Nutrient Resorption

Nutrient resorption refers to a plant's ability to mobilize and relocate nutrients from older tissues (particularly leaves) back into growing points before senescence or harvest. In cannabis breeding, this trait influences how efficiently plants can cycle nitrogen, phosphorus, and potassium through their lifecycle, affecting both yield potential and nutrient demand during flower. Cultivars with strong resorption capacity often show delayed leaf yellowing and may require less supplemental feeding in later growth stages. Breeders working in this category track visual markers—like maintained canopy color and leaf vitality through late bloom—as indicators of nutrient efficiency. Understanding resorption is particularly relevant in organic and low-input cultivation systems, where nutrient availability fluctuates. This trait intersects with plant vigor, starch metabolism, and senescence timing

Breeders leverage nutrient resorption as a selection criterion to develop cultivars suited to resource-constrained environments and sustainable growing protocols. Plants with efficient resorption reduce total nutrient load requirements, lowering input costs and environmental footprint while maintaining productivity.
