Characterizing genotype specific differences in survival, growth, and reproduction for field grown, rapid cycling Brassica rapa
چکیده انگلیسی

Rapid cycling Brassica rapa (RCBr) develops rapidly, and has both small adult size and a brief life cycle. Yet, in spite of many investigations using RCBr, extremely few plant ecologists have used this plant in the field. This study is the first to describe the genotype specific variation in traits describing survival, growth, and reproduction for field grown, RCBr. I also identify traits associated with fitness. Five genotypes of RCBr were used: standard, anthocyaninless, yellow-green, anthocyaninless and hairless, and anthocyaninless and yellow-green. Plants were grown outside in a “common garden”. Eight plant traits were measured: life span, height, growth rate, leaf size, number of flowers and fruits, fruit set, and fitness. All traits, except life span, differed significantly among the five plant genotypes. Correlation analysis revealed that fitness increased as each of these of seven plant traits increased. This study demonstrates that RCBr can serve as a model organism in ecological field studies.
