Resumo
Os trabalhos práticos desenvolvidos foram realizados no Centro de Biotecnologia
de Plantas da Beira Interior (CBP-BI), situado no Campus da Escola Superior Agrária
de Castelo Branco (ESACB), tratando-se de uma infraestrutura do Sistema Científico e
Tecnológico Nacional.
O objetivo deste trabalho assenta no estudo e acompanhamento de diferentes
práticas desenvolvidas em estufa/viveiro de plantas e laboratório, no CBP-BI.
Primeiramente é abordado o conceito de propagação de plantas e quais os seus
tipos: Propagação sexuada/seminal e Propagação assexuada/vegetativa.
Foi desenvolvido um trabalho prático que consistiu na propagação de Manjerona
(Origanum majorana L.), através do método de propagação vegetativa por estacaria
utilizando estacas herbáceas terminais de 5 a 10cm de comprimento. Depois seguiu-se
o processo de repicagem, que consistiu no transplante das plântulas dos tabuleiros de
cuvetes para vasos, de modo a proporcionar um melhor desenvolvimento e
enraizamento.
Também foi feita uma caraterização da planta de Manjerona e identificação dos seus
principais usos, sendo esta planta medicinal, condimentar e aromática.
Outro trabalho prático desenvolvido consistiu na micropropagação de Pitaya
(Hylocereus undatus L.), das variedades 06 (Pitaya Royal Red) e 07 (Pitaya Jindu Nº1),
fazendo também referência ao meio de cultura utilizado para esta espécie, ao modo de
preparação e desinfeção dos explantes retirados da planta-mãe para depois ser
micropropagada e estabelecida in vitro.
Determinadas atividades são desenvolvidas diariamente na estufa/viveiro do CBP BI para a sua gestão e manutenção, como limpeza do espaço, irrigação das plantas,
podas, controlo do crescimento das plantas, remoção das plantas secas e reutilização
do substrato existente nos vasos destas mesmas plantas.
Também foi realizado um trabalho prático referente ao Projeto Cultivar, um projeto
de investigação sobre a Esteva (Cistus ladanifer L.), cujo principal objetivo é atribuir
valor para esta planta, sendo estudados e analisados vários aspetos relevantes
Abstract: The Plant Biotechnology Centre of Beira Interior (CBP-BI), a facility of the National Scientific and Technological System, is situated on the campus of the Escola Superior Agrária de Castelo Branco (ESACB), where the developed practical work was conducted. The aim of this project is to investigate and track various methods created in a lab and greenhouse at CBP-BI. First, the terms "plant propagation" and "asexual/vegetative" and "sexual/seminal" propagation are discussed. A practical work was created that involved using terminal herbaceous cuttings, measuring 5 to 10 cm in length, to propagate marjoram (Origanum majorana L.) through vegetative propagation. The next step was the transplanting procedure, which involved moving the seedlings from their trays into pots for improved roots and development. The marjoram plant, which serves as an aromatic, condiment, and medicinal herb, was also described and its primary use noted. Pitaya (Hylocereus undatus L.) varieties 06 (Pitaya Royal Red) and 07 (Pitaya Jindu Nº1) were the subject of another practical work that was developed. This work also included information about the culture medium used for this species and the process of preparing and disinfecting the explants that were taken from the mother plant in order to be micropropagated and established in vitro. Certain activities are carried out daily in the CBPBI greenhouse/nursery for its management and maintenance, such as cleaning, watering, pruning, managing plant development, eliminating dry plants, and reusing substrate in the pots of the same plants. Additionally, practical work was done in connection with the Cultivar Project, a study on the rockrose (Cistus ladanifer L.) with the primary goal of valuing this plant by examining and analyzing a number of pertinent factors.
