Effect of Transplanting Date and Pot Shapes on Vegetative Growth and Flowering of Antirrhinum Majus L. Plants

Abstract

A factorial experiment using a randomized complete block design (RCBD) was conducted in a local nursery in the city of Duhok in northern Iraq from January 10, 2021, to January 6, 2022, to show the impact of planting date and pot shape on Flowering and Seed Production of Snapdragon plants under various production systems. In the experiment, which comprised 24 experimental units and four replications, there were 92 pots altogether, making up eight pots each experimental unit. The second group of Snapdragon’s Snapshot Mix cultivar was used in the experiment (Antirrhinum majus L.). Two variables in the experiment were the time since germination and the design of the pots. The vegetative and flowering growth characteristics that were studied: plant height, number of leaves, leaf area, inflorescence length, inflorescence diameter, flowering time, number of inflorescences, total number of florets and marketing acceptance score. The results showed that the delayed transplanting date two weeks after germination was significantly better in terms of the studied traits, which were the number of leaves (62.30 leaves plant-1), leaf area (86.85 cm2), inflorescence length (10.49 mm), flowering time (27.07 days), number of inflorescences (10.33 inflorescence plant-1), the total number of florets was (51.59 florets plant-1). From the results, it is clear that the round pot’s shape was clearly superior at the conclusion of the experiment.
