Studies regarding the influence of the planting times in the growth and development of Allium ‘Purple Rain'

Abstract

The study presents some results regarding the influence of different bulbs planting times of the Allium ‘Purple Rain’ ornamental onion cultivar. The bulbs were planted in three different times: August 2015 (V1), October 2015 (V2) and March 2016 (V3). The plants were studied during the 2016 season. They were evaluated regarding the morpho-decorative characters, like leaves length, flowering stem height, inflorescence diameter and regarding the phenological aspects, like emergence time and flowering period. The aim of this study was to identify the planting time which favors the growth and development suitable for the studied cultivar. Compared with the experiment average, the results from every variant registred statisticaly ensured differences, for the most of the analysed characters. The most favorable planting times were the autumn and the end of the summer (V2 and V1). The spring planting time (V3) is less recommended, regarding the decrease of the plants ornamental effect and the flowering delay.
