    Abstract

    Continuous cropping (CC) obstacle is a major threat in legume crops production; however, the underlying mechanisms concerning the roles allelochemicals play in CC obstacle are poorly understood. The current 2-year study was conducted to investigate the effects of different kinds and concentrations of allelochemicals, p-hydroxybenzoic acid (H), cinnamic acid (C), phthalic acid (P), and their mixtures (M) on peanut root growth and productivity in response to CC obstacle. Treatment with H, C, P, and M significantly decreased the plant height, dry weight of the leaves and stems, number of branches, and length of the lateral

    Effects of Two Potential Allelochemicals on the Photosystem II of Nitzschia closterium and Monostroma nitidum

    Bowen Huang, Enyi Xie*, Yu Ran, Xinyi Chen, Yongjian Huang, Jianjun Cui*

    Phyton-International Journal of Experimental Botany, Vol.92, No.1, pp. 251-269, 2023, DOI:10.32604/phyton.2022.022672 - 06 September 2022

    Abstract In aquaculture, high-density seaweed farming brings higher economic benefits but also increases outbreaks of diatom felt. The effective control of diatom felt in high-density seaweed farming has always been a research hotspot. This study selected two potential allelochemicals 2-hydroxycinnamic acid and quinic acid to explore their effects on a diatom Nitzschia closterium and an economic seaweed Monostroma nitidum. The results showed that 2-hydroxycinnamic acid had better inhibitory effects than quinic acid on the growth, pigment content and photosynthetic efficiency of N. closterium. Their half-maximal inhibitory concentrations at 120 h (IC50–120 h) were 0.9000 and 1.278 mM, respectively. Additionally, these… More >

    Sustainable Utilization of Agricultural Straw for Harmful Algal Blooms Control: A Review

    Kokoette Effiong1, Jing Hu1, Caicai Xu1, Tao Tang1, Haomin Huang2, Jiangning Zeng1,3, Xi Xiao1,3,4,*

    Journal of Renewable Materials, Vol.8, No.5, pp. 461-483, 2020, DOI:10.32604/jrm.2020.09111 - 29 April 2020

    Abstract The use of agricultural straw for algal bloom control has been studied for more than 30 years. In this article, we have reviewed the promising potentials of using agricultural straw as source of anti-algal agents, including the effectiveness of each major straw type so far used in this regard, and the investigated algal species. Various pre-treatment methods have also been widely reviewed. Signifi- cant progress has been made in natural product chemistry and molecular biology with regards to agricultural straw, especially in relation to the extraction of antialgal allelochemicals, degradation processes of agricultural straws and More >
