Tolerance — Leaf Kale

Brassica oleracea L. (Kale Group)

The tolerance of leaf kale to abiotic stresses is defined by the quantitative preservation of productivity, physiological, and biochemical indicators under the influence of adverse factors.

In the reference 3 varieties crop Kale, where this is mentioned in the description.

The assessment of leaf kale tolerance to drought, overheating, and osmotic stress is based on the analysis of deviations from control values across a complex of parameters. Key biomarkers include the activity level of catalase, the concentration of proline, sugars, and glucosinolates, as well as the intensity of lipid peroxidation and the transcription level of specific adaptation genes, such as NAC, DREB, and heat shock proteins HSP70, HSP90.

Highly tolerant genotypes are identified by minimal reduction in biomass, preservation of root growth rates, and photosynthetic activity under stress conditions. This characteristic directly determines the stability of marketable leaf yield and the adaptability of varieties for cultivation in hydroponic systems with variable levels of osmotic pressure.
