Abstract:
Arundo donax L (Giant Reed) is a perennial grass widely used as energy crop. In general Arundo donax presents absence of sexual reproduction. In vitro culture or rhizome propagation methods have been predominantly used although they are unpractical and expensive. In order to facilitate its field implantation several experiments have been developed to obtain plants from vegetative multiplication of Giant Reed. The objective of this work is to analyze if there are differences in yield after two year field implantation of Arundo donax plants coming from different multiplication treatments. Plants were obtained from a previous experiment of multiplication. Stalkswere placed in trays or drums with water varying position (vertical or horizontal), number of nodes in and outside water. Plants from this experiment were established in field in Central Spainin randomized blocks. Two growing seasons after establishment aerial and subterranean biomass were evaluated.According to our results, best yields per plant (315g on average) do not correspond to higher plant productivity yield per area(1.6 kg m-2). Best results were shown in treatmentswith high survival rate during the field establishment. Low mortality rateisdeterminant in terms of productivity yield of the crop.
