THE EFFECT OF SOME TREATMENTS ON THE FLOWER GROWTH CHARACTERISTICS OF TWO PLANT VARIETIES OF TULIPA. SSP

Abstract

This study was conducted within the wooden canopy of the Department of Horticulture and Landscape Engineering / College of Agriculture and Forestry / University of Mosul, during the period from November 1, 2023 to June 1, 2024, with the aim of studying the effect of soaking bulbs with gibberllic acid (GA3) at different concentrations (0, 100). 200 mg L-1 and spraying with organic fertilizer (Organic Extra plus) at different concentrations (0, 2, 4) ml L-1 and the interaction between the characteristics of vegetative and flowering growth and the yield of bulbs and follicles for two types of Tulip bulbs. Spp ( Tulipa. Spp (.The study was carried out using a factorial experiment in a randomized complete block design (R.C.B.D.) in a split plot, with three replicates and 10 plants per- replicate. The results indicated that the Violet Negrita variety was earlier in the time required for the flower to open fully, as the flowers formed after 131,174 days. It also excelled in the length of the flower stand, 33.083 cm. The fresh weight of the flower stand and flower was 11.498 grams. The diameter of the flower stand was 0.827 cm. The duration of the flowers remaining on the plant was 5.583 days. Flower diameter. cm m Flower age 6,037 days.
