1902Encycl. Brit. XXV. 436/1 The pollen-tube normally reaches the apex of the embryo-sac through the micropyle (acrogamy or porogamy). 1905I. B. Balfour tr. C. E. von Goebel's Organogr. Plants II. 615 The micropyle in all porogamous plants evidently conducts the pollen-tube. 1950P. Maheshwari Introd. Embryol. Angiosperms vi. 183 The tube may enter the ovule either through the micropyle or by some other route. The former is the usual condition and is known as porogamy. Ibid. 184 Even in plants classed as porogamous, there are several modifications. 1965Bell & Coombe tr. Strasburger's Textbk. Bot. 631 The pollen tube may reach the micropyle and hence the embryo sac by traversing the cavity of the ovule at a point where it is commonly filled with mucilage (porogamy, Fig. 757). |
