Research ArticleOpen accessPhrase in the titleAnalysis of Photosynthetic Pigment Content and Leaf Structure of Pteroceltis Tatarinowii Mutant with Yellow LeafYongchang Yu, Chen Lv, Min Liu, Tiantian ChenThe relationship betweenleaf variation characteristics and leaf structure characteristics of Pteroceltistatarinowii with yellow leaf was explored to provide a theoretical basisfor the breeding of other ornamental plants. In this study, the differences inpigment content, leaf structure, and chloroplast ultrastructure in leaves of Pteroceltistatarinowii mutant with yellow leaf 'Huiguang' and its original species'Lingyansi No. 1’ were studied. The results showed that … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 20 Sep 2022 · 5,598 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNitric Oxide Treatment Improves the Antioxidant Capacity While Inhibiting Anthocyanin Biosynthesis of Peach Fruit (‘Xiahui-8’) During RipeningZiqi Wang, Yanyan Li, Yingling Deng et al.Nitric Oxide (NO) is an important bioactive signal molecule that plays an important role in diverse physiological processes. This study aimed to explore the effects of Nitric Oxide (NO) treatments on postharvest peach fruit. Specifically, we examined changes in quality attributes, antioxidant ability, and anthocyanin profiles during storage, given the important role of NO as a bioactive signal molecule in … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 14 Apr 2026 · 1,392 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Fertilization Frequency and Amount on the Chemometric Characteristics, Physiology, and Yield of Tomato Under Substrate CultivationEnling Ji, Qianqian Di, Qingjie Du et al.This study examined the effects of fertilization frequency and quantity on growth, yield, and quality of tomatoes under substrate cultivation. A factorial experiment evaluated two fertilization frequencies (every 5 or 10 days) and three fertilization levels (15.69, 31.38, or 62.76 kg·ha⁻¹), along with an unfertilized control. Plants were assessed for growth and development, photosynthetic pigment content, gas exchange parameters, nutrient … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 16 Feb 2026 · 1,715 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBlack Tea Extract on the Preservation of Cantonese SausageHuan Cheng, Ying Liu, Dan Wu et al.Black Tea Extract (BTE) is a natural pigment with strong antioxidant activity. Its effect on the preservation of Cantonese sausage was investigated based on polyphenol components analysis in this study. The content of tea polyphenols in BTE was 26.61% by using spectrophotometry, the tea catechin in BTE was analyzed by HPLC, which included gallic acid (0.27%), caffeine (5.75%) and 8 … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 3 Sep 2020 · 6,728 accessesView PDF Cite

Research ArticleOpen accessIn the abstractASCORBIC ACID FOLIIAR SPRAY COUNTERACTING EFFECT OF SALINITY ON GROWTH, NUTRIENTS CONCENTRATIONS, PHOTOSYNTHESIS, ANTIOXIDANT ACTIVITIES AND LIPID PEROXIDATION OF BEAN (PHASEULUS VULGARIS L.) CULTIVARSZeinab A. Salama, El-Zanaty A.A. Abou El-Nour, Mohamed M. El Fouly, Alaa A. GaafarA water culture experiment was carried out in the Department of Fertilization Technology at National Research Centre, Cairo, Egypt, to investigate the effect of Ascorbic Acid (AsA) foliar application and salinity stress (100 ppm and 100 mmoL NaCl) on growth, nutrients concentration and some biochemical parameters of two kidney bean (Phaseulus Vulgaris L.) cultivars. Salinity caused significant reduction in growth … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 16 May 2014 · 7,900 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCharacteristic Study of the Marine Algae Sargassum sp. on Metal AdsorptionA. Saravanan, V. Brindha, Soundarajan KrishnanProblem statement: Biomass of brown marine macro algae is a biological resource that is available in large quantities and can form a good base for the development of biosorbent material. Approach: Algae have been found to be potentially suitable biosorbents because of its cheap availability, both in fresh or salt water, relatively high surface area and high binding affinity. Results: … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 7,660 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordLead Phytotoxicity Induced Changes in Biochemical Markers in Germination and Seedlings in Durum Wheat Triticum durum Desf. Cv.Vitron and GtaSoraya Slimani, Mokhtar Boudelaa, Saddek Abdelmadjid et al.Among the heavy metals most commonly found on land, lead is a strongly represented pollutant in soil and sediments. It is easily absorbed and accumulated in different parts of plants. On the macroscopic scale, lead causes unfavorable effects on plants. First and in the event of excess, it may exert toxicity affecting several stages of germination development in leaf formation … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 6 Sep 2017 · 7,480 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEffects of Some Heavy Metals in Some Morpho-Physiological Parameters in Maize SeedlingsSali Aliu, Bekim Gashi, Imer Rusinovci et al.Nowadays the heavy-metal pollution of the soil is causing ever greater problems, exacerbated by the fact that the heavy metals accumulated in plants may, either directly or indirectly, find their way into animals and human beings. Maize is one of the world’s most important crops, ranking third after wheat and rice, so the changes induced by one of the most … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 1 · 18 Mar 2013 · 8,430 accessesView PDF Cite
