Somatic metaphase chromosomes and idiograms of Luffa species (2n = 26) stained with Giemsa (A, D, G), DAPI (B, E, H) and CMA3 (C, F, I) A–C L. acutangula D–F L. aegyptiaca cylindrica G–I L. echinata. Arrows indicate satellited chromosomes in Giemsa plates and CMA+ve signals in C, F, I. Corresponding somatic idiograms (haploid set) of: J L. acutangula K L. aegyptiaca L L. echinata, showing DAPI+ve (blue) and CMA+ve (golden yellow) bands. Scale Bars: 5 µm
