Última Photosynthesis, Growth and Development of Tabebuia avellanedae Lor. ex Griseb. (Bignoniaceae) in Flooded Soil BABT Davanso,Viviane M.; Souza,Luiz A. de; Medri,Moacyr E.; Pimenta,José A.; Bianchini,Edmilson. Morphological, anatomical and ecophysiological modifications caused by flooding in the growth and development of Tabebuia avellanedae Lor. ex Griseb. (Bignoniaceae) were studied and correlated with tolerance to the excess of water in the soil. Three-month-old plants, grown in a greenhouse, underwent a period of 56 days of flooding and a post-flooding period. Photosynthesis rate and growth decreased in T. avellanedae when flooding duration increased. Though not much tolerant, plant adapted itself to short flooding periods. This relative tolerance was probably due to the capacity of T. avellanedae in developing structures which lessened flooding effects and promoted internal diffusion of oxygen from the aerial part to the roots, such as stem fissures,...

Juss. and T. pallida Sw. (Meliaceae) BABT Souza,Luiz A. de; Moscheta,Ismar S.; Mourão,Káthia S. M.; Silvério,Adriano. Morphological and structural features of flowers of Trichilia catigua A. Juss., T. elegans A. Juss. and T. pallida Sw. (Meliaceae) are presented here with the purpose to stimulate future reproductive and preservation studies of these brazilian native species. Anthesis occurred from April to August in T. catigua, January to May in T. pallida and September to January in T. elegans. Sepals and petals presented a papillose and pilose epidermis and a parenchymatous mesophyll. Male flowers presented pistillodes with abortive ovules and a staminal tube with tetrasporangiate anthers. Anther wall had a papilose epidermis, a fibrous endothecium, two middle layers and a secretory tapetum. Female flowers presented antherodes and bi - or tricarpellate syncarpous...

(Rutaceae) BABT Souza,Luiz A. de; Moscheta,Ismar S.; Mourão,Káthia S. M.; Rosa,Sonia M. da. Studies on the morphology and anatomy of the flower and anthesis of Metrodorea nigra St. Hill. (Rutaceae) showed perfect flowers, which occurred in panicle. The peak of the flowering was August and September. The anthesis was diurnal and the species presented protandrous flowers. The green sepals and the red petals presented papillose epidermis with stomata and parenchymatic mesophyll. The tetrasporangiate anther presented a papillose epidermis too, endothecium cells with secondary parietal thickenings, two middle layers and binucleate tapetum. The only pistil presented an ovary wall with nectariferous tissue and a meristematic ventral epidermis, a solid style and an inconspicuous stigma. The ovules were anatropous, bitegmic and crassinucelate and... Tipo: Info:eu-repo/semantics/article Palavras-chave: Metrodorea nigra; Rutaceae; Blossom; Anthesis; Protandry; Flower structure.

(Bignoniaceae) submitted at the flooding and the "Ethrel" and silver nitrate application BABT Davanso,Viviane M.; Medri,Moacyr E.; Souza,Luiz A. de; Colli,Sandra. Three-month-old Tabebuia avellanedae Lor. ex Griseb. (Bignoniaceae) plants cultivated in the greenhouse were submitted to 56 days of flooding and to "Ethrel" and silver nitrate applications to find out it’s capacity for morphological and physiological modifications to survive under flooding conditions and at which degree such responses were correlated with alterations in the ethylene level. Flooding and the "Ethrel" application caused growth reduction and epinasty in T. avellanedae and the application of silver nitrate lessened some these symptoms. Certain symptoms shown during flooding by this species and its ability to develop structures which lessen hypoxia effects, such as stem fissures and hypertrophied lenticels in the roots, modifications which...
