摘 要 ：研究分析了 C_3、C_4两类植物共60余个品种(基因型)的光合强度和光呼吸强度。结果表明,各类植物或同类植物不同品种问光合强度与光呼吸强度都有显著差异,但同类植物之间,光呼吸占总光合的比值比较稳定。C_3植物光呼吸/总光合比值约为25～35%左右,C_4植物其比值约为1～7%。二者比值几乎不受基因型、生育期的影响而改变。这一结

Abstract:The photosynthetic and photorespiratory rate of more than sixty va-rieties(genotypes)of C_3 and C_4 plants were measured and studied.Theresults indicated that there were notable differences in photosynthetic andphotorespiratory rate between the different types of plants and among di-fferent varietie
