Resumo(s)
A Cannabis sativa L. tem vindo a ganhar destaque para fins medicinais e terapêuticos em
termos globais, e no nosso país é uma cultura que se encontra em expansão. Com a
necessidade de gerar novas plantas a partir do processo de macro propagação foi
decidido escolher uma variedade com baixa taxa de enraizamento e assim através de
uma análise comparativa, utilizando 8 tratamentos, procurou-se verificar qual o
tratamento com melhor taxa de enraizamento. Estes 8 tratamentos englobaram três
pressupostos diferentes: o tamanho do clone, a intensidade de luz a partir do quinto dia
de enraizamento e o Ec (condutividade elétrica) utilizado na fertirrega. Ao longo do
ensaio foi realizada a propagação dos trinta e três clones em cada um dos oito
tratamentos no respetivo tabuleiro de substrato e foram retiradas medições de cada
clone em dois momentos distintos, bem como observado o aparecimento de novas
folhas. A contagem do número de raízes observadas realizou-se em três dias distintos
de modo a obter um resultado mais concreto. Estes oito tratamentos foram feitos com
três repetições de modo a obter um resultado o mais fiável possível colocando os
tratamentos de forma aleatória no interior da sala, e após a recolha de todos estes dados
fazer a sua análise e obter uma conclusão. Após analisar os resultados e retirar as
conclusões de todos os tratamentos em comparação com o nosso testemunho, neste
caso o tratamento 6, é possível definir qual ou quais os pressupostos que tem influência
no enraizamento dos clones bem como no seu desenvolvimento.
Cannabis sativa L. has been gaining prominence for medicinal and therapeutic purposes globally, and in our country, it is a crop that is expanding. With the need to generate new plants from the macro propagation process, it was decided to choose a variety that is difficult to root and thus, through a comparative analysis using eight treatments, the aim was to determine which treatment had the highest rooting rate. These eight treatments encompass three different assumptions: the size of the clone, the light intensity from the fifth day onwards, and the Ec (electric conductivity) used in fertigation. Throughout the trial, the thirty-three clones were propagated in each of the eight treatments in the respective substrate tray, and measurements were taken of each clone at two different times, as well as observing the appearance of new leaves. The number of roots observed were counted on three different days in order to obtain a more concrete result. These eight treatments were performed with three repetitions in order to obtain the most reliable result possible, placing the treatments randomly inside the room. After collecting all this data, it was analyzed and a conclusion was reached. After analysing the results and drawing conclusions from all the treatments in comparison with our control, in this case treatment 6, it is possible to identify which factors influence the rooting of the cuttings as well as their development.
