11% of China’s flowering plant species had been classified as threatened based on the assessments of Chinese higher plants in 2013 and 202018,19,20. Revisions in the Red List Index reveal that the overall extinction risks for plants in China have not been alleviated21. Some studies suggest ...
This classification is based on various recently published phylogenetic analyses, and it is equivalent to "An ordinal classification for the families of flowering plants", as submitted for publication in the Annals of the Missouri Botanical Garden by the "Angiosperm Phylogeny Group". Several families ...
Precise timing of flowering in plants is critical for their growth and reproductive processes. One factor controlling flowering time is the cycle of light and darkness within a day, known as the photoperiod. Plants are classified into long-day, short-day, and day-neutral plants based on light ...
is classified as a short night plant because it flowers only if the night is shorter than eleven hours (its critical period), and the cocklebur is a long night plant because it flowers only if an uninterrupted darkness lasts more than 8.5 hours. Both of these plants will flower with ten-...
Today, flowering plants——known as angiosperms (被子植物)-are the most diverse group of land plants. The oldest angiosperm fossils SO far found are 135 million years old, and many researchers believe this is when the group originated. The fossil record suggests the group then became diverse 13...
The rapid diversification and high species richness of flowering plants is regarded as ‘Darwin’s second abominable mystery’. Today the global spatiotemporal pattern of plant diversification remains elusive. Using a newly generated genus-level phylogen

plants(including asters, potatoes, soy beans, goldenrod and cockleburs) flower when the length of uninterrupted darkness is longer than the species' specific critical period.Thus spinach is classified as a short night plant because it flowers only if the night is shorter than eleven hours (its ...
Commercial onion varieties are classified as short, intermediate or LD length varieties, depending on the minimum daylength that induces bulbing, and provides an indication as to the latitude where a particular variety can be grown1. For example, LD onions are grown in temperate regions where ...
