11 Ιουν 2004 · INTRODUCTION. Stamens are the male reproductive organs of flowering plants. They consist of an anther, the site of pollen development, and in most species a stalk-like filament, which transmits water and nutrients to the anther and positions it to aid pollen dispersal.
1 Απρ 2002 · Flowering plants are predominantly hermaphroditic, with most species producing flowers that contain both female (pistils) and male (stamens) sexual organs.
26 Ιουν 2021 · The anther is the pollen producing part of the stamen, which is supported by a stalk-like filament, and together, they make up the male reproductive structure of the angiosperm flower.
1 Σεπ 2005 · This paper defines a new organ-identity function. The SEPALLATA genes (SEP1, SEP2, SEP3) function with the class A, B and C floral-organ identity genes to specify petal, stamen and carpel...
1 Ιουν 2004 · This review integrates ultrastructural and developmental findings with recent models for self-assembly in an attempt to understand the origins of the morphological complexity and diversity that underpin the science of palynology.
24 Μαρ 2016 · Obdiplostemony is the consequence of shifts in the balance between the two stamen whorls, affecting either the alternisepalous stamens together with the petals, or the antesepalous stamens.
Pollen, anther, stamen and androecium visual signalling is a precondition for PASAM (Osche 1983; Lunau 2000) and its striking diversity is illustrated by some meaningful examples in nature (Fig. 3). Stamens represent the sole visual signal of flowers in Acacia retinodes (unpublished; Fig. 3A).
