摘要: Summary • We report the influence of a systemic irradiance signal, from mature leaves, on anatomical characteristics developing leaves. • A signal reduced was induced by growing tobacco (Nicotiana tabaccum) plants at high and then measuring effect shading leaves development new leaves. The reverse, increased low increasing leaves. • Stomatal pore length, stomatal density index, epidermal cell shape, size leaf were all influenced signal. These responses reversible with changing irradiance, except for length.
