WebMar 19, 2024 · For drought stress, when the plants reached the five-leaf stage, 12 tomato seedlings with different trichome characteristics were used as the experimental materials, and the water content of the potted soil was controlled by the weighing method to 75%–80% of the maximum water content. WebStomata (sing.-stoma) are very minute openings found in the epidermal layer of leaves, stem and other aerial parts of the plant. Each stoma remains surrounded by two kidney-shaped or bean-shaped cells called guard cells. Chloroplasts are always present in the guard cells. The inner wall of each guard cell is thicker while its outer wall is thinner.
