- 摘要:
- 为研究干旱胁迫对垂盆草生长和光合特性的影响，以垂盆草为试材，设置4个不同干旱处理（干旱时间为1、3、6、9 d）测定在不同水分条件处理下垂盆草的生长发育状况和叶绿素荧光特性。结果表明：随着干旱程度的加剧，垂盆草植株的叶片总数、比叶面积、叶厚、株高、根长等生长指标数值显著降低；根干质量、茎干质量、叶干质量和总生物量显著降低；叶生物量比和比叶面积明显降低，茎生物量比显著上升，根生物量比无明显变化；叶绿素含量先上升后下降，在轻度干旱时（持续干旱3 d）达到最大值，重度干旱时（持续干旱9 d时）含量最少；PSII最大光化学量子效率(Fv/Fm)、电子传递速率(ETR)、光化学猝灭系数(qP)显著下降，而非光化学猝灭系数(NPQ)随干旱程度加剧显著上升。垂盆草植株干旱条件下，生长发育受到抑制，轻度干旱下垂盆草幼苗的光合能力表现出一定的适应性，而重度干旱则对幼苗光合作用影响较为严重。
- Abstract:
- In order to study the effects of drought stress on the growth and photosynthetic characteristics of Sedum sarmentosum,taking Sedum sarmentosum as test material,four different drought treatments (1，3，6，9 days) were set up to determine the growth and chlorophyll fluorescence characteristics of Sedum sarmentosum under different drought conditions.The results showed that with the increase of drought degree，the total number of leaves，specific leaf area，leaf thickness,plant height and root length decreased significantly.Root dry weight，stem quality，leaf dry mass and total biomass decreased significantly.Leaf biomass ratio and specific leaf area were significantly reduced，stem biomass ratio increased significantlyand root biomass ratio did not change significantly.Chlorophyll content first increased and then decreased，reached the maximum in mild drought (continuous drought 3 days)，and the lowest in severe drought (continuous drought 9 days).The maximum photochemical quantum yield (Fv/Fm)，electron transport rate (ETR)，and photochemical quenching coefficient (qP) of PSII decreased significantly，while the non-photochemical quenching coefficient (NPQ) increased significantly with the degree of drought.Under drought conditions，the growth and development of Sedum sarmentosum plants were inhibited，the photosynthetic capacity of Sedum sarmentosum seedlings showed some adaptability in mild drought，while the severe drought had a serious impact on seedling photosynthesis.
