A Cypripedium plant was discovered in Wangqing County, Changbai Mountain, Jilin Province. This newly of not only inhabits the same natural habitat as calceolus L. and × ventricosum Sw. but also has a morphology intermediate between that C. ventricosum. Its dorsal sepals, petals, synsepal are similar to those calceolus, while color its lip is For purpose distinguishing from other plants, we provisionally named it W1. To further verify taxonomic status W1, introduced three identified forms...
Iris typhifolia Kitag is a perennial herbaceous species with high ornamental and applied value. Elucidating the mechanism of saline–alkali tolerance in crucial for their promotion areas. Saline–alkali stress one factors that affects plant growth, which has become significant global issue. In this study, we measured physiological biochemical indexes I. typhifolia, through germination potting trials, to evaluate resistance different levels artificial (0, 50, 100, 150, 200 mmol·L−1). The...
Drought is a major environmental factor limiting plant growth and development. Hemerocallis middendorffii perennial herbaceous with high drought resistance, ornamental application values. Understanding the mechanism of stress resistance in H. helpful for better utilization resources selection excellent germplasms. In this study, phenological physiological traits were comprehensively analyzed under natural (ND) PEG-simulated (PD), to different levels was evaluated. ND treated using water loss...
(±)-Hypersines A-C (1-3), the three pairs of enantiomerically pure monoterpenoid polyprenylated acylphloroglucinols with an unprecedented 6/6/5/4 fused ring system, were isolated from Hypericum elodeoides. Their structures, including absolute configurations, elucidated by comprehensive spectroscopic data, single-crystal X-ray diffraction, and quantum chemical calculations. The plausible, biosynthetic pathway 1-3 was proposed. Moreover, bioactivity evaluation indicated that 1a might be a...
Floral phenology and features are intricately linked to pollinator behavior pollination systems. Iris setosa is one of the ornamental irises family Iridaceae with beautiful flowers leaves, little research has been reported on its biology. This study analyzed how phenology, floral features, breeding systems, visits affect reproductive success I. populations in Jilin Province. Field observations studies demonstrated that reached bud stage late May, an average flowering time 30 days. The...
The growth and development of Cypripedium macranthos Sw. are affected by environmental factors, such as temperature, humidity, soil type, its crown density. In this study, morphological attributes, physiological traits, interactions with factors were analysed. results indicate that the C. was limited elevated density, alkaline-hydrolysed nitrogen, available potassium concentration. Moreover, attributes variably suppressed high density nitrogen concentration, whereas enhanced concentration...
采用机械合金化和热处理相结合的方法制备了MgB2化合物；采用振动式高能球磨机进行球磨，研究了磨球尺寸、球磨时间、热处理温度、保温时间等对合金化效果的影响，获得了最佳制备工艺参数。结果表明，在保持磨球质量与粉末物料质量比不变的情况下，采用大尺寸不锈钢球（Φ10 mm）代替小尺寸球（Φ2 mm，Φ5 mm），可以提高球磨时的撞击能量，加速Mg-B粉末的机械合金化；热处理温度不宜超过Mg的熔点，否则Mg粉易发生氧化和挥发；热处理保温时间越长，对产物MgB2物相形成越有利；MgB2的最佳制备工艺参数为：Mg粉和B粉按摩尔比1:2混合，球磨介质为Φ10 mm的不锈钢球，磨球质量与粉末物料质量比20:1，球磨时间12 min，再将粉末在真空管式炉中进行热处理，升温速率为5℃/min，并在580℃下保温10 h。
