Global Change Biology, Volume 32, Issue 7, July 2026.Grassland recovery following nutrient cessation is asymmetric and strongly shaped by nutrient enrichment history. Higher nutrient addition rates and longer enrichment duration caused larger departures from control conditions, with biomass recovering more rapidly than species richness over decadal timescales.

Biodiversity as a Dominant Force in Shaping Ethnic Music Styles 生物多样性:塑造民族音乐风格的主导力量
Integrative Conservation, Volume 5, Issue 2, Page 236-245, June 2026.Our findings show that plant, bird, and mammal diversity considerably shape musical features such as vocal range and ornamental sounds, more so than geography or lifestyle. Our study provides the first empirical evidence linking biodiversity to ethnic music styles. Protecting biodiversity, the musical and cultural will be protected.

Zhejiang Daxue xuebao. Lixue ban, 2012 应用离体黄瓜子叶节花芽分化实验系统，研究了 PP333在黄瓜花芽分化进程中的作用.组织培养结果显示，0. 3 mg• L-1 PP333处理显著促进离体黄瓜子叶节培养物的花芽分化，直接花形成率由对照的16. 86%升高至36. 02%, 直接花芽/总芽的比值达到最高，约为对照的1.7倍；营养芽形成率和营养芽/总芽的比值均降至最低，分别为对照的72%和59%.组织切片结果显示，0.3 mg • L-1 PP333处理明显提高黄瓜子叶节培养物的花芽原基百分率和花芽原基/总原基的百分率，增幅分别为42%和50%

四川大学学报. 自然科学版, 2009 采用液体振荡培养的方法进行秋花独蒜兰原球茎的快速增殖和分化试验,分别研究了不同基本培养基、激素种类及其浓度、不同天然添加物对原球茎增殖的影响,在此基础上进行了原球茎快速分化的研究。实验结果表明,秋花独蒜兰原球茎的快速增殖培养基为:花宝0.3%+糖2%+BA0.5 mg/L;而液体→固体培养基形式的分化培养比固体→固体培养基形式的分化速度快,且分化的芽的粗壮程度高于固体→固体培养基形式中的芽。
