Abstract

As plastic use shifts from non-degradable to biodegradable materials, the effects of biodegradable plastic fragments on crop physiology remain unclear. This study investigated how biodegradable plastic fragments influence maize development, transpiration, and defense signaling. Among five plastic types tested, poly(butylene adipate-co-terephthalate) (PBAT), polyhydroxyalkanoates (PHA), polycaprolactone (PCL), polylactic acid (PLA), and thermoplastic starch (TPS). PBAT and TPS showed the most significant effects and were selected for further oxylipin analysis. Results indicate that biodegradable plastic fragments can alter oxylipin signaling pathways in subtle but meaningful ways, suggesting that these materials are not inherently risk-free alternatives to conventional plastics.
