    • 摘要: 为探究植物生长调节剂和层积处理对花曲柳种子萌发的影响,以未层积和经过层积处理(4周)后的花曲柳种子为材料,使用不同浓度(10^(-6)、10^(-5)、10^(-3)mol/L)的外源GA_(3)(赤霉素)、6-BA(6-苄氨基嘌呤)、乙烯利和KT(激动素)溶液浸种24 h处理种子,以清水浸种24h为对照,比较经过不同处理后种子的萌发表现。结果表明,层积处理对于提高花曲柳种子的发芽力有明显促进作用,除10^(-3) mol/L的GA_(3)浸种处理可显著提高种子发芽指数和缩短平均发芽时间外,其他不同浓度和不同种类的植物生长调节剂浸种处理对于提高种子发芽力均无明显效果,因此播种前采用植物生长调节剂浸种对于提高花曲柳种子的萌发能力作用不大,低温层积处理促进种子萌发效果明显。

    • 摘要: 为了提高钟花樱桃(Cerasus campanulata)的繁殖系数,满足市场对其优质种苗数量和质量的要求,以钟花樱桃种子、枝条为材料,通过层积处理、插条选择、激素处理、嫁接时间与方法的比较等探讨了相关因素对钟花樱桃种子发芽、插条生根、嫁接愈合成苗的影响.结果表明细河砂和蛭石层积处理种子发芽率较高;9月中旬不适合采用硬枝扦插,生长调节剂可促进嫩枝生根;钟花樱桃在生长季嫁接最适合是腹接法,应尽量采用同属植物作为砧木.

    • 摘要: The dormancy of Heracleum moellendorffii Hance seeds caused many problems on agricultural production,such as lower germination rate,irregular seedling and long period of grow seedlings,etc.In order to solve these problems in production,four kinds of variable temperature stratifications were designed.The embryo development was observed,the morphology,physiological and biochemical indices of seeds were measured by periodic sampling.Futhermore,the dynamic changes of these indices and their relationship with after-ripening of seeds were analyzed.The results showed that the embryo of Heracleum moellendorffii Hance seeds gradually developed from heartshape embryo in late stage to torpedo-shaped embryo and finally formed the cotyledon embryo by the variable temperature stratification,which indicated the achievement of morphological after-ripening.In the process of variable temperature stratification,the duration of low temperature at 4 °C had the greatest influence on the development of embryo,and the longer the time was,the better the seed embryo development was.Compared with the four kinds of variable temperature stratification,the pattern of the third stratification (20 °C,10 d→4 °C,90 d→20 °C,5 d)was most conducive to the development of Heracleum moellendorffii Hance seed embryos,the length and the rate of embryo increased fastly.The seed embryos entered cotyledon stage firstly under the third pattern which was a cost-effective seed treatment method.In the growth process of Heracleum moellendorffii Hance seed embryos accompanied by changes in nutrients.Although the specific process of nutrient changes in different variable temperature stratifications were different,the overall trend was basically identicial.The content of soluble sugar changed from decreasing to increasing and then declined,while the content of soluble protein,starch and crude fat decreased in general.This study provided a theoretical basis and technical support for revealing the dormancy mechanism of Heracleum moellendorffii Hance seeds,breaking the dormancy of seeds,developing its production in agriculture and adjusting the economic structure of forest area.%针对老山芹种子休眠特性及其生产上存在的种子发芽率低、出苗不整齐及育苗周期长等问题,设计四种变温层积处理,定期取样,观察种胚发育情况,测定种子影态及生理生化指标,分析两类指标动态变化规律及与种子后熟关系.结果表明,经变温层积处理后老山芹种胚逐渐生长发育,由心形胚后期经鱼雷形胚后进入子叶期胚时期,完成形态后熟.变温层积过程中4°C低温阶段持续时间对种胚发育进程影响最大,时间越长越利于种胚发育.四种变温层积处理相比较,处理三模式(20°C,10 d→4°C,90 d→ 20°C,5d)更利于老山芹种胚形态后熟完成,胚长和胚率增长最快,最早进入子叶期胚,是有效的种子处理方法.老山芹种胚发育过程伴随营养物质变化,不同变温层积处理营养物质变化具体过程不同,但总体趋势基本一致,其中可溶性糖含量表现为先降后升再降趋势,可溶性蛋白质、淀粉和粗脂肪含量总体呈下降趋势.研究为揭示老山芹种子休眠机理、打破种子体眠、发展老山芹产业、调整林区经济结构提供理论依据和技术支撑.

