A new sweet cherry rootstock cultivar 'Jingchun 2' was derived from interspecific hybrids of sour cherry(Prunus cerasus)and Chinese cherry (P. pseudocerasus). It is easy propagation and has very good grafting compatibility with most sweet cherry cultivars. 'Jingchun 2' could keep very slight injury ...

Human activities have increased the possibility of simultaneous warming and drought, which will lead to different carbon (C) allocation and water use strategies in plants. However, there is no conclusive information from previous studies. To explore C and water balance strategies of plants in...

Water use efficiency is among the most important eco-physiological strategies for species adaptation to water-limiting habitats. However, understanding of how co-occurring species adopt diverse water use strategies to cope with water- and resource-limited soil habitats via the adaptation of leaf...

Knowledge concerning the water use characteristics of revegetated species has profound implications for understanding soil-plant interaction mechanisms and guiding ecological restoration strategies in water-limited ecosystems. Although afforestation is an important way to improve ecosystem...

In order to investigate the response mechanism and salt tolerance of Chimonanthus praecox to salt stress, five-year seedlings of C. praecox 'Yipin Wanhuang' were potted for 40 d under 0, 0.3%, 0.6%, 0.9% and 1.2% salt stress. The growth, physiological and chlorophyll fluorescence parameters of C....

A coniferous trunk, Megaporoxylon sinensis sp. nov., is described from the Carnian-Norian (Triassic) Huangshanjie Formation in the Dalongkou section, Jimsar County, Xinjiang, northwestern China. The trunk is composed of pith, primary and secondary xylem. The pith is solid, circular, heterocellular, ...

Thin (3-6 cm) arborescent lycopsid axes that conform to the genus Sigillaria have been discovered upright in situ in the Wuda Tuff (Asselian: Inner Mongolia, China). Given that a broad lycopsid tree, Sigillaria cf. ichthyolepis, was the sole arborescent lycopsid taxon previously known from the...

A new whole-plant species of a calamitacean, Palaeostachya guanglongii sp. nov., is described in a volcanic ash bed from the Cisuralian (lower Permian) Wuda Coalfield, Inner Mongolia, North China. It was an approximately 2-3 m high shrub-like plant growing in a peat-forming swamp. It is...

The genus Tingia Halle is one of the most typical taxa of the Cathaysia Flora. However, its affinity, has long been uncertain. Tingia unita Wang 2006 was named based on the discovery of a crown of a tree that shows the organic connection of the simple compound leaves and the strobili with the stem. ...

In addition to soil water depletion, the degradation of revegetated sand-binding shrubs may be attributed to specific biological traits of the plant itself, such as aging. To improve our understanding of the physiological basis of observed age-related changes in photosynthetic capacity and water...
