据《Scientia Horticulturae》的一篇研究报道(http://dx.doi.org/10.1016/j.scienta.2014.08.009),来自意大利博洛尼亚大学的Brunella Morandi等人研究了叶片气体交换和水分关系对AbbéFétel梨(Pyrus communis L.)树的果实日生长模式和维管流的影响。研究人员连续两年于一定的间隔时期内检测了AbbéFétel梨树的叶、茎水势日变化模型,叶片气体交换(净光合、气孔导度和蒸腾作用)、果实生长、维管(木质部和韧皮部)和蒸腾流。结果表明,叶片气体交换在早上较强,此时由
According to a study by Scientia Horticulturae (http://dx.doi.org/10.1016/j.scienta.2014.08.009), Brunella Morandi et al from the University of Bologna, Italy, studied the relationship between leaf gas exchange and water content Effect of fruit daily growth pattern and vascular flow on AbbéFétel pears (Pyrus communis L.) tree. The researchers tested the leaf and stem water potential diurnal variation models of AbbéFétel pear trees for two consecutive years at regular intervals, gas exchange (net photosynthesis, stomatal conductance and transpiration), fruit growth, vascular (xylem and phloem) And transpiration flow. The results show that leaf gas exchange in the morning strong, this time by
