寿命最长和最短的种子桉树种子是世界上寿命最长的种子。1985年11月,在澳大利亚新南威尔士的勃莱沃德附近,发现了一批1万年前冰河期遗留下来的极为珍稀的古桉树种子。最近,经澳大利亚国家植物园的研究人员用低温方法打破休眠,精心培育,终于有一粒种子长出了幼苗。橡胶树的种子是世界上寿命最短的种子,成熟后必须随即播种,否则在无水情况下只能存活几小时。但只要得到一点水、它便可在2—3小时内生根发芽。 Longest and shortest seeds Eucalyptus seeds are the longest-lived seed in the world. In November 1985, a group of rare ancient eucalyptus seeds left over from the glacial period of 10,000 years ago were found near Brive in New South Wales, Australia. Recently, researchers at the National Botanic Gardens Australia used cryogenic methods to break dormancy and carefully nurtured them. Finally, a seed grew seedlings. Rubber tree seeds are the seeds of the shortest life in the world and must be seeded immediately after they have matured or they can only survive for a few hours in the absence of water. But as long as you get a little water, it can take root in 2-3 hours.
