity to pick ripe, red berries. However, during harvest, farmers often do not selectively pick the cherries, resulting in the collection of not only red but also yellowish or green berries. Plant growth regulators (PGRs) are synthetic chemicals that mimic the role of endogenous hormones. This study aims to investigate the interaction between different hormone types and varieties on the ripening of Arabica coffee berries, assess the impact of various hormones on berry maturity, and evaluate the effect of different varieties on the ripening process. The research utilized a completely randomized design (CRD) with two factors: plant growth regulators (PGRs) and coffee varieties. The observed parameters included the number of fruiting nodes per tree, the number of fruits per node, the number of red fruits in the first harvest, the number of red fruits in each subsequent harvest (across three stages), and the weight of green beans per 100 seeds. The analysis revealed no significant interaction between the application of different types of growth regulators (PGRs) and coffee varieties in accelerating the maturation of Arabica coffee berries. Notably, the Yellow Catura variety treated with the growth regulator Ethrel showed a better effect in accelerating berry maturity.
