Autor: Silvia Aguilar Rodríguez, Teresa Terrazas, María Elena Huidobro-Salas, Ernesto Aguirre-León
Publikováno v: Botan‪ical Sciences, Vol 94, Iss 3 (2016)
Excessive growth of Tillandsia recurvata (ball moss) may impact host architecture and survival. For a better understanding of this effect, an anatomical and histochemical bark assessment was carried out in four host species. The PCoA (principal coord
