Day neutral plant

From Wikipedia, the free encyclopedia

A day neutral plant does not require a specific day length to flower. It is neither a short day plant nor a long day plant.

Day neutral plants flower after attaining an overall developmental stage or age, or in response to alternative environmental stimuli, rather than in response to photoperiod.

[edit] Examples of day neutral plants:

• Cucumber (Cucumis sp.),
• Tomato (Lycopersicum sp.),
• Potato (Solanum tuberosum),
• Fava bean (Vicia faba),
• Rose (Rosa sp.).
• Maize (Zea mays, L.) - temperate zone cultivars - many tropical cultivars are short day plants.
