Figure 1
Principal component analysis (PCA) of the shoot fresh mass (MFPA), shoot dry mass (MSPA), plant height (AP), number of leaves (NF), chlorophyll a content (Clor-a), chlorophyll b content (Clor-b), total chlorophyll content (Clor-T), root length (CR), stem length (CC), stem diameter (DC), root fresh mass (MFR) and root dry mass (MSR) of lettuce genotypes (09, 27, 38, 47, 110, 142, 167, 195, 253, 288, Luiza and Vanda) grown under hydroponic system. PC1: principal component 1; PC2: principal component 2. It is possible to verify a positive correlation between the characteristics evaluated with parallel arrows, negative correlation with arrows in opposite directions and no correlation with perpendicular arrows. Araras, UFSCar, 2019.
