The effects of different planting times on cut flower yield and quality of some Gladiolus grandiflorus L. varieties grown in ecological conditions of Siirt province, Turkey

Abstract

This study was carried out, in the research and application garden of Siirt University,Faculty of Agriculture, Department of Horticulture in Turkey in 2015. The aim of the study is to observe in different planting times in different cultivars of Gladiolus in terms of yield and quality in Siirt ecological conditions. Four different Gladiolus cultivars (Nova Lux, Purple Flora, White Swan and Red Beauty) and three different planting time (8 May, 23 May and 6 June) were used in the study. Some phenological observations were made and morphological evaluations were taken in terms of yield and quality on Gladiolus varieties. May 23 has resulted to be the best time for planting Gladilous in Siirt. When look at their cut flower properties, it has been found out that White Swan and Purple Flora are the most appropriate ones in terms of plant height, spike length, stem length and thickness, stem weight and number of candles/spike.
