| Abstract: | Abstract Wheat (Triticum aestivum L.) trichomes influence wheat leaf rust (Puccinia recondita Rob. ex Desm.) germling elongation as a function of the external element (i.e. ‐ Ca, Si, P, CI) concentration. Basal cells of multicellular trichomes have a high Ca content; and, Ca2+ has been shown to inhibit elongation of primary roots. Evaluation of epicuticular wax composition in the intracellular areas of epidermal cells might explain the disorganized growth in those locations. |
