Green Pak Choi is better in suitable environment but the purple ones more resist to drought and shading.

ABSTRACT:

Background

Studying how economic vegetable adapt to stressful environment is important not only for plant biology application but also to agronomy. In this study, we selected two commonly used genotypes of pak choi, i.e., larger green pak choi (Brassica rapa ssp. chinensis) and smaller purple pak choi (Brassica rapa var. chinensis, 'Rubi F1') to examine the divergent response of the two genotypes to drought and shading in the semi-arid region of Xinjiang. We compared the differences in biomass accumulation and plant morphological traits of the two pak choi in response to the interaction effects of drought (55-70% of field water capacity) and shading (24% reduction of canopy light radiation).

Results

The results showed drought and shading significantly reduced the aboveground
