- 摘要:
- 以红丁香的根、茎和叶为试材，采用石蜡、木材切片及导管离析方法，研究了红丁香解剖结构与其抗旱性的联系，揭示其结构植物学特征及其干旱适应性机理。结果表明：红丁香根具有很强的贮水能力，横向和纵向的输水能力也得到保证，茎在贮水、保水、加强输水以及失水后保护等方面也有很强的适应机制。叶的特殊结构不仅保证了红丁香的光合效率，保证植物同化作用的进行，还可阻止高温伤害和过度水分流失。红丁香根、茎和叶的解剖结构均具有明显的抗旱特征，说明红丁香具有极强的抗旱能力。
- Abstract:
- Taking root，stems and leaves of Syringa villosa Vahl as material，using paraffin section and method of segregation catheter wood，on the Syringa villosa Vahl anatomical structure and drought resistance of contact，in order to reveal the structure characteristics and mechanism of botanical drought adaptability.The results showed that the root of Syringa villosa Vahl had the water storage capacity was very strong，horizontal and vertical water capacity was also guaranteed，stem water in the water storage，water and water loss，strengthen protection after had strong adaptation mechanism.The special structure of leaves not only to ensure that the Syringa villosa Vahl photosynthetic efficiency，guarantee for assimilation of plants，could also prevent heat damage and excessive water loss.The structure of the root，stem and leaf of Syringa villosa Vahl lanatomy had obvious drought resistance characteristics，indicating that the Syringa villosa Vahl had strong drought resistance.
