PEKyN (CyHAN)- A "full-standing multiflorous chrysanthemum" grafted in central China's Henan Province has earned its place in the Guinness Book of World Records for containing the largest number of chrysanthemum species.
The multiflorous chrysanthemum is 3.8 meters in diameter and composed of 641 different types of chrysanthemums grafted to southernwood.
The spikelets of naked oat are distinctively different morphologically from hulled oat and this unique spikelet is referred to as a multiflorous spikelet (Valentine, 1995) or for extreme multiflorous cases, a "chevron-type" spikelet (Burrows, 1986).
Although oat kernel size is primarily of interest because of dehulling conditions, persistent interest in the use of naked oat for human food, since it would not require dehulling, stimulates interest in the influence of the multiflorous spikelet on kernel size variation.
1), consistent with the multiflorous spikelet with loosely adhering lemma and palea, as described by Burrows (1986).
It is interesting that many naked oat genotypes, which are known for their multiflorous spikelets (Valentine, 1995), had frequencies of single-kernel spikelets greater than that of the hulled oat cultivars.
