Decomposed litter is an important soil amendment for enhancing regeneration through promoting nitrogen (N) and phosphorus (P) uptakes and utilizations. It is necessary to detect key soil attributes that contributed to this positive effect for regenerations in pine plantations. In this study, in-situ soils and litter were collected from local Chinese pine (Pinus tabuliformis Carr.) plantations (objective) and secondary forests dominated by Liaodong oak (Quercus liaotungensis Koidz.) (control). Soils were used for culturing one-year-old Chinese pine and Liaodong oak seedlings with a prolonged photoperiod in a greenhouse. Litter was composted with effective microorganisms and mixed to soils at ratios of 0% (control), 25%, and 50% (v/v). Compared to the control, the 25% ratio decreased shoot height and root-collar diameter, and the 50% ratio decreased the comprehensive seedling quality. Decomposed litter addition reduced shoot biomass and P content in pine seedlings and utilizations for N and P in both species. Multivariate linear regression indicated that high pH in growing media impaired root P content and biomass increments in shoot and root parts, and high organic matter content inhibited N content and concentration in shoots. Overall, the addition of decomposed litter resulted in overdoses of nutrient supply for both species. Our results contradict the argument that N and P released from decomposed litter are both beneficial for regenerations in plantations, neither did in secondary forests.","PeriodicalId":19364,"journal":{"name":"Notulae Botanicae Horti Agrobotanici Cluj-napoca","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138980164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the Chow test, which measures of structural breaks, the effects of COVID-19 on cotton production and trade were examined. According to the Chow test results, the pandemic had no significant effect on cotton production, exports and imports in the People’s Republic of China and Türkiye, while being highly influential on cotton production and exports in the U.S. and Brazil. Distinctively, in Pakistan, it had a significant impact on cotton production and import. It was observed that although the demand, trade and prices for cotton were descended, the cotton prices started to recover with the increase in demand in the third quarter of 2020. In June 2022, the highest peak in cotton prices was observed. As a conclusion, it is shown that cotton production and trade during the pandemic were affected in all countries except People’s Republic of China and Türkiye. However, the marks of the effects of factors such as decreasing stocks, uncertainties in national economies, high inflation and increase in production costs on the cotton economy will be better understood in the coming years.","PeriodicalId":19364,"journal":{"name":"Notulae Botanicae Horti Agrobotanici Cluj-napoca","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138985599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is mandatory to develop the effective measures to mitigate the adverse impacts of these stresses for ensuring sustainable crop productivity and food security. Therefore, a pot experiment determined the effects of brassinolide application, inoculation with AM fungi (Funneliformis mosseae) and their combined use on the growth, photosynthesis and antioxidant system of Leymus chinensis under saline-alkali stress (0, 150 mmol/L). The mechanism of the two to alleviate the saline-alkali stress of L. chinensis was explored. The physiological and biochemical indexes of Leymus chinensis were significantly affected under saline-alkali stress (150 mmol/L). Inoculation of AM fungi and application of brassinolide effectively increased the biomass accumulation in the upper part (∼ 25-40%) and root (15-35%) system of L. chinensis under saline-alkali stress. Further AMF also improved photosynthetic pigments (chlorophyll a, chlorophyll b), photosynthetic rate (Pn), Intercellular CO2 concentration (Ci), stomata conductance (Gs), transpiration rate (Tr), chlorophyll fluorescence antioxidant enzymes (SOD: superoxide dismutase. CAT: catalase APX: ascorbate peroxidase, GR: Glutathione reductase) activity, and decreased malondialdehyde (MDA: ∼ 40-50%) and hydrogen peroxide (H2O2: ∼ 30-40%) accumulation.

Consequently, it is crucial to effectively cultivate and maintain spinach's quality. Light plays a pivotal role in the growth and development of plants, including spinach, where different light qualities can influence its morpho-physiological traits and overall quality. To explore this, an experiment was conducted, using three distinct LED lighting sets for spinach cultivation. Light 1 emphasized blue light, Light 2 served as the standard white light control, and Light 3 focused more on red light with occasional brief UV-C flashes. Additionally, mild water deprivation was induced using 2.5% polyethylene glycol (PEG). The results revealed that using a high red-to-blue light ratio with intermittent UV-C radiation significantly reduced various growth parameters of spinach, such as root length, shoot length, root volume, fresh and dry root and shoot weight, as well as total and relative chlorophyll contents, when compared to the control group. Furthermore, water deprivation had a negative impact on spinach's growth, affecting shoot and root length, and fresh and dry weight in all light qualities, proving to be fatal under Light 3 conditions. Therefore, it is essential to carefully select appropriate light qualities throughout the plant's life cycle to enhance the quality of spinach, especially when mild water deprivation is involved. Opting for a higher blue-to-red light ratio was found to be somewhat beneficial in improving the overall quality of spinach.","PeriodicalId":19364,"journal":{"name":"Notulae Botanicae Horti Agrobotanici Cluj-napoca","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139262975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, we present an updated identification key for differentiating species within the Curcuma subgenus Hitcheniopsis in Thailand.","PeriodicalId":19364,"journal":{"name":"Notulae Botanicae Horti Agrobotanici Cluj-napoca","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139264305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
