“…There was also some variation among the lines in seed oil and protein content, TSW and onset of flowering but there was no clear division by previous breeding activities. These results deriving from greenhouse‐grown camelina lines are consistent with a previous study in a fully controlled chamber (Stasnik et al, 2022 ). The eight lines tested showed similar performance with Calena, Celine and Korneuburg having the highest yield while Kirgizskij, Rollsdorf and Gomholka showed a low yield but high dry matter biomass.…”

“…It is worth noting that plant height was comparable in both studies, suggesting that the differences in available resources did not significantly impact final plant height. The onset of flowering was accelerated compared to Stasnik et al (2022), which could be a result of the increased substrate and nutrient availability (Kumar & Chaudhary, 2018;McConnaughay & Bazzaz, 1991) and/or the different light and temperature conditions in the greenhouse (Goto et al, 1991;Thomas, 2006).…”

Climate change increasingly challenges agricultural production systems and thus food and bioenergy security. To meet this challenge, the climate-resilient, low-input, versatile Brassicaceae oilseed crop camelina (Camelina sativa [L.] Crantz) is a promising alternative species. Camelina, also known as gold-of-pleasure, false-flax, Siberian oilseed, German sesame and linseed dodder is native to Southeast Europe and Southwest Asia and

“…Carotenoids can not only assist plants in light absorption but also act as antioxidants to remove free radicals generated in photorespiration ( Cao et al., 2003 ). The test results showed that the high soil water content had an impact on the photosynthetic pigments of three coniferous leaves, and the contents of chlorophyll a, chlorophyll b and carotenoids in the leaves showed a downwards trend, which was similar to the previous research results of Paulownia forunei , Camelina sativa and cotton ( Liu X, et al, 2020 ; Zhang et al., 2021 ; Stasnik et al., 2022 ). The accumulation of active oxygen in conifers during hypoxic or anoxic conditions is believed to exacerbate the peroxidation of membrane lipids found in chloroplasts.…”

Study on the causes of growth differences in three conifers after the rainy season in the Xiong’an New Area

BackgroundThe implementation of the Millennium Forestry Plan was accompanied by growth discomfort exhibiting varying degrees of symptoms in some coniferous forests after the rainy season.HypothesisHigh soil water content affects the underground root growth and distribution characteristics of conifers, and the above-ground parts show corresponding variability. To determine the factors contributing to the significant growth disparities among the three conifers in Xiong’an New Area after the rainy season, we conducted a study investigating the growth characteristics of conifers. This study involved analyzing the external morphology of the plants, assessing leaf pigment content, measuring the root morphological index and root vigor, as well as respiratory characteristics, to evaluate the growth attributes of their root systems in a high soil moisture environment.MethodsIn the “Millennium Forest” area of Xiong’an New Area, we selected three coniferous trees, Pinus tabuliformis, Pinus bungeana and Pinus armandii, and set up three standard sample plots for each conifer. The conifers were classified into 3 levels according to their growth performance (vigorous or suppressed), leaf condition (color change, wilting or not) and relevant grading criteria.Results(1) The growth of the three conifers displayed discernible differences in external morphology. Moreover, a decrease in growth condition corresponded to a reduction in crown size, ground diameter, diameter at breast height, leaf length, and new growths. (2) The root biomass, length, surface area, and root volume of conifers growing N class were significantly reduced than those of L class conifers. Conifers with a higher proportion of root systems in the 40-60 cm soil layer experienced more severe stress. (3) The significant decline in root respiration and vigor among all three conifer growth classes (M and N) suggested that the root system was undergoing anoxic stress, particularly at a soil depth of 40-60 cm where root respiration and vigor were notably reduced. (4) The persistent anoxic stress created by long-term exposure to high soil moisture content primarily impacted P. armandii to a greater extent than P. tabuliformis and P. bungeana. Additionally, the transporting and absorbing root ratios varied among conifers with differing growth conditions. The long-term high moisture environment also caused partial death of absorbing roots, which played a key role in the observed differences in growth. (5) As the soil depth increases, the soil water content increases accordingly. Plants with more root distribution in the deeper soil layers grow worse than those distributed in the top soil layers. Soil water content is related to aeration, root distribution, growth and growth of above-ground parts. The variability of root distribution and growth led to the differentiation of the growth of the above-ground part of the plant in terms of external morphology, which inhibited the overall plant growth. The results of the study provide a theoretical basis for the cultivation and management of three conifers in high soil moisture environments.

“…Previous research has shown that the photosynthetic system of waterlogged peanut leaves was disrupted, which limits its ability to absorb CO 2 and decreased overall photosynthetic efficiency. The pod-filling stage was the most susceptible stage to waterlogging (Mitchell et al, 2013 ; Miransari and Smith, 2014 ; Ahmad et al, 2021 ; Stasnik et al, 2022 ). Waterlogging at this time drastically reduced the number and weight of pods per plant, which ultimately resulted in a decline in peanut productivity (Bishnoi and Krishnamoorthy, 1992 ; Zeng et al, 2020 ).…”

Peanut is among the main oil crops in India with huge economic importance. The unpredictable rainy season during the growing time of peanuts causes waterlogging in peanut fields. Waterlogging triggers major environmental limitations that negatively affect the growth, physiology, and development of peanuts. Thus, the export and production of peanuts are severely affected by waterlogging. Therefore, the understanding of metabolic mechanisms under waterlogging is important to future water-stress tolerance breeding in peanuts. This study aimed to evaluate how peanuts responded to various waterlogging conditions in terms of their development, metabolic processes, and chlorophyll fluorescence characteristics. The evaluations were carried out at different stages of peanut variety DH-86 treated with waterlogging. The peanut plants were subjected to different waterlogging periods of 20, 40, 60, 80, and 100 days. The growth parameters including total dry mass, total leaf area, and total leaves number were calculated in all treatments. The phenomenological and specific energy fluxes and maximum photosystem II efficiency (FV/Fm) were also determined. The measurements were done statistically using PCA, G-Means clustering, and correlation analysis to explore the interaction between different physiological parameters. The waterlogging for 100 days caused a significant reduction in the total number of leaves, dry mass, and total leaf area. The most sensitive parameters are specific and phenomenological energy fluxes and Fv/Fm, which notably decreased as waterlogging duration increased. The results indicated the growth and physiological performance of the peanut cv. DH-86 was affected significantly due to waterlogging and the interaction between all these parameters in waterlogging. This research focused on how peanuts respond to waterlogging stress and provides the basis for future plant breeding efforts to improve peanut waterlogging tolerance, especially in rainy regions. This will improve the sustainability of the entire peanut industry.
