Abstract

The purpose of this study was to determine the effects that different container conditions have on Pinus densiflora seedling growth. Under greenhouse cultivation, there were no statistical differences observed in plant height and the number of branches; however, significant differences in root collar diameter and root status were observed. In control container growth conditions, the roots grew in an abnormal spiral shape, while in negative phototropism container growth conditions the roots grew in a vertical shape. In outdoor cultivation, seedlings in various container growth conditions showed significant differences. The seedlings that were grown in negative phototropism container growth conditions showed the greatest increases in height, number of branches, root collar diameter, and root growth. This study determined that seedling roots in negative phototropism container growth conditions grew vertically, thus displaying successful rooting when they were transplanted outdoors. This resulted in favorable measurements in height, number of branches, root collar diameter, and root growth.

Highlights

With increasing interest in the environment, the trend of using plants for landscaping is moving away from an emphasis on the quantity of limited tree species toward high quality, standardized plant production [1]
When they were measured on 12 September 2017, container growth conditions (CGCs)-1, container growth condition 2 (CGC-2), and container growth condition 3 (CGC-3) showed higher moisture contents than container growth condition 4 (CGC-4), container growth condition 5 (CGC-5), and container growth condition 6 (CGC-6), with the differences being statistically significant (Table 3)
The results showed that the negative phototropism CGCs (CGC-4, CGC-5, and CGC-6)

Summary

Introduction

With increasing interest in the environment, the trend of using plants for landscaping is moving away from an emphasis on the quantity of limited tree species toward high quality, standardized plant production [1]. The systematic production of healthy, good quality, standardized plants for landscaping is a crucial process used to increase initial plant rooting promoting growth; container production methods are often used to achieve this [2]. Technologies and research regarding container growth conditions are crucial because containers have a direct influence on the root shape formed in the container during the nursery period, and have significant effects on short-term and long-term growth, even after planting [6,7]
