“…In addition, we found increases in the J-I phase and positive K-band formation only in trees under thinning without liming or P. Increases in the J-I phase and positive K-band formation are considered indicative of stress in plants (Frydenvang et al 2015, Luo et al 2016. Changes in the J-I phase have been associated with responses of plants under low phosphorus availability, and K-band formation is normally observed in plants subjected to stress factors such as increased temperature (Sengupta et al 2013, Carstensen et al 2018a. However, plants under other stress factors, such as high irradiance, water and nutrient limitation, are also associated with alteration of the shape of the J-I phase and positive K-band formation (Cendrero-Mateo et al 2015).…”

“…Plants in high light environments may increase initial fluorescence (F0) and reduce all the induction phases (O-J, J-I, and I-P), and show a much flatter curve (Kalaji et al 2012), which may result in the formation of a positive K-band in O-J step, indicating more severe stress. The effects of P deficiency on OJIP curvature seem contradictory and nonspecific, but it was reported that under low P, the curvature of the OJIP transient is affected at around the I-step at 20 to 50 ms that gradually straightens and might be absent (Carstensen et al 2018a).…”

Phosphorus (P) fertilization and liming can reduce negative effects caused by a sudden increase in light availability after thinning of forest plantations. In this study, immediately after thinning, photochemical performance (quantum yield of PSII and performance index) decreased, however, liming and P fertilization reduced the negative effects caused by thinning and accelerated the recovery of Bertholletia excelsa trees. After thinning, the remaining trees increased J-I phase with the formation of a positive K-band which occurred exclusively in unfertilized (no liming or no P) individuals. Additionally, enhanced effective dissipation (DI0/RC) values (140%) were found in individuals without liming or P after thinning, while plants under liming and P increased DI0/RC values by 47 and 79%, respectively. Photochemical performance of B. excelsa was positively correlated to iron, zinc, and manganese. Thus, P fertilization and liming are recommended for alleviating the stress caused by high irradiance after thinning in B. excelsa plantations.

“…The electron transport rates and light-use efficiency can be reduced by P deficiency [19], which also lowers the fraction of leaf N allocated to the photosynthetic machinery [46]. Several studies found that P deficiency could cause detectable fluctuations of the kinetic parameters of photosynthetic fluorescence [47][48][49]. Except in summer and autumn, F v /F m and Y(II) were increased significantly under N60+P20 treatment, indicating an enhanced potential activity of PSII and a significantly increased proportion of open PSII reaction centers, which elevated the photosynthetic electron transfer capacity of the PSII reaction center and led to increased photosynthetic efficiency.…”

Phosphorus (P) deficiency in soil affects plant growth and primary production. Accelerated nitrogen (N) deposition can cause ecological carbon:nitrogen:phosphorus (C:N:P) stoichiometry imbalance and increase the degree of relative P deficiency in the soil. However, it remains unclear how N deposition affects P uptake and C:N:P stoichiometry in coniferous timber forests, and whether P addition diminishes the effect of N-induced P limitation on plant growth. From January 2017 to April 2018, we investigated the effects of nine different N and P addition treatments on 10-year old trees of Chinese fir, Cunninghamia lanceolata (Lamb.) Hook. Our results demonstrated that N and P additions at a high concentration could improve the photosynthetic capacity in Chinese fir by increasing the chlorophyll content and stimulating the photosynthesis activity. The C:N:P stoichiometry varied with the season under different N and P addition treatments, indicating that N addition at a moderate concentration could diminish the effect of the P limitation on the growth of Chinese fir. The soluble sugar content in the leaves displayed more stable seasonal variations, compared with those of starch. However, the non-structural carbohydrate (NSC) content in the leaves did not vary with the season under both P and N addition treatment. The data suggested that N and P combination treatment at moderate concentrations promoted carbon assimilation by accelerating the photosynthetic rate. Thus, our results provide new insights into the adaptation mechanisms of coniferous timber forest ecosystems to the effects of N deposition under P deficiency and can help to estimate the ecological effects of environmental changes linked to human management practices.

“…This knowledge of physiology can be used to determine crop needs and to ensure optimal timing of fertiliser applications. An example of this is presented by Carstensen et al (2018b) who were able to prevent irreversible damage to seedling growth, tiller development and grain yield in spring barley by using chlorophyll a fluorescence measurement to correct P deficiency by application of P fertilizer.…”
