Leaf senescence can be described as the dismantling of cellular components during the terminal stage in the development of plant organs and tissues. In order to determine the leaf senescence process when stem girdling and leaf removal both exist. An experiment was carried out in Alhagi sparsifolia, which grew in the Cele oasis-desert transitional zone with(More)
Climate change is expected to result in an increase in the frequency and magnitude of extreme weather events. Alhagi sparsifolia is an important factor for wind prevention and sand fixation in the forelands of the Taklamakan Desert. The effects of high temperature on desert plants remain widely unknown. In this work, chlorophyll a fluorescence induction(More)
Alhagi sparsifolia Sharp. is commonly considered as a type of sun plant, but shade-grown plants cannot acclimate to the strong irradiance which is normal for plant in a short time when kept in low-light conditions for a while. Alhagi sparsifolia Sharp., commonly considered as a type of sun plant, is the main vegetation found in the forelands of Taklamakan(More)
Recently, a wide range of quantitative research on the identification of environmental flow requirements (EFRs) has been conducted. However, little focus is given to EFRs to maintain multiple ecosystem services in oasis areas. The present study quantifies the EFRs in oasis areas of Tarim Basin, Xinjiang, Northwest China on the basis of three ecosystem(More)
The removal of a ring of phloem, named girdling, is used for manipulating carbohydrate content above and below the girdle. To investigate the impact of girdling on leaf water status, an experiment was carried out in Alhagi sparsifolia Shap. and Karelinia caspica (Pall.) Less., which grew in the Cele oasis-desert transitional zone with the treatment of(More)
An trench profile method was used to study seasonal variation of root ecological characteristics of Alhagi sparsifolia Shap. seedlings under different irrigation treatments. The results indicated the following: (1) Root morphology: under excellent soil moisture conditions, A. sparsifolia seedlings developed many horizontal roots and root sprouts to compete(More)
Phloem girdling can cause decline of photosynthetic rate (Pn), and the reason for Pn decline had been attributed to the reduction of stomatal conductance (Gs) and end-product feedback inhibition. In order to explore the reason for Pn decline, the different stages of girdling—control, semi-girdling (SG), and full-girdling (FG)—were performed on Alhagi(More)
Senescence is both a highly controlled and a strictly regulated process that is gene dependent. To study the PSII reaction in different types of leaf senescence processes, stem girdling was performed on Alhagi sparsifolia to investigate the leaf status in the control, natural senescence, and girdling-induced senescence leaves. The results showed that during(More)
Clonal integration in rhizomatous and stoloniferous clonal plants has been studied for many years, but the mechanisms of clonal integration of root-derived plants remain largely unknown. Alhagi sparsifolia is a typical root-derived clonal plant in the extremely dry land of the Taklamakan desert, and it usually cannot reproduce sexually in natural and(More)
