Water stress is an important abiotic stress that limits plant growth and productivity. A pot experiment was conducted by using randomized complete block design (RCBD) with three replications (each replication containing four plants) to evaluate morphological (vegetative growth and flowering parameter) and proline content attributes that can be used...

This study was carried out in the lath house of the Horticulture Department Nursery, College of Agriculture Engineering Sciences, Duhok University. Kurdistan region, Iraq, for the period from 5th 2024 to study the effect of different levels of Zn (0, 0.50 and 0.75) and different concentration of BA (0. 50, and 100) mgl-1 on some flowering and vase...

Narcissus tazetta L, preservative solution, Paclobutrazol and CuSo4. The vase life of cut Narcissus flowers is generally short due to bent neck and wilting. This study was conducted to determine the effects of different concentrations of PBZ (0, 30, and 60) mgL-1 and CuSo4 (0, 150, 250) % on the vase life and their interaction on relative fresh wei...

This study was conducted to investigate the effects of different types of light and some factors on some vegetative growth and flowering of two cultivars of carnation plant (Dianthus caryophyllus L.). The results showed the maximum leaves number, leaf area per plant, internodes number and intermodal length were recorded under 14h incandescent (41.0...

This study was carried out in the greenhouse of the Horticulture Department Nursery, College of Agriculture Engineering Sciences, Duhok University, Kurdistan region, Iraq, for the period from 1st Aug 2020 to 1st Mar 2021, to study the effect of five supplemental light (control, natural light, Incandescent 14, Incandescent 18, mixed 14, mixed 18) ho...

This expereament was carried out in plant tissue culture laboratory of the Horticulture Department, Faculty of Agriculture, University of Duhok, Iraq, during 2014, using two types of explants (Shoot tips and nod segments) in the establishment stage. The highest percentage of shoot/explant (100%) was obtained from Stockton Morello rootstock on both...

A very high rate of multiple shoots was obtained from nodal explants of Photinia x fraseri on MS medium supplemented with a various concentration of Kin alone (1, 2, and 3) mgl-1alone and combination of Kin at (1, 2, and 3) mgl-1 with IBA or IAA at (0.2 and 0.4) mgl-1. The results show that the number of shoots/ explant was significantly affected t...

Tissue culture technique was conducted to initiate and multiplication explant of Chrysanthemum hortorum L. plant. Rooting the shoots multiplicate plants and transferred to greenhouse after acclimation. During establishment stage, several node segment explant were cultured on initiation free-hormone MS medium. A single explant was successfully initi...
