Abstract

Abstract:

【Objective】 To clarify the effect of Urtica laetevirens extracts on the growth and photosynthetic properties of wheat seedling.【Methods】 The wheat cultivar Heimai 2 were used to analyze growth and photosynthetic characteristics in response to different treatments with Urtica laetevirens water extracts of roots, stems and leaves at concentrations of 0, 20, 40, 60, 80 and 100 g/L.【Results】 The root aqueous extract promoted seedling length and dry weight of wheat seedling, the lower concentration of root extracts promoted root length, root dry weight and root-shoot ratio while high concentration of root extracts inhibitory effect.The stem and leaf extracts all inhibited the wheat seedling length, seedling dry weight, root length, root dry weight and root-crown ratio.With the increase of root extracts concentration, the Fv/Fm, Y(Ⅱ), Y(Ⅰ) and ETRⅠ value slightly then reach stability.The ETRⅡ and qP fluctuating changes NPQ and CEF decreased firstly then.Along with stem extracts concentration increase, the Fv/Fm, Y(Ⅱ), Y(Ⅰ), ETRⅠ, ETRⅡ and qP value were decreased significantly, while the NPQ and CEF were increased significantly.At concentrations of 80 g/L, the NPQ and CEF were 1.37 and 5.42 times that of the control, respectively.The leave extracts no significant between the treatment group and the control group the photosynthetic characteristics.【Conclusion】 The comprehensive analysis showed that root extracts promote wheat seedling growth by improving the electron transmission rate and light energy conversion efficiency of PSⅠ slightly.However, the stem extracts cause a certain degree of damage to the photosynthetic system of wheat leaves, and inhibit the growth of wheat seedling.This damage be relieved by strongly stimulating cyclic electron transport and forming non photochemical quenching.The leaf extracts show inhibitory effect on wheat seedling growth, while it has no significantly difference on photosynthetic properties of wheat leaves.

摘要：

【目的】研究宽叶荨麻不同部位提取液对小麦幼苗生长和光合特性的影响。【方法】以黑麦二号小麦为对象,研究宽叶荨麻根、茎、叶不同浓度的水提液(20、40、60、80、100 g/L)对小麦种子萌发和幼苗生长的影响。【结果】根部浸提液对小麦的苗长和苗干重具有促进作用,对小麦根长、根干重和根冠比为低促高抑;茎部和叶部浸提液对小麦苗长、苗干重、根长、根干重和根冠比均具有抑制作用。不同部位浸提液对小麦叶片光合特性表现为根部浸提液对小麦叶片Fv/Fm、Y(Ⅱ)、Y(Ⅰ)和ETRⅠ小幅上升后稳定,ETRⅡ和qP呈现波动变化,各处理组和对照无显著性差异,而NPQ和CEF呈先下降后上升的趋势;茎部浸提液对小麦叶片Fv/Fm、Y(Ⅱ)、Y(Ⅰ)、ETRⅠ、ETRⅡ、qP均呈现显著下降趋势,NPQ和CEF呈现显著上升趋势,浓度为80 g/L时,NPQ和CEF分别为对照组的1.37倍和5.42倍;叶部浸提液对小麦叶片光合特性指标在处理组和对照组间基本无显著性差异。【结论】根部浸提液在低浓度时可小幅提升小麦叶片PSⅠ电子传递速率,有效增加PSⅠ光能转化效率从而促进其生长;茎部浸提液使小麦叶片PSⅠ和PSⅡ同时受损从而抑制其生长,且这种损伤可通过强烈激发环式电子传递速率从而形成热耗散来对其进行保护;叶部浸提液对小麦幼苗生长呈现抑制效应,但在小麦叶片光合特性上表现不显著。
