Precocity of Spring Flowers [PDF]

open access: yesNature, 1913
THE effect of the mildness of the winter is shown in the number of wild plants now in flower, some of them evidently survivors from the autumn, others early spring flowers, and yet others entirely out of season. During a walk on January 3 and 4 from Brighton through Ditchling and Haywards Heath to Balcombe, we observed no fewer than thirty wild flowers

Possible involvement of spermidine and methyl jasmonate on sex expression and some physiological responses of cucumber [PDF]

open access: yesBMC Plant Biology
Background Sex expression in plants is a complex process influenced by genetic, environmental, and hormonal factors. In cucumbers, a high male-to-female flower ratio significantly contributes to low yields.

Vernalization: Spring into Flowering [PDF]

open access: yesDevelopmental Cell, 2006
Polycomb group protein (PcG) complexes mediate epigenetic processes in plants as well as in animals. We discuss recent progress in understanding the varied roles that Polycomb complexes play in the epigenetic control of vernalization-the promotion of flowering by extended exposure to low temperature.

Flower angle favors pollen export efficiency in the snowdrop Galanthus nivalis (Linnaeus, 1753) but not in the lesser celandine Ficaria verna (Huds, 1762)

open access: yesPlant Signaling & Behavior, 2023
Flower angle is crucially important for accurate pollination and flower protection against abiotic factors. Evolutionary factors shaping floral traits are particularly strong for bilaterally symmetric flowers because these flowers require more ...
