This study was conducted to determine the effects of different seed sowing methods on emergence rate, densities of seedling emergence and seedling growth of five Rhododendron species (R. ponticum L., R. luteum Sweet, R. caucasicum Pallas, R. simirnowii Trautv and R. ungernii Trautv). Four different sowing methods were tested, manual sowing in a row (control), mixing with plant agar, mixing with Murashige and Skoog Basal medium (MS) and mixing with stream sand. The highest seed emergence rates were obtained by manual sowing in a row (control) with R. ponticum species (76 %) followed by R. luteum (66.6 %), R. smirnowii (55.33 %), R. ungernii (24 %) and R. caucasicum (15.33 %), respectively. Similarly, the values closest to ideal seed distribution for homogenous seedling density were obtained by hand-sowing in row method. The highest seedling height was obtained in MS medium with R. ponticum (2.11 cm), followed by R. luteum (3.08 cm), R. smirnowii (4.07 cm), and R. ungernii (1.39 cm), while the effect of the seeding method on seedling growth of R. caucasicum species was not significant. To conclude, the best homogeneous distribution of seedling emergence densities of Rhododendron species was obtained by a controlled manual seeding method. However, the seed sowing with MS mixing increased significantly seedling growth in all Rhododendron species.Farklı tohum ekim yöntemlerinin orman gülü (Rhododendron ssp.) tohumlarının çıkışları ve fide gelişimi üzerine etkileri Keywords: Rhododendron Seed Sowing medium MS Agar Sand ÖZET Bu araştırma, orman gülü türlerinin (Rhododednron ponticum L., R. luteum Sweet, R. caucasicum Pallas, R. simirnovii Trautv ve R. ungernii Trautv) tohumlarınına uygulanan farklı tohum ekim yöntemlerinin çıkış süresi, fide çıkış sıklıkları ve bitki büyümesine olan etkilerini belirlemek amacıyla yürütülmüştür. Ekim yöntemi olarak, elle sıraya ekme (kontrol), plant agar ile karıştırma, MS ile karıştırma ve dere kumu ile karıştırma olmak üzere dört farklı tohum ekim yöntemi denenmiştir.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
