Abstract

Ornamental plants play a crucial role in urban landscapes due to their aesthetic and ecological value. Improving germination and early seedling development is essential for high-quality ornamental plant production. This study investigated the effects of different salicylic acid (SA) concentrations (0.00, 0.25, 0.50, 0.75, and 1.00 mM) on the germination and early seedling growth of Mirabilis jalapa L. under controlled greenhouse conditions. The results indicated that, among the tested concentrations, 0.25 mM SA increased the germination rate by 11.10% compared to the control group, and improved plant height, leaf number, and root length by 7.70%, 7.44%, and 11.49%, respectively. In contrast, higher concentrations (0.50, 0.75, and 1.00 mM) inhibited the growth parameters. Germination time was not significantly affected by SA treatments. These findings suggest that low-dose SA applications may positively influence early seedling vigor and growth performance, which can indirectly contribute to ornamental plant quality. This study provides baseline data for the potential use of SA in ornamental horticulture and highlights the need for further research on different species and environmental conditions.

Özet

Süs bitkileri, estetik ve ekolojik değerleri nedeniyle kentsel peyzajlarda önemli bir rol oynamaktadır. Çimlenmenin ve erken fide gelişiminin iyileştirilmesi, yüksek kaliteli süs bitkisi üretimi için çok önemlidir. Bu çalışma, kontrollü sera koşullarında Mirabilis jalapa L. bitkisinin çimlenmesi ve erken fide gelişimi üzerindeki farklı salisilik asit (SA) konsantrasyonlarının (0,00, 0,25, 0,50, 0,75 ve 1,00 mM) etkilerini araştırmıştır. Sonuçlar, test edilen konsantrasyon aralığında, 0,25 mM SA'nın kontrol grubuna kıyasla çimlenme oranını %11,10 artırdığını ve bitki boyu, yaprak sayısı ve kök uzunluğunu sırasıyla %7,70, %7,44 ve %11,49 oranında iyileştirdiğini göstermiştir. Buna karşılık, daha yüksek konsantrasyonlar (0,50, 0,75 ve 1,00 mM) büyüme parametrelerini engellemiştir. Çimlenme süresi SA uygulamalarından önemli ölçüde etkilenmemiştir. Bu bulgular, düşük dozda salisilik asit (SA) uygulamalarının erken dönem fide gelişimini ve büyüme performansını olumlu yönde etkileyebileceğini ve bunun da dolaylı olarak süs bitkisi kalitesine katkıda bulunabileceğini göstermektedir. Bu çalışma, süs bitkisi yetiştiriciliğinde SA'nın potansiyel kullanımı için temel veriler sağlamakta ve farklı türler ve çevresel koşullar üzerinde daha fazla araştırmaya duyulan ihtiyacı vurgulamaktadır.
