宁杞1号与宁菜1号叶片解剖结构及营养成分含量的比较研究

目的]为枸杞的果用、莱用提供理论依据。方法]以宁杞1号与宁菜1号的成熟叶片为材料，制片，观察并测量叶片解剖结构。同时测定了叶片中的营养成分含量。结果]宁杞1号的上表皮、栅栏组织、海绵组织的厚度显著大于宁菜1号，分别增加2．07、15．96、7．71μm。宁杞1号的叶片平均厚度比宁菜1号厚8．50μm。宁杞1号的下表皮平均厚度比宁菜1号薄0．54μm。宁杞1号的维管束直径平均长度比宁菜1号短1．57μm。宁杞1号叶片中粗蛋白、粗纤维、热量的含量低于宁菜1号，而碳水化合物、钙离子、尼克酸及Vc的含量较宁菜1号高。结论]宁杞1号与宁菜1号的叶片结构及营养成分含量均存在较大差异。

Comparative Study of Leaf Anatomy and Nutrient Components of Ningqi 1 and Ningcai 1

Objective] The aim was to provide the theoretical basis for fruit use and edible use of Lycium barbarum.Method] With the mature leaves of Ningqi 1 and Ningcai 1 as tested material,the slice of leaves was prepared to observe and measure leaf anatomic structure and the nutrients content was also measured.Result] The thickness of epicuticle,palisade tissue,spongy tissue of Ningqi 1 was obviously bigger than that of Ningcai 1,increasing by 2.07,15.96,7.71 μm resp.The average leaf thickness of Ningqi 1 was thicker by 8.50 μm than that of Ningcai 1.The average hypodermis thickness of Ningqi 1 was thinner by 0.54 μm than that of Ningcia 1.The average length of vascular bundle diameter of Ningqi 1 was shorter by 1.57 μm than that of Ningcai 1.The content of crude protein,crude fiber,heat in Ningqi 1 leaves was lower than that in Ningcai 1,while its content of carbohydrate,calcium,niacin and Vc was higher than that in Ningcai 1.Conclusion] There were big difference in leaf structure and nutrient components of between Ningqi 1 and Ningcai 1.
