摘要: Immobility complicates mating by angiosperms because the transfer of male gametes between individuals requires pollen vectors. Although abiotic and biotic vectors can transport considerable distances (Bateman, 1941a; Squillace, 1967; Kohn Casper, 1992; Godt Hamrick, 1993), resulting pattern dispersal does not intrinsically maximize number quality matings. Consequently, floral evolution generally involves two classes adaptations that promote success. The morphological traits characterize design display modify actions so as to enhance fertility (see below). In contrast, physiological mitigate unsatisfactory rejecting unsuitable gametophytes (Jones, 1928; de Nettancourt, 1977; Marshall Ellstrand, 1986; Seavey Bawa, Barrett, 1988; Snow Spira, 1991; Walsh Charlesworth, 1992) or zygotes (Stephenson, 1981; Becerra Lloyd, Montalvo, 1992). As a result postpollination processes, realized simply mirror pollination (e.g., Campbell, also see Waser Price, 1993). However, these processes only filter incipient established during pollination, fundamentally determines maximum frequency diversity opportunities. role in governing scope for inextricably links systems.
