“…Furthermore, no significant effect on root morphology was detected among combinations at the low-P supply, with a few exceptions (Figure 3). Because of the presence of P mainly in the upper layers of soil and decreasing with depth, root growth can be enhanced under P deficiency, especially with respect to the fine roots [48][49][50][51]. However, no effects were found in the current study, perhaps owing to our sampling only once for the whole experiment.…”

Grafting provides a way to improve tolerance to low phosphorus (P) stress for plants, and has been extensively applied in commercial cultivars grafted onto appropriate rootstocks. However, little literature is available concerning the scion-mediated effect on P efficiency in grafted plants. In this study, three different Camellia oleifera Abel. scion cultivars (G8, G83-1, and W2) were grafted onto the same rootstock (W2) under controls (0.5 mM) and low-P (0 mM) availability for eight months. The results showed that the scions significantly affected root-to-shoot weight ratios, the root morphology with a diameter larger than 1 mm, P accumulation, and the P utilization efficiency (PUE) of the root. A higher increase in the root-to-shoot weight ratio under the low-P supply was observed in the G83-1/W2 (26.15%) than in the G8/W2 (0%) and the W2/W2 (5.32%). Root PUE of the scion G8, G83-1, and W2 was improved by up to 113.73%, 45.46%, and 20.97% under the low-P supply. Moreover, G8/W2 exhibited higher shoot P accumulation and the highest root PUE under the low-P supply, indicating a high capability to tolerate P deficiency by maximizing the cost-effectiveness of P remobilization to photosynthetic organs. This suggested the vigorous variety of G8 could be a promising scion to improve grafted C. oleifera tolerance to low-P stress. Our results would have important implications for exploration and identification of a superior scion variety to enhance the ability of resistance concerning P deficiency stress in C. oleifera.

“…PRE may largely depend on P availability in soils [13,48]. For example, a negative correlation between PRE and soil P was found in planted forests [27,33,49]. Those results suggest that NRE and PRE are differentially regulated by climate and soil nutrient availability.…”

Nutrient resorption from senescing leaves is one of the plants’ essential nutrient conservation strategies. Parameters associated with resorption are important nutrient-cycling constraints for accurate predictions of long-term primary productivity in forest ecosystems. However, we know little about the spatial patterns and drivers of leaf nutrient resorption in planted forests worldwide. By synthesizing results of 146 studies, we explored nitrogen (N) and phosphorus (P) resorption efficiency (NRE and PRE) among climate zones and tree functional types, as well as the factors that play dominant roles in nutrient resorption in plantations globally. Our results showed that the mean NRE and PRE were 58.98% ± 0.53% and 60.21% ± 0.77%, respectively. NRE significantly increased from tropical to boreal zones, while PRE did not significantly differ among climate zones, suggesting differential impacts of climates on NRE and PRE. Plant functional types exert a strong influence on nutrient resorption. Conifer trees had higher PRE than broadleaf trees, reflecting the adaptation of the coniferous trees to oligotrophic habitats. Deciduous trees had lower PRE than evergreen trees that are commonly planted in P-limited low latitudes and have long leaf longevity with high nutrient use efficiency. While non-N-fixing trees had higher NRE than N-fixing trees, the PRE of non-N-fixing trees was lower than that of N-fixing trees, indicating significant impact of the N-fixing ability on the resorption of N and P. Our multivariate regression analyses showed that variations in NRE were mainly regulated by climates (mean annual precipitation and latitude), while variations in PRE were dominantly controlled by green leaf nutrient concentrations (N and P). Our results, in general, suggest that the predicted global warming and changed precipitation regimes may profoundly affect N cycling in planted forests. In addition, green leaf nutrient concentrations may be good indicators for PRE in planted forests.

“…Phosphorus is one of the most important factors influencing the growth and quality of plantations [35]. Despite few of the sites showed lower soil available phosphorous, there was a relatively similar amount of the nutrient at all the study areas ( Table 2).…”

This study was conducted at eight different cities and counties of Gyeongnam province with the objective of evaluating the suitability of lands for the growth of Chamaecyparis obtusa (C. obtusa) species. From each city and county seven to ten sites were systematically selected for the study based on the regional representation of the sample sites by considering south, east, west and north regions of the province. From the selected sites soil data was collected by removing the top fertile soil in order to avoid the influence of decomposed top organic materials on the top soil. Soil samples from each site were air dried and the necessary laboratory processes undertaken. Evaluation of physiochemical characteristics was conducted by analyzing the properties of soil with growth requirement of the species. Storie parametric and FAO land evaluation methods were adopted to evaluate the parameters which were identified as important for the growth of the species. Based on the total index resulted from the parametric evaluation, suitability class was defined by assigning classes of highly suitable, (S1), moderately suitable (S2), marginally suitable (S3) and non-suitable (S4). The results of the study revealed that two study city/county were moderately suitable and the rest were categorized under marginally suitable for the growth and productivity of the species but there was no site which was categorized as highly suitable and non-suitable. It was recommended to use more silvicultural management for the areas categorized under marginally suitable in order to enhance the productivity.
