Table 3 in Protochlorophylls in Cucurbitaceae - Distribution, biosynthesis and phylogeny

Table 3 Composition of protopheophytins in the seed coats of the species and varieties of Cucurbitaceae under investigation and total protopheophytins/protochlorophylls ratios. The compounds are ordered according to increasing retention times in HPLC chromatograms.The data are the means of 3 replicates with SE ≤ 20% of the mean values.
