The guard mother cell dormancy of soybean cotyledon

Abstract

The cotyledons of soybean seeds serve both as a food source and a photosynthetic organs for the early development of soybean seedlings. The development of the stomata of cotyledons should be important and related to the food source utilization and the mechanism of photosynthesis. During the study of the development of the cotyledon stomata of soybean seeds, a phenomenon was observed on the upper epidermal layer of the cotyledon, we call it. “the dormancy of the guard mother cell”, which is not reported in the literature available to us.Soybean seeds were soaked, planted and sampled at 24, 48, and 72 hours after planting. The upper epidermal layers were stripped with a sharp razor blade, and processed for observation with Hitachi S-2300 scanning electron microscope.
