Özet:

This study aimed at determining the effects of two different levels of water stress (white and brown flowers) varieties on plant water consumption (ET), the physiological characteristics (plant temperature, stoma conductivity, chlorophyll index, leaf proportional water content), the morphological characteristics (plant length, plant diameter, flower number, petal number, petal length, petal thin and flower diameter) and the harvest characteristics (root length, root dry weight, plant age weight, plant dry weight). The study was conducted in 2019 at Çanakkale Eighteen March University, Ziraat Faculty, Plant Stress Monitoring and Thermography Laboratory (BISITLAB). During the test, the temperature was kept at 20°C for 16/8 hours of photoperiot application. In the test, four different watering subjects were created (7 days of completion of the available water retention capacity of humidity reduced to 100% (control), 75% and 50% and 25%). Fysiological and morphological measurements have been made on all plants before each irrigation. The study found that the total ET values obtained during the test period in the varieties of brown and white flowers were 83-117 mm and 78-116 mm respectively. The effect of water stress on the physiological characteristics measured within the test has been shown to be greater in both varieties than in morphological and harvest end measurements. Furthermore, when compared varieties on the same water stress issues, morphological measurements showed that the number of flowers and flowers in the coloured flower flower plant are greater than the white flower flower. As a result, it can be said that in water stressed conditions, both varieties of shells show similar reactions.
