Adaptabilitat del fajol a localitats amb característiques agroclimàtiques diferents de les tradicionals

Buckwheat (Fagopyrum esculentum Moench) is a cultivated plant of great agronomic and alimentary interest due to the multiple uses of the crop and the high nutritive value of its seeds, which are very beneficial to human health. In this work has been studied the adaptive capacity of this plant in areas of Catalonia with very different climatic conditions than those usually cultivated. To carry it out, the crop was characterized from a phonological point of view. The experiment was made in four Catalan localities: Castelldefels, El Prat de Llobregat, Mosqueroles and Vila-robau. Were used five different plant materials: from Argentina, Batet de la Serra, Cal Pauet (Espunyoles), Vic and Corte Inglés (Chinese origin). In the plots of Castelldefels and El Prat de Llobregat were planted the seeds of Batet, Vic and El Corte Inglés. In Mosqueroles, in addition to the previous seeds, were planted the original from Argentina. In Vila-robau were planted material plant from Batet and Cal Pauet. The first three trials were done in rain fed conditions and the last one under irrigation. With the data obtained, we analysed the differences in growth of the materials within the same plot and among them. It was also evaluated if the irrigation influenced the growth of the crop or not. The results showed that the duration of the buckwheat productive cycle, as well as the achievement of the different phenological stages, differed between seed origins. Between the plant materials of the same trial, only statistically significant differences were found in Vila-robau, specifically in the stages of full flowering and beginning of fruit ripening. Regarding the materials sown in more than one plot, statistically significant differences were observed in the stages of third leaf, beginning of flowering and in the death of the plant of Vic seeds. From the seeds of Batet, statistically significant differences were observed between the trials of irrigation and dry land. These were in the first stages of development, between cotyledon and first leaf, and in the final stages of maturation. Between full flowering and the first brown fruits, there were statistically significant differences among the three localities. El fajol (Fagopyrum esculentum Moench) és una planta cultivada de gran interès agronòmic i alimentari gràcies als múltiples usos del cultiu i a l'alt valor nutritiu de les llavors, molt beneficioses per a la salut humana. En el present treball s'ha estudiat el grau d'adaptabilita
