Research ArticleOpen accessIn the abstractIn vitro Polyploid Induction in Phalaenopsis Aphrodite by PendimethalinPrasetyorini Djarot, Deden Sukmadjaja, Fadya Annisa Chaesarani, SukonoPhalaenopsis aphrodite is a type of orchid with high ornamental and economic value. However, its development for commercial needs in Indonesia is still hindered by the limited availability of varieties. Therefore, enhancing genetic diversity is necessary, one of which is through polyploid induction. Several previous studies reported that pendimethalin effectively duplicates the chromosome numbers of various plant species. The aim … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 22 Aug 2026 · 854 accessesView PDFCite
