Iron Chlorosis Susceptibility

Iron chlorosis susceptibility refers to a plant's predisposition to develop chlorosis (yellowing of leaves) when iron availability or uptake is impaired, commonly observed in cannabis cultivation under certain soil pH, nutrient balance, or environmental conditions. This trait is heritable and varies significantly across genetic backgrounds, with some lineages showing greater resilience to iron-deficient symptoms than others. The condition typically manifests as interveinal chlorosis on newer growth when iron cannot be adequately mobilized by the plant, despite soil iron presence. Breeders and cultivators track iron chlorosis susceptibility as a practical phenotypic marker relevant to cultivation performance across different growing media and regional soil compositions. Understanding this trait's genetic basis helps inform selection strategies for lines suited to specific cultivation envi

Breeders working in environments with alkaline soils or recirculating hydroponic systems often select against iron chlorosis susceptibility to improve cultivation stability and visual plant health. Conversely, mapping this trait aids in understanding nutrient transport genetics and may inform broader mineral homeostasis research across cannabis lineages.
