Effect of bioregulators treatments on Allium Saxatile M. Bieb.

Abstract

This research was conducted to investigate the influence of the bioregulators on the Allium saxatile M.Bieb. vegetative growth and flowering period. There were used two bioregulators, represented by a growth retardant, Cycocel (CCC) and a growth stimulant, Gibberellic Acid (GA3), applied by foliar sprayng, in three concentrations (250, 500 and 1000 ppm). The plants were evaluated with reference to the vegetative growth, like leaves length, leaves number, flowering stem height, inflorescence diameter and with reference to the flowering period. The analysed results, highlighted that aplication of GA3 promote the vegetatives growth. The treatments with CCC had a noticeable influence in the flowering period delay. Therefore, treated with CCC, the plants bloomed ealier with about 10-20 days than the other variants.
