皎洁的月光下,月季含羞绽放,在朦胧如纱的幻影中,显得格外娇艳,当你有心上前攀折,却不当心被茎上着生的刺扎破了手指——尽管有着柔弱的外表,花儿也常会给不速之客一个难忘的教训。事实上,在进行野外观察和采集植物标本活动的过程中,我们常常发现许多植物都带有刺,这些刺有的是植物体表结构外突形成的,有的是器官变态形成的;有的刺生在茎干,有的刺生在叶柄,有的刺生在果实上;它们的作用也各不相同,保护植物、抵抗干旱、攀援作用、帮助传播种子等等。这些现象都体现了植物刺的类型丰富多样性,也体现了带刺植物在长期进化发展中对环境的适应性。为了帮助读者认识这些带刺植物,本文根据植物刺的发育来源、 Under the bright moonlight, the blooming rose of the rose is especially tender in the shadow of the hazy yarn. When you are ready to climb, you are not careful to break your finger with a stab on the stem - despite its delicate appearance, Flowers often give an unforgettable lesson to uninvited guests. In fact, during the field observation and collection of plant specimens, we often find that many plants have thorns. These thorns are formed by outcrops of plant surface structures, and some are organically deformed. Dried, some thorn in the petiole, and some thorn in the fruit; their role is also different, the protection of plants, drought resistance, climbing, to help spread the seeds and so on. These phenomena all reflect the abundant diversity of plant prickles and the environmental adaptability of prickly plants in the long-term evolution. In order to help readers understand these prickly plants, according to the source of the development of prickly plants,
