Defining correct dormancy class matters: morphological and morphophysiological dormancy in Arecaceae

Dormancy in Arecaceae diaspores is due to underdeveloped embryos, therefore, morphological dormancy or morphophysiological dormancy. Consequently, claims such as external seed structures inhibit germination, embryos are fully developed at maturity, and underdeveloped embryo is not a form of dormancy are rejected, because embryo size of the diaspore at the time of dispersal was not taken into consideration. The re-classification proposal for moving morphological dormancy into non-dormancy is also discouraged. This is owing to the fact that when both morphological dormancy and non-dormant seeds are placed under conditions suitable for germination, those with morphological dormancy do not germinate immediately due to time needed for growth of the embryo, whereas non-dormant seeds can germinate quickly. The implications of correctly defining dormancy class are important, for researchers working with seeds at various levels from forestry to molecular biology.

定义正确的休眠类别事项:槟榔科的形态和形态生理休眠

槟榔科水杨石的休眠是由于胚胎发育不全,因此,形态休眠或形态生理休眠。因此,诸如外部种子结构抑制萌发、胚胎在成熟时完全发育以及发育不全的胚胎不是休眠形式等主张被拒绝,因为没有考虑分散时硬水铝石的胚胎大小。也不鼓励将形态休眠状态转变为非休眠状态的重新分类建议。这是因为当形态休眠的种子和非休眠的种子都放在适合发芽的条件下时,形态休眠的种子由于胚的生长需要时间,不会立即发芽,而非休眠的种子可以很快发芽.
