Abstract/Contents: | The vascular system of the young Italian ryegrass seedling is very similar to that of oats. Early accounts failed to record the distinctive separate course of the xylem and phloem constituents of the bundles at the coleoptilar node. The ascending mesocotylar trace is bicollateral and continues up, in part, into the mid-vein of the 1st foliage leaf and arches over, joining the bases of the 2 coleoptilar traces, to become the collateral scutellar trace. There was considerable variation from seedling to seedling in the details of the vascular pattern. This was coupled with additional variation in mesocotyl elongation, extent of the coleoptilar node, number and location of lateral root primordia and their maturation, rate of growth of coleoptile and 1st foliage leaves and the rate of vascular differentiation within them. Possible causes of this variability are discussed and it was noted that apparently identical plants, selected on a single morphological criterion such as degree of elongation of the coleoptile, would be expected to differ markedly in other morphological and anatomical aspects, influencing their performance in physiological experimentation. |
