This study presents a novel way of enhancing plant growth through the use of a non-petroleum based product. We report here that exposing either roots or seeds of multicellular plants to extremely low concentrations of dissolved hydrogen sulfide at any stage of life causes statistically significant increases in biomass including higher fruit yield. Individual cells in treated plants were smaller (~13%) than those of controls. Germination success and seedling size increased in, bean, corn, wheat, and pea seeds while time to germination decreases. These findings indicated an important role of H2S as a signaling molecule that can increase the growth rate of all species yet tested. The increased crop yields reported here has the potential to effect the world's agricultural output.
本研究提出了一种通过使用非石油基产品来促进植物生长的新方法。我们在这里报告,在生命的任何阶段,将多细胞植物的根或种子暴露于极少量的溶解硫化氢中,会导致生物量的统计显著增加,包括更高的果实产量。处理过的植物中的单个细胞比对照植物的细胞小(约 13%)。在豆类、玉米、小麦和豌豆种子中,发芽成功率和幼苗大小增加,而发芽时间减少。这些发现表明 H2S 作为一种信号分子在增加所有已测试物种的生长速度方面起着重要作用。这里报告的增加的作物产量有可能影响世界的农业产出。
