MEASUREMENT OF DIAMETER OF FLOWER-BEARING STEM OF GLADIOLUS
The stem of the gladiolus has sufficient strength, which allows plants to firmly maintain a vertical position even in high winds. The maximum thickness of the stem in a leafless state is noted in the ‘Rozoviy Feyerverk’ variety (1.37 cm) when studying gladiolus plants grown from corms of the Extra category. In general, in varieties, larger corms give a significant increase in the thickness of the flower-bearing stem, which allows these varieties to increase a more powerful spike.
