| Noccaea caerulescens (J. & C. Presl) F. K. Mey (Brassicaceae) is a plant widely used in studies of the high accumulation of such metals as Cd, Ni, and Zn. Considered a biennial species, propagated mainly by seed, it presents a long period for the generation of new individuals, which significantly hampers the development of new studies of this species. Based on the above, the objective of this work was to develop a protocol to induce early flowering and abundant seed-production in N. caerulescens. Plants of this species were therefore grown and developed in a controlled environment (growth room and cold chamber), and then submitted to different treatments composed of combinations of the following environmental conditions: photoperiod (8 or 12 hour... |
