The increased resistance displayed by humans to certain chemicals used in agriculture has boosted the demand for natural products in recent years. Innovative technologies and unique matrices have been used to develop products that can improve the efficiency of plant nutrient utilization in response to this problem. The creation of environmentally benign organic materials known as biostimulants, which stimulate plant growth by improving the efficacy of chemical fertilizers, is one method of raising agricultural output. Plant biostimulants are chemicals and/or microorganisms that, when applied to crops in small doses, can boost plant growth and production, improve product quality, and increase resource efficiency. Humic compounds, protein hydrolysates, seaweed, plant extracts, and helpful microbes are examples of biostimulants. These substances have been proven to affect plant metabolism, increase productivity, and increase plant tolerance to environmental stresses. As a result, scientific studies are needed to determine the processes that biostimulants activate.

  • Effects of Two Potential Allelochemicals on the Photosystem II of Nitzschia closterium and Monostroma nitidum
  • 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 allelochemicals… More
