Abstract

To promote the artificial cultivation of Hyssopus cuspidatus Boriss., a characteristic medicinal herb in Xinjiang, and to expand the supply of raw medicinal materials, this study aimed to explore the optimal conditions for its seed germination. Using seeds of H. cuspidatus as experimental materials, their morphological characteristics, purity, moisture content, and thousand-seed weight were measured. The effects of low-temperature treatment time, seed soaking temperature, germination medium, pH, and exogenous chemical concentrations on seed germination were examined separately. The results showed that H. cuspidatus seed length, width, and thickness were (2.26±0.69)mm, (1.21±0.48)mm, and (0.72±0.65)mm, respectively; the thousand-seed weight was (0.47±0.11)g; seed purity was (92.90±0.17)%; and seed moisture content was (5.80±0.69)%. Under different treatments, the germination rates after low-temperature freezing for 5 days, soaking in 40℃ water, double-layer gauze medium, and pH 8 solution were 72.0%, 66.0%, 68.0%, and 68.0%, respectively. Among the exogenous chemical treatments, the highest germination rates after treatment were achieved with 0.2 mg/mL gibberellic acid and 0.2 mg/mL polyethylene glycol, which were 74.0% and 72.0%, respectively. This study identified the optimal conditions for seed germination of H. cuspidatus, providing a scientific basis for its artificial cultivation. This will help promote large-scale planting and alleviate reliance on wild resources.

铁皮石斛无性快繁各阶段对植物激素的需求不同。为探究外源激素配比与铁皮石斛组培苗生长之间的关系,以浙江省天目山的铁皮石斛带节茎段为外植体,进行铁皮石斛丛生芽诱导、增殖和生根试验,比较各试验阶段激素配比对铁皮石斛生长的影响,从而筛选出适合铁皮石斛茎段快繁的最佳激素条件,建立铁皮石斛茎段无性快繁体系。结果表明,丛生芽诱导最佳激素条件为1.0 mg/L NAA+2.0 mg/L 6-BA,发芽率97.8%,芽健壮;丛生芽增殖的最佳激素条件为0.5 mg/L NAA+2.0 mg/L 6-BA,增殖率86.9%,植株长势良好;丛生芽生根阶段的最佳激素条件为1.0 mg/L NAA+1.0 mg/L IBA,生根率为83.4%,根系健壮发达且无黄化现象。研究证实,激素配比与培养基盐浓度协同调控铁皮石斛形态发生,其中7~8叶期为生理响应关键节点。本研究筛选出的激素组合可为兰科药用植物规模化组培提供理论依据与技术参考。

为筛选泡果白刺(Nitraria sphaerocarpa)优质种源进行人工栽培,以河西走廊戈壁荒滩、山前平地、荒漠沙地采集的25份泡果白刺种子为材料,研究其物理特性、休眠特性、休眠破除方法及萌发特性。结果表明:泡果白刺种子呈纺锤形或针形,种皮乳黄、黄褐色,极少数为黑褐色;种子外表皮较软,表面粗糙;种子长7.01~9.29 mm,宽1.90~2.63 mm,形状指数为5.41~11.18,千粒重8.28~19.23 g,比重1.02~1.16 g·cm-3,容重282.17~448.33 kg·L-1,优良度34.5%~92%;初始发芽率4.25%~30.25%。不同样品种子各指标均达到了极显著差异(P<0.01);种子比重与种子优良度极显著正相关(P<0.01),种子优良度与初始发芽率和样地水分极显著正相关(P<0.01)。在果实发育期灌水保育,可有效保证种子优良度;采集的种子中休眠种子和非休眠种子同时存在,不同采种基地种子特征特性和休眠深度不同;种子休眠原因是种子中存在发芽抑制物质,种子中的发芽抑制物能溶于NaOH、Ca(OH)<sub>2</sub>或KOH溶液,且发芽抑制物具有非专一性,既可抑制自身萌发,也可抑制其他植物种子萌发。用NaOH、Ca(OH)<sub>2</sub>或KOH溶液处理后清洗种子,可剔除种子发芽抑制物,使种子休眠完全释放。破除休眠后,25份泡果白刺种子发芽率为13%~90%,平均发芽日数为1.88~2.95 d,发芽指数4.03~34.07。适宜条件下,泡果白刺种子置床后2 h内为急剧吸水期,2~14 h为缓慢吸水期,14 h后为饱和吸水期,吸水率维持在60%;种子萌发过程中物质效率达到67.09%,种子萌发形成的幼苗为双子叶子子叶出土类型幼苗。

