The complete life cycle of Triatoma flavida, weekly fed on hens, was studied at 28+/-2 degrees C and 80+/-10% RH. Aspects related to hatching, life span, mortality and feeding behavior for each stage of its life cycle were evaluated. The hatching rate observed for 100 eggs was 93% with an average incubation period of 27.2 days. Sixty-two nymphs completed the cycle and the mean egg to adult deve...

Matthiola incana (Brassicaceae) is an important ornamental plant, which is used as cut flower, pot plant, and landscape. Traditionally, it is propagated via seeds, but interest is given in vegetative propagation of parental lines as well as superior single plants. Micropropagation by organogenesis is an efficient in vitro propagation method for Matthiola incana. Starting from seeds, apical bud ...

Tissue culture is an attractive alternative for plant propagation. Micropropagation is a technique to ensure a constant and uniform source of ornamental plants. Matthiola incana is an important ornamental species mainly cultivate by seed. Matthiola incana seeds were germinated on solid MS medium without plant growth regulators. Shoot proliferation and root formation are possible using kinetin (...
