Study on Photosynthetic Characteristics of Diploid and Tetraploid Paulownia australis
摘要
Abstract
The photosynthetic characteristics of one -year-old diploid and tetraploid Paulownia australis leaves were deter-mined by Li-6400 portable photosynthesis system .The results indicated that tetraploid Paulownia australis had the same photosyn-thetic rule as diploid Paulownia australis; but the net photosynthetic rate ( Pn ) , stomatal conductance ( Gs ) , transpiration rate (Tr) and intracellular CO2 concentration (Ci) of the former were higher than those of the latter in various months .The diurnal vari-ations in the Pn, Gs and Tr of both diploid and tetraploid Paulownia australis showed single-peak curve in May, July, September and October , but those were bimodal in June and August .The change in Ci revealed a single -valley curve .关键词
