Which outcome results when an invasive plant species secretes abscisic acid in the soil?

💡 Explanation

When abscisic acid accumulates in the soil, neighboring plants experience increased activation of ABA receptors in guard cells triggering increased stomatal closure because ABA mediates abiotic stress responses hindering efficient gas exchange. Therefore heightened stomatal closure results, rather than increased chlorophyll, decreased auxin, or cambium formation, all of which involve different signaling pathways.