以青藏高原东缘地区24种唇形科(Lamiaceae)种子为材料,在室外自然光照条件下进行萌发试验,研究种子大小与萌发特性的关系,为当地的植被保护或恢复对策的制定提供一定的科学依据。结果表明:24种唇形科植物种子的百粒重为0.0061~0.5688 g,跨越2个数量级,平均大小0.1200 g,60%的物种种子百粒重小于0.1200 g,表明在青藏高原东缘唇形科植物种子中小种子占优势。种子大小与萌发率和萌发速率指数呈极显著负相关(P<0.01);种子大小与集中度呈极显著正相关(P<0.001);种子大小与萌发开始时间的相关性不显著。这些结果说明,这24种唇形科植物的大种子物种和小种子物种有2种相反的萌发对策:小种子萌发率高,萌发速率快,萌发历期短,萌发整齐性好;大种子与小种子相反,并共同与其扩散能力构成了一个由小种子物种(拓植能力)到大种子物种(竞争能力)的连续体,从种子萌发对策上解释了大、小种子物种在同一自然群落中如何共存的问题。

The pre-germinative metabolism is among the most fascinating aspects of seed biology. The early seed germination phase, or pre-germination, is characterized by rapid water uptake (imbibition), which directs a series of dynamic biochemical events. Among those are enzyme activation, DNA damage and repair, and use of reserve storage compounds, such as lipids, carbohydrates and proteins. Industrial seedling production and intensive agricultural production systems require seed stocks with high rate of synchronized germination and low dormancy. Consequently, seed dormancy, a quantitative trait related to the activation of the pre-germinative metabolism, is probably the most studied seed trait in model species and crops. Single omics, systems biology, QTLs and GWAS mapping approaches have unveiled a list of molecules and regulatory mechanisms acting at transcriptional, post-transcriptional and post-translational levels. Most of the identified candidate genes encode for regulatory proteins targeting ROS, phytohormone and primary metabolisms, corroborating the data obtained from simple molecular biology approaches. Emerging evidences show that epigenetic regulation plays a crucial role in the regulation of these mentioned processes, constituting a still unexploited strategy to modulate seed traits. The present review will provide an up-date of the current knowledge on seed pre-germinative metabolism, gathering the most relevant results from physiological, genetics, and omics studies conducted in model and crop plants. The effects exerted by the biotic and abiotic stresses and priming are also addressed. The possible implications derived from the modulation of pre-germinative metabolism will be discussed from the point of view of seed quality and technology.

为研究PEG模拟干旱胁迫下玉米萌发指标和生理指标变化,设置20% PEG-6000进行干旱处理,对玉米萌芽期发芽率、发芽势、萌发指数、胚根长及苗期叶绿素值(SPAD)、超氧化物歧化酶(SOD)活性、丙二醛(MDA)含量等指标进行测定,并采用隶属函数法对不同品种的抗旱性进行评价。结果显示,在干旱胁迫条件下,各玉米品种发芽率、发芽势、萌发指数、胚根长较对照均有所下降,叶绿素含量和SOD活性降低,MDA含量增加。利用隶属函数法评价玉米抗旱性,‘新农008’的隶属函数平均值大于0.7,属于强抗旱品种;‘中榆9号’、‘中榆1号’和‘沃玉3号’隶属函数平均值均小于0.4,属于弱抗旱品种。
