Figure 3:
Staining of tomato plant parts; root and collar region with fast green and safranin. (A) presence of R.H, root hair; Co, collenchyma; Pf, periphloematic fibers; Ep, epidermis; Cp, cortical parenchyma;(B) X1, primary xylem; X2, secondary xylem; Xf, xylem fibers; Am, amyloplasts;(C) P1, primary phloem; P2, secondary phloem; Cb, cambium;(D) whole healthy root section.
Figure 4:
Diseased samples stained with fast green and safranin. (A) Ty; Tylosis formation starts and vascular bundles disperse. (B) fusarium hyphae emerge from the branch. (C) dispersion of vascular bundles, tylosis occurring and disturbing the phloem. (D) full disintegrated cell portions and death of plant.
