Abstract
Tuberose is one of the most important cut flowers in Iran and the world. In this experiment, effect of microelements Fe, Zn, Cu and Mn on inflorescence length, inflorescence bunch length, number and diameter of floret, diameter of inflorescence bunch and vase life of tuberose flowers were studied. This study was based on four separate completely randomized experimental design with four replicate and four concentrations include: 0, 2, 4 and 6 mg/lit for each microelement. The fertilizers were sprayed in three stages. The first stage was at eight leaf stage (after 30 days). The second stage was, one month later from first stage and the third stage was one month after second stage of plant growth. The results showed that the concentrations of 6 mg/lit of Fe SO4 on inflorescence length and floret number, 2 mg/lit on bunch length and 4 mg/lit on floret opening was significant (P≥1%). The concentrations of 2 mg/lit of Cu SO4 on length of flower bunch and floret number, 6 mg/lit on floret opening percentage and inflorescence diameter and 4 mg/lit on length of inflorescence was effective. Almost all traits were affected by Mn SO4 with 6 mg/lit concentration and vase life reached to 12.4 days.
