O objetivo deste trabalho foi quantificar o florescimento e a produção de grãos de pinhão-manso (Jatropha curcas) em resposta à aplicação de benziladenina diretamente sobre inflorescências fechadas. O experimento foi realizado em campo, com plantas em idade produtiva, em cultivo adensado. Foram avaliados: número de flores femininas e masculinas por inflorescência, número de inflorescências e de cachos por plant...

Considering the importance of the culture of Coffea canephora in the Brazilian Amazon and the need for genetic improvement of this species for cultivation in the state of Rondonia, he objective of this study was to evaluate the correlation between the initial vigor of clonal plants of C. canephora variety Conilon, under field conditions, and its potential for in vitro propagation. Promising clones belonging to ...
A pupunheira é uma importante cultura amazônica em virtude da excelente qualidade do palmito, além de sua micropropagação ser de grande interesse para programas de melhoramento. O objetivo deste trabalho foi desenvolver protocolos para estabelecimento in vitro e indução de calos em explantes foliares de B. gasipaes submetidos a diferentes concentra&cc...
The cupuassu (Theobroma grandiflorum) stands out as an important recently domesticated Amazon fruit. Although the substrate is a prime factor for plantlet development, there are few recommendations for cupuassu plantlet production. The objective of this work was to evaluate the influence of different substrates on cupuassu germination and seedling growth. Seven substrates were tested in greenhouse conditions: v...
