Abstract

In this complete random block study we aimed to assess the morphologic reactions of Petunia under water deficiency. We used four irrigation treatments (irrigation amount of 25%, 50%, 75%, and 100% of the field's irrigation capacity. The study consisted of 8 repetitions during 6 months in the greenhouse. Data were analyzed using SPSS software, version 12.0 and the mean data were compared with each other using the least standard deviation (LSD) at a 5% level. The results showed that the root's length, weight, and dry weight, the wet to dry weight ration of the branch, number of branches, number of flowers, relative water content of the leaf, and chlorophyll content reduced. However, the flower period, profil content, and the potassium and sodium percentage increased. The Petunia can sustain low irrigation and can be used as a resistant plant to poor water conditions in green spaces.
