“…A pronunciada agregação nos eventos fenoló-gicos observada pode, segundo Murali & Sukumar (1994), ocorrer com freqüência em florestas tropicais sazonais. Para as espécies estudadas, as épocas de floração e de frutificação sobrepuseram-se, demonstrando o rápido desenvolvimento do fruto.…”

-(Flowering and seed rain in a secondary forest in São Paulo, southeastern Brazil). Flowering and seed rain in a secondary forest in São Paulo, southeastern Brazil, were studied through the collection of reproductive material obtained from seed traps of 0.5 x 0.5 m. Collections were made on a monthly basis between January and December, 1993. Ninety species belonging to 37 families were identified in the collected reproductive material. Seasonal flowering and fruiting patterns were observed in the forest. The majority of the species flowered from September; peaks in the flower and fruit abundance were observed in November. The flowering pattern was the same observed in other forests of the region, but the fruiting pattern was more seasonal. From the seed rain, it could be deduced that the anemochorous species dispersed their seeds mainly in November, at the onset of the rainy season and not in the dry season as was expected. The majority of zoochorous species dispersed their seeds during the middle of the rainy season, with a peak in January, when the conditions for fruit ripening, seed dispersal and seedling establishment were optimal. The largest quantity of seeds was produced by the lianas while the group of trees was the richnest in species.RESUMO -(Floração e chuva de sementes em mata secundária em São Paulo, SP). O florescimento e a chuva de sementes foram estudados em trecho de mata secundária em São Paulo, SP, através da coleta de material reprodutivo depositado em peneiras de 0,5 x 0,5 m, recolhido mensalmente entre janeiro e dezembro de 1993. Foram identificadas 90 espécies pertencentes a 37 famílias. Observaram-se padrões sazonais de floração e de frutificação, sendo que a maioria das espécies floresceu a partir de setembro, com picos de floração e de frutificação em novembro. O padrão de floração encontrado foi o mesmo verificado em outras florestas da região, sendo o de frutificação mais sazonal. Na chuva de sementes, as espécies anemocóricas dispersaram propágulos predominantemente em novembro, no início das chuvas e não durante a estação seca, como esperado. A maioria das espécies zoocóricas liberou propágulos durante o meio da estação chuvosa, com pico em janeiro, na época de melhores condições de amadurecimento do fruto, dispersão de sementes e estabelecimento de plântulas. As lianas produziram a maior quantidade de propágulos, enquanto das arbóreas obteve-se o maior número de espécies.

“…Os frutos autocóricos, apesar de não terem mostrado aqui nenhum padrão nítido, por serem na maioria dos casos explosivos, são adaptados à deiscência durante os meses mais secos, quando a umidade relativa é baixa (Murali & Sukumar 1994).…”

“…Rainfall and water availability have often been identified as the main factors controlling the phenological rhythms of tropical vegetation (Murali & Sukumar, 1994;Sorg & Ronner, 1996;Williams et al, 1999;Singh & Kushwaha, 2005). This paper describes the first findings from a detailed phenology of plants in the ultramafic maquis of New Caledonia and reveals community-wide patterns of flowering and fruiting.…”

“…The reproductive phenology of some of these forests has been extensively studied at the individual, population and community level 6,14,15,17 . However, in the southern parts of Asia, especially India, relatively few phenology studies have been conducted in tropical wet evergreen and dry deciduous rainforests 13,18 . At present and to the best of our knowledge, there is no reliable and long-term information on community-level reproductive phenology of tropical montane evergreen rainforests.…”

“…Knowledge of how climate change and evolutionary constraints affect flowering and fruiting patterns is critical because it provides useful insight and in-depth understanding for monitoring plant responses to environmental change and for predicting its consequences on ecosystem functioning 19 . In South India, a majority of tropical wet evergreen and dry deciduous rainforest species exhibit annual flowering patterns due to regular reproductive cycles 13,18 . However, studies predict that climate seasonality might shape community-level flowering frequency within this region.…”

Reproductive phenology in tropical forests has been potentially influenced by climatic cues, biotic interactions and phylogenetic constraints at the community level. Studies on this relationship in the tropical montane evergreen forest of south India are rather lacking. We made reproductive phonological observations on 497 individuals falling under 66 species, in 52 genera and 31 families, at weekly intervals for a period of three years from January 2002 to December 2004 consecutively. At the community level, most of the woody species had annual rhythm and showed regular seasonal reproductive cycle. Flowering and fruiting patterns were significantly related with climatic variables, seasonal patterns were significantly associated with biotic factors and further found that closely related species of flowering and fruiting showed similar in times at climatic seasonality. Therefore the study suggests that community level reproductive phenology was influenced by climatic variables, biotic interaction and evolutionary perspectives.
