“…of Cha et al (2017) reporting that there was no significant difference in surface area even if the irrigation volume increased as long as the frequency of irrigation was less than three times during pine seedlings. At root level, both systems showed decreases when the irrigation amount was excessive, similar to results of Cha et al (2017) reporting that the dry weight in the rhizosphere increased as the amount of irrigation during pine seedlings increased. However, it decreased slightly when the amount of irrigation exceeded a certain level probably due to the lack of breathability caused by excessive moisture in the soil rhizosphere (Choi et al, 1997).…”

The objective of this study was to examine responses of vegetable seedlings grown on plug seedling system (Plug) or cylindrical paper pot (CPP) system to water stress. Cucumber 'Jo-eun' was grafted onto stock 'Huckjong'. Watermelon 'Jo-eunggul' was grafted onto stock 'Bulojangsaeng'. Growth factors of seedlings were investigated. Top-to-root ratio (TRR), compactness (CP), and Dickson Quality Index (DQI) as indicators of seedling quality were calculated based on time periods. Results revealed that the overall shoot of cucumber and watermelon grown in the CPP system was higher than the shoot grown in the Plug system. In both CPP and Plug systems, the total growth decreased as the irrigation water volume increased, while the seedling stem was thick and hard. The higher the irrigation water level, the greater was the inhibition of root zone development. When the degree of growth reduction was comparing between the two systems, the growth rate of cucumber was lower in the CPP system than that in the Plug system, whereas the growth rate of watermelon was decreased due to increased irrigation water content only in the Plug system. The degree of growth tended to decrease with increasing volume of irrigation water in both CPP and Plug systems. The degree of decreased growth was greater in the Plug system than in the CPP system. The decrease started to occur in the mid-growth phase. It intensified with further growth. In conclusion, extensive irrigation during early stages of growth can enhance the growth of seedlings in both CPP and plug systems. However, growth was suppressed after reaching a certain level. This effect was relatively lower in the CPP system than in the Plug system.

“…As a result of examining RCD, rootstock growth and dry matter production of container seedlings of pine trees irrigated at intervals of 1, 2, 3, 5, 7, 10, and 15 days, the best growth response was found to be highest at intervals of 1 day of irrigation [29]. Additionally, the shorter the irrigation cycle, the better the growth of container seedlings of pine trees, but the total root length was higher at 3 days than at 2 days or 1 day.…”

“…In this study, the QI of Q. myrsinifolia seedlings was 0.124-0.257 in the irrigation cycle test and 0.149-0.262 in potting soil. Cha et al [29] reported that the QI values of pine seedlings were 0.071, 0.067, and 0.065 when irrigated at intervals of 1, 2, and 3 days, respectively.…”

The importance of evergreen oak species is increasing due to changes in the ecosystem caused by climate change and environmental changes such as fine dust and carbon dioxide. The Quercus myrsinifolia Blume seeds showed a recalcitrant seed property, where the germination rate decreased when the moisture content was decreased. For seedling propagation of evergreen oak, the effect of oak seed coat (pericarp and testa) removal on germination and seedling growth as well as the effect of potting soil and irrigation cycle on seedling quality were investigated. The germination rate and germination characteristics of Q. myrsinifolia evergreen oak seeds showed significant differences depending on the storage period and the presence or absence of seed coat. Seed coat removal significantly increased germination rate compared to intact seeds, accelerated mean germination time, and increased germination rate and germination value. There was no significant difference in germination rate according to the storage period. The growth of Q. myrsinifolia seedlings was much better in the seeds with the seed coat removed than the intact seeds. The root collar diameter of seedlings germinated from intact seeds was 2.44 mm, and the root collar diameter of seedlings from which the seed coat was removed was 3.38 mm. As a result of the growth characteristics according to the potting soil, 1- and 3-year-old Q. myrsinifolia seedlings showed excellent root growth in commercial potting soil and sand mixed potting soil. Consequently, seedling quality index was 0.124–0.257 according to irrigation and 0.149–0.262 according to potting soil. From observing the root growth of the seedlings according to the irrigation treatment, in the case of 3-year-old seedlings, the total root length was 432 cm when irrigated every 3 days, and the growth was the best. The above results are expected to contribute significantly to the mass propagation of Q. myrsinifolia, which is important for warming and urban greening.

“…In this regard, studies have been conducted on moisture control suitable for the specifications of each tree species for seedlings. However, it is not easy to investigate the quantification of irrigation amount by growth stage considering the physiology of trees [ 19 ]. In general, containerized landscape trees are ideally maintained in the soil within the containers so that all irrigation is applied to the trees.…”

The amount of irrigation and fertilization should be considered first for the production and standardization of high-quality H. syriacus L. seedlings using container seedlings. This study was conducted to investigate the optimal conditions suitable for container cultivation of hibiscus by analyzing growth and physiological responses according to the control of irrigation and fertilization. Therefore, in this study, H. syriacus L. for. Haeoreum (3-year-old hardwood cutting propagation), a fast-growing, was transplanted into a 40 L container. The irrigation amount per container was adjusted (0.2, 0.3 and 0.4 ton/yr/tree), and the amount of fertilizer applied (0, 69.0, 138.0 and 207.0 g/yr/tree). The growth rate according to the irrigation-fertilization treatment was higher in the 0.3 ton-138.0 g/yr/tree irrigation-fertilization treatment (p < 0.001). Total biomass yield and seedling quality index (SQI) were highest in the 0.3 ton-138.0 g/yr/tree irrigation-fertilization treatment (p < 0.001). The higher the fertilization concentration, the faster the flowering and the longer the flowering. The photosynthetic capacity of H. syriacus L. was reduced in bare root seedling cultivation and container-non-fertilized treatment. The chlorophyll fluorescence response was also affected by bare root cultivation and containerized seedling cultivation fertilization. Nutrient vector diagnosis showed “nutritional suitability” in the 0.3 ton-138.0 g/yr/tree treatment. Overall, containerized seedling cultivation was superior in growth, photosynthetic performance, photochemical efficiency, and nutrient storage capacity compared to bare root cultivation. These results be expected to contribute not only to the industrial production of excellent container seedlings of H. syriacus L. but also to the production of other woody plants.
