Growth Assessment of the Potted Cultivation of <i>Veronica rotunda</i> var. <i>subintegra</i> (Nakai) T.Yamaz.

Abstract

This study aimed to establish effective pot cultivation methods for Veronica rotunda var. subintegra (Nakai) T.Yamaz. that has high ornamental value. Seedlings of uniform size were transplanted into plastic pots and treated with different shading ratios, coated fertilizer, additional fertilizer, dwarfing agents, and pinching. Our results show that all shading treatments decreased the growth of V. rotunda seedlings, with higher shading ratios having a m ore significant inhibition i mpact on g row th. Coated fertilizer significantly increased plant height, internode length, stem diameter, and number of leaves; however, the application of additional fertilizer had no significant effect on plant growth. Applying diniconazole at any concentration caused dwarfing in the study plants, but internode seedling length was inhibited more significantly as diniconazole concentration increased. The application of daminozide 1000 mg·L-1 had no significant effect on growth; however, at 2000 mg·L-1, it caused dwarfing. Furthermore, the pinching treatment had no conclusive effect on plant growth.
