Duman Solüsyonlarına Maruz Kalan Bazı Çim Türlerinin Çimlenme ve Fide Büyümesi

Abstract

This study aimed to investigate the effect of priming with plantderived smoke solutions (SS) on the germination, seedling growth and chemical content of three turfgrass species (Lolium perenne, Festuca arundinacea, Poa pratensis). SS was applied at six concentrations (0, 0.5, 1, 5, 10 and 20%) in petri and pot conditions. In petri condition, SS did not stimulate the germination speed, and the highest concentrations (20%) led to lower values than control. In the pot conditions, seedling growth and chemical content were significantly stimulated by the SS. The effect of the SS varied depending on the species and concentrations. Shoot and root length in grass species were improved by the SS, except in P. pratensis for shoot length. Compared to control, higher shoot dry weight in F. arundinacea (1%) and higher root dry weight in L. perenne (5%) and F. arundinacea (0.5%) were determined at certain concentrations. These results showed that priming with SS at appropriate concentrations may lead to healthy and vigorous seedlings. When seedling vigor and visuality are evaluated together, it has been determined that priming with low concentrations of SS such as 0.5 and 1% can produce vigorous seedling.
