Anther cultures of maize

open access: yesBiologia Plantarum, 1977
The presence of synthetic auxins (2,4-D at a concentration as low as of 0.5 to 5.0 mg I-1, NAA at least at 5 mg I-1) in the cultivation medium was essential for the induction of callogenesis in anther cultures ofZea mays L. The application of IAA was ineffective.

Rediscovery of Passiflora clypeophylla (subgenus Decaloba): a highly threatened and narrow endemic species found within a karstic canyon in Guatemala

open access: yesNordic Journal of Botany, EarlyView.
Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a
