The aim of this study was to investigate the effects of treating maize ( L.) seeds with fish collagen hydrolysate (FC) and keratin (KE) derived from animal waste by-products of leather and meat production, as well as poly(hexamethylene biguanide) hydrochloride (P) and bentonite (B). This research is in line with the search for new, environmentally friendly methods to increase yields of industrial crops in a way that is compatible with sustainable development. The effect of the binders used was investigated by analysing the grown maize seedlings by determining changes in parameters of chlorophyll fluorescence, photosynthetic pigments, elemental composition and FTIR analysis on maize shoots. The results indicated a slightly higher fresh weight (FW) of shoots in plants treated with fish collagen, PHMB and bentonite (FC+P+B) and FW of roots in plants treated with keratin, PHMB and bentonite (KE+P+B). Unexpectedly, the FW and dry weight (DW) of both roots and shoots of all bentonite-treated plants were significantly higher than the corresponding non-bentonite-treated groups. In addition, changes in chlorophyll-a fluorescence were observed for the keratin, PHMB and bentonite variants. This study showed that the proposed materials could be promising seed pelleting agents to improve seed growth and yield.
本研究旨在探讨用鱼胶原蛋白水解物（FC）和动物皮和肉生产副产物衍生的角蛋白（KE）、多聚（六亚甲基双胍盐酸盐）（P）和膨润土（B）处理玉米（Zea mays L.）种子的效果。这项研究符合寻找新的、环保的方法来提高工业作物的产量，同时与可持续发展相兼容。通过分析叶绿素荧光参数、光合色素、元素组成和 FTIR 分析，研究了所用粘结剂的效果。结果表明，用鱼胶原蛋白、PHMB 和膨润土处理的植株的苗鲜重（FW）和用角蛋白、PHMB 和膨润土处理的植株的根 FW 略高。出乎意料的是，所有用膨润土处理的植株的根和苗的 FW 和干重（DW）都明显高于相应的非膨润土处理组。此外，角蛋白、PHMB 和膨润土变体的叶绿素-a 荧光也发生了变化。本研究表明，所提出的材料可能是有前途的种子包衣剂，可以改善种子的生长和产量。
