Evolution from mixed to fixed handedness in mirror-image flowers: insights from adaptive dynamics

bioRxiv
Mirror-image flowers (enantiostyly) involve a form of sexual asymmetry in which a flower’s style is deflected either to the left or right side, with a pollinating anther orientated in the opposite direction.

Proximity-dependent Pollen Performance in Silene vulgaris [PDF]

, 2017
• Background and Aims Pollen and seed dispersal in herbaceous insect-pollinated plants are often restricted, inducing strong population structure. To what extent this influences mating within and among patches is poorly understood.

Effect of Crown Layers on Reproductive Effort and Success in Andromonoecious Aesculus indica (Wall. ex Camb.) Hook (Sapindaceae) in a Temperate Forest of Garhwal Himalaya

Plants
The andromonoecy is an unusual sex expression in trees in which an individual plant bears both functionally staminate and hermaphrodite flowers on the inflorescences.

Do they really hybridize? A field study in artificially established mixed populations of Euphrasia minima and E. salisburgensis (Orobanchaceae) in the Swiss Alps [PDF]

, 2018
Hybridization and introgression in the European species of Euphrasia depend on the relationships between the species, on flower size and habitat. Hybridization between Euphrasia minima and Euphrasia salisburgensis was investigated in their natural ...

Reproductive Biology of Calamus Manan Miquel [PDF]

, 1999
Adopting a plant improvement programme that combines silviculture and genetic improvement could increase yields of Calamus manan plantations. The silviculture of C. manan is well studied but not on the aspects of genetic improvement.
