Oligocarrageenan Foliar Spray Promotes the Growth and Yield of Pechay (Brassica rapa ssp. chinensis) under Postflooding Stress
This study demonstrates that applying a 240 ppm oligocarrageenan foliar spray as a curative treatment significantly mitigates post-flooding stress in pechay, leading to substantial improvements in growth, biomass, and a 769% increase in yield compared to untreated flooded controls.
