lühipäevased

Lühipäevased is an Estonian term referring to plants that flower or reproduce when the length of daylight decreases, typically in late summer or autumn. This photoperiodic response is crucial for their survival and reproductive cycles, allowing them to complete their life stages before the onset of winter. Many common garden flowers, such as asters, chrysanthemums, and dahlias, are lühipäevased. Agricultural crops like soybeans and rice also exhibit this characteristic, influencing their planting and harvesting schedules. The precise duration of daylight that triggers flowering can vary between species and even cultivars. This phenomenon is a vital adaptation, ensuring that seeds are developed and dispersed when conditions are most favorable for germination in the following spring. Understanding the lühipäevased nature of plants is essential for gardeners and farmers to optimize their cultivation practices.