    • 摘要: Some different effects on the seed germination of Hypericum longistylum, basing on the study of temperature,light, acid, alkali, and salt by comparative experiment. It also provides a theoretical basis for its artificial propagation. The research shows that:Light can promote the seeds germination. The effects of different temperature treatments on seed germination of Hypericum longistylum were significant, and the germination rate was the highest at 20°C. The germination rate increased significantly at 25 mmol/L Na2 CO3 and pH 5. 0,pH 5. 4 and low temperature stratification treatment. The germination rate was normal under salt stress,but it decreases with the increase of salt concentration;The germination rate was promoted under the condition of alkali stress,and it increased first and then decreased with the increase of alkali concentration,the germination rate was 74% at 10 mmol/L Na2 CO3;Under the condition of acid stress,germination could occur normally,and the germination rate gradually increased with the decrease of pH,the germination rate reached 72% at pH 4. 6.%通过对比试验,研究温度,光照,酸、碱、盐胁迫等不同处理对长柱金丝桃种子萌发的影响.结果表明:光照可以促进种子萌发;不同温度处理对长柱金丝桃种子萌发影响显著,20°C下发芽率最高;浓度25 mmol/L的Na2 CO3处理和pH为5.0,5.4的低温层积处理可明显提高种子发芽率;盐胁迫下种子能够萌发,但发芽率随盐浓度的提高而降低;碱胁迫下可以促进种子萌发,发芽率随着碱浓度的增大呈先升高后降低的趋势,浓度10 mmol/L Na2 CO3下发芽率最高达74%;酸胁迫下能够萌发,发芽率随pH的降低逐渐升高,在pH为4.6下发芽率达到72%.

    • 摘要: 为了确定枫杨种子的休眠原因及其打破休眠的方法,以枫杨成熟种子为材料,对种子透水性、种子浸提物的生物抑制作用、种子催芽处理效果以及种子在不同温度下的萌发能力进行研究.结果表明:枫杨种子种皮透水性良好,种子浸提液中存在发芽抑制物质,抑制物质的存在是造成种子休眠的主要原因.直接埋藏和混雪后埋藏解除枫杨种子休眠的效果不理想;低温层积解除种子休眠效果较好,层积时间达到120d时种子萌发率可以达到89%.温度显著影响枫杨种子的萌发,25°C的恒温条件下种子萌发能力显著高于其它温度条件.结论:枫杨种子不存在物理休眠,属于生理休眠类型,种子需要低温层积处理120d打破休眠,解除休眠种子的适宜萌发温度是25°C.%In order to determine the cause of seed dormancy and the method for breaking dormancy, the Pterocarya stenoptera seeds were used to study the seed permeability, the biological inhibition of seed extract, the effect of seed germination and the seed germination at different temperatures. The results showed that the water permeability of seed coat in Pterocarya stenophylla was good. There was germination inhibiting substances in the extract of Pterocarya stenoptera seeds, and the inhibitory substances may be the main cause of seed dormancy. Outdoor overwinter burying and outdoor stratification with snow had no obvious effect on dormancy breaking. Indoor cold stratification to remove seed dormancy was better. When cold stratification time reached 120 days, the germination rate was 89%. The temperature significantly affected the seed germination, and the germination ability under 25 °C was better than other temperature regimes. In conclusion, the Pterocarya stenoptera seed was not physical dormancy but physiological dormancy, and 120 days cold stratification was needed to break seed dormancy. The best germination temperature for dormancy released seeds was 25°C.

    • 摘要: 研究了不同层积处理对薄壳山核桃种子发芽的调控效应.研究发现,不同基质配比处理种子萌动率均高于对照,表现为基质4>基质2>基质1>基质3,种子萌动率分别为44.8%、41.2%、40.5%、35.9%,对照河沙处理种子萌动率最低,仅为32.5%.不同层积时间对薄壳山核桃种子萌动的影响存在差异,层积30 d,种子没有萌动的迹象;层积60 d,种子有8.3%开始萌动;层积90 d,种子有30.8%开始萌动;层积120 d萌动种子达45.2%.层积30 d处理,播种后发芽速度最慢,播种后20 d未见发芽,播种后40 d发芽率只达到10.2%,烂种率最高,达46.2%,播种后60 d,好种率仍为24.8%,说明层积时间不足,以致播种后部分好种子未能发芽;层积120 d处理,发芽速度最快,播种后20 d发芽率38.2%,40 d发芽率达到53.9%,好种率为0.播种后0~20 d,薄壳山核桃种子内的可溶性糖含量缓慢下降,之后可溶性糖含量急剧下降直至播种后40 d,播种后50~60 d,可溶性糖含量下降缓慢.可溶性蛋白含量从播种开始到播种后20 d下降缓慢,播种后20~40 d,可溶性蛋白含量下降幅度最大,播种后50 d可溶性糖含量逐渐上升.淀粉含量播种后0~10 d缓慢下降,播种后10~40 d淀粉含量下降幅度较大,播种后50 d,淀粉含量的下降速度变缓.研究表明,泥炭:蛭石:珍珠岩=1:1:1的基质配比在质量、吸湿性和透气性上具有优势,是较为理想的层积基质.层积120 d处理,种子萌动率最高,发芽速度最快.
