Zhejiang Daxue xuebao. Lixue ban, 2003 以浙春3号大豆为研究材料,设置了不同的钼、硼水平,研究了钼、硼浸种对大豆种子的萌发和幼苗生理特性的影响.结果表明:低浓度钼或硼有利于大豆种子的萌发,钼、硼浸种时间以12 h最佳,钼浸种或不过量硼浸种将增加大豆幼苗的呼吸速率,提高过氧化物酶(POD)、过氧化氢酶(CAT)和超氧化物歧化酶(SOD)等抗逆性酶的活性,降低质膜透性(MP)及丙二醛(MDA)和脯氨酸(Pro)的含量,中等浓度的钼、硼浸种效果最显著,而高浓度硼浸种将产生相反的效果.

Integrative Conservation, Volume 5, Issue 2, Page 192-204, June 2026.We developed an effective ex‐situ conservation approach for an endangered orchid species, Dendrobium sinominutiflorum. A compatible fungal strain Tulasnella sp. was obtained by using in‐situ seed baiting technique. The Symbiotic germination with Tulasnella sp. significantly promotes seed germination and seedling growth.

Zhongguo shiyan zhenduanxue, 2020 阻生牙(impacted teeth)是一类由于其周围存在诸如邻牙、骨或软组织等阻碍物,而导致其仅能部分萌出或者完全不能萌出,并且以后萌出的概率也较低的牙[1]。下颌阻生智齿会造成牙列不齐,邻牙发生龋齿,冠周炎等并发症,影响美观。因此下颌阻生第三磨牙的拔除成为口腔颌面外科门诊最为常见的手术操作之一[2]。拔除下颌阻生第三磨牙的难度较大,极易引发术中及术后多种并发症的发生 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...

Functional Ecology, Volume 40, Issue 5, Page 1151-1164, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Ceramic reinforcement is crucial for crafting ultrastrong and wear‐resistant metallic components. However, pronounced stress concentration and strain incompatibility at ceramic–metal interfaces often trigger microcrack initiation and ceramic spalling exacerbating friction under sliding conditions.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Tungsten is inherently brittle and particularly prone to thermal stress concentration and crack formation during additive manufacturing processes such as laser cladding, which severely limits its engineering applications as a coating material. To address this issue, this study proposes an in situ toughening strategy involving the introduction ...
