The Formation of Girdle Scars & Leaf Scars |

 Winter twigs. The leaf scars on twigs are a characteristic shape for each species, the sealed vascular bundles making a pattern of dots in them. Since each leaf usually has a bud in its axil, there should be a lateral bud above each leaf scar. Earlier in the year, when the terminal bud was sprouting, the bud scales, unlike the foliage leaves, were not spaced out on the stem and when they fell off, they left narrow scars close together extending from a quarter- to half-way round the stem. These are commonly called 'girdle scars' and since they mark the position of each year's terminal bud, the length of stem between each set of girdle scars represents one year's growth. © Copyright D G Mackean |
