GAsensitive

GAsensitive is a term used in multiple disciplines to describe sensitivity related to GA, an acronym that can refer to gibberellins in plant biology or to genetic algorithms in computer science. The term is not a standardized designation and its meaning depends on context.

In plant physiology, GA-sensitive refers to how strongly tissues respond to gibberellic acid (GA3) or other gibberellins. Sensitivity affects processes such as seed germination, stem elongation, leaf expansion, and flowering time. Variation in sensitivity can arise from differences in GA receptor availability, signaling pathway components, or metabolic status, and is commonly assessed with dose–response experiments and phenotypic measurements.

In evolutionary computation, GA-sensitive describes systems or problems whose outcomes are highly affected by genetic algorithm parameters. Researchers study sensitivity to population size, mutation rate, crossover strategy, and selection pressure to understand robustness and to guide parameter tuning. High sensitivity may indicate a need for adaptive or self-tuning GA configurations.

Because GA has multiple meanings, readers should infer meaning from context, and if possible consult source material to determine whether GAsensitive relates to plant hormones or to optimization algorithms.
