摘要

摘要本研究旨在验证水稻优良基因型碳同位素组成与性状之间的相关性。对20个基因型进行形态学、显微形态学、解剖学、生理性能和碳指纹图谱分析。这些地块由500升的塑料箱组成，种植水稻，每平方米种植300株植物。利用显微镜和红外气体分析仪分别对植物解剖和生理性能进行了评估。水稻水分利用效率(r = 0.45)与羧化效率(r = 0.39)呈正相关。

Correlation between carbon isotopic composition and morphological, micromorphological, anatomical, and physiological traits in rice

Abstract The objective of this work was to verify the correlations between carbon isotopic composition and traits of superior rice genotypes. Twenty genotypes were analyzed for morphology, micromorphology, anatomy, physiological performance, and carbon fingerprint. The plots consisted of 500 L plastic boxes sowed with rice, to allow of a plant density of 300 plants per square meter. Plant anatomy and physiological performance were evaluated using a microscope and an infrared gas analyzer, respectively. There is a correlation between rice water use efficiency (r = 0.45) and carboxylation efficiency (r = 0.39).
