Fuente: WIPO "tomato" The present invention introduces a novel non-hormonal formulation for plant yield enhancement and maximizing post-harvest shelf life, consisting of Pyrogenic acid/acetic acid or nitric oxide (NO) donors, such as sodium nitroprusside, to effectively extend flowering duration, enhance flowering uniformity, and improve crop yield and quality parameters like size, sugar content, shelf life. This composition uses Pyrogenic acid/acetic acid or nitric oxide (NO) donors, such as sodium nitroprusside as a plant signaling modulator to boost hormone response pathways, photosynthesis, and enzymes modulating shelf life. Unlike traditional PGRs and hormonal treatments, which often exhibit inconsistencies in field performance, this formulation provides a reliable, consistent outcome. It can be applied across various crops, improving productivity and sustainability while reducing reliance on synthetic plant growth regulators, offering a more environmentally friendly alternative.
