Thermal-biological aspects on the seed germination of Cucumis anguria L.: influence of the seed coat
Provedor de dados: Revista Brasileira de Botânica
Autores: SANTOS,DÉBORA LEONARDO DOS; CARDOSO,VICTOR JOSÉ MENDES.
The seed coat influences the early stages of germination of many seeds and sometimes maintains seed dormancy. Early reports have shown that the testa influences the germination response of Cucumis anguria seeds to light although the response to temperature as influenced by the tegument is not well understood. The main purpose of this study was to observe the influence of the testa on the germination of Cucumis anguria by using parameters as germinability and isothermal germination rate. The assays were carried out in a thermal-gradient block with water imbibed seeds kept in darkness. Estimates of the activation enthalpies (deltaH) show |deltaH| &lt; 50 kJ.mol-1 between 26.1 °C and 35.2 °C (intact seeds) and between 25.4 °C and 35.2 °C (scarified seeds),...

Preliminar report on the presence of tegumentar glands in the thorax of Meliponinae bees (Hymenoptera, Apidae)
Provedor de dados: Brazilian Journal of Biology
Autores: CRUZ-LANDIM,C.; REGINATO,R. D.
This is a first report on the presence of glandular cells in the lateral tegument of the mesothorax of Meliponinae bees. The cells are of the insect class III glandular cells and are present in queens, workers and males. The glands are more developed in queens than in workers, and in workers than in males.
