Phytochrome is the plant pigment which participate in several developmental processes regulated by light. In recent years this pigment has been associated with the detection of the environmental conditions but there is still a gap of information concerning the physioecological role of the pigment. In this paper the knowledge of the role of phytochrome on seed photoblastism is analysed based on several recent works done on the subject mainly with pioneer rain forest plants from Los Tuxtlas, Veracruz.

The behaviour of avian visitors to 23 species of subtropical Australian rain forest plants was observed in the Lamington and Border Ranges National Parks on the Queensland/New South Wales border to determine potentially important seed dispersers, seed predators and fruit thieves.

Seeds of 11 very small-seeded species with different degrees of shade tolerance as juveniles were tested for their response to neutral shade (6% daylight), green shade (3%), and darkness. Germination was monitored over 46 weeks. All species germinated in daylight to some extent. Species of Pternandra and Urophyllum, commonly found as juveniles in deep shade, germinated to the same percentage in green shade as in daylight, although over a longer time period, and to a lower percentage in the dark. Percentage germination of Gynotroches axillaris and Pellacalyx saccardianus, also found as juveniles in deep shade, was similar in all treatments, but much faster in daylight. Species of Ficus, which are found commonly as seedlings in deep shade but require higher irradiance for onward growth, germinated rapidly in daylight, and to a lower percentage and after a longer time in green shade than in the dark. Melastoma, which establishes in large gaps, germinated only in daylight. As most species can germinate under a spectral composition similar to canopy shade it is likely that they can germinate under a closed canopy in nature and may become established without the formation of even a transient canopy gap provided leaf litter is absent. Keywords: germination, red/far-red ratio, shade tolerance, tropical rain forest.
