Abstract

Natural plants are highly resistant to adverse weather conditions, drought, and lack of water due to their characteristics. They have a high rate of adaptability to different conditions. Acting on the notion of climate change and limited water resources, issues such as using some of the Mediterranean plants and cultivating them as landscape plants so that they could be used for different purposes should be given more importance. The first studies on plants that are subject to trade as landscape plants include; defining the characteristics of the plant and collecting data regarding its vegetative development and production activities. The purpose of this study; determine the effects of different sowing times and treatments on the seed germination and emergence of one of the natural species of the Mediterranean flora, the Chamaecytisus hirsutus, for them to be practically seed propagated under producer conditions. To determine the effects of sowing times on germination, sowing has been conducted in October, November, February, and March. To increase germination rates, 14 different treatments have been implemented: immersion in water, stratification, scarification of the seed coat through hot water and sulphuric acid, cold (4oC) storage, two different doses of the GA3 treatment as well as a combination of these methods. From the treatments applied, the best results were obtained from; 10 section soak in boiling water, 10 section soak in boiling water + 24 hours soak in 250 ppm GA3 solution, and 10 section soak in boiling water + 24 hours soak in 500 ppm GA3 solution in November.
