| Abstract | Petunia seeds are of high-value but their sizes are small and their germination rates are not uniform which have made them difficult to handle. The objective of this research was to enhance petunia seed quality and seedling growth through pelleting. This experiment was conducted during September 2019-September 2021. Treatments consisted of control seeds, seeds pelleted with pumice (P) and KCl 0, 0.5, 1.0 and 2.0 g/H2 O 10 ml using hydroxypropyl methylcellulose(HPMC)4 %W asabinder, with CRD 4reps. Results showedthatgermination rates of control and seeds pelleted with P + KCl 2.0 g/H2 O 10 ml after storage 0-12 months werenot statisticallydifferentat62.5-78.0 % respectively. While, AA-test revealedthat control and seeds pelleted with P + KCl 2.0 and 1.0 g/H2 O 10 ml germinated at the rates of 72.5, 71.1 and 68.0 %, respectively. Moreover, the speed of germination of seeds pelleted with P + KCl 2.0 g/H2 O 10 ml after storage 12 months were not different with control seed, 4.1 and 4.0 plants/day. Whereas, the seedling growth of seed pelleting with P + KCl 2.0 g/H2 O 10 were higher than control seed at 3-12 months after storage. Thus, petunia seed pelleting with P+ KCl 2.0 g/H2 O 10 ml was not only increased seed size to manage easier, but also keep stability of the germination and improved seedling growth. Thus, such pelleting method enhances petunia seed quality and promote commercial production. |
