Correlation between leaf number and environmental variables.

r values (Pearson) representing correlation between Leaf Number (LFN) values with environmental variables. Correlation coefficients are given for simulated shade and sun conditions and the ratio of LFN between these treatments (Shade/Sun). Correlation is between either accessions of all species or only accessions of S. arcanum and S. habrochaites. Note the negative correlation between developmental rate and NDVI values under each light treatment and in response to simulated foliar shade. Correlation becomes significant when only S. arcanum and S. habrochaites accessions are considered. *p
