耐低温大豆品种系的筛选与研究

耐低温大豆品种（系）的筛选与研究盖志佳1，2　张敬涛1，2　刘婧琦2　蔡丽君2　杜佳兴2　陈　磊1（1黑龙江省农业科学院博士后科研工作站，哈尔滨 150086；2黑龙江省农业科学院佳木斯分院，佳木斯154007）摘要：耐低温大豆品种的筛选不但有利于低温年大豆生产，提高大豆抗冷性，确保大豆稳产，而且有利于大豆免耕技术的推广。

选用11个大豆品种（系）进行萌发期耐低温（6℃）筛选研究，筛选出耐冷型大豆品种2个，分别为金源55与合农60；敏感型品种1个，为黑农48；中抗型品种（系）8个。

试验结果表明，在6℃低温条件下，随着发芽时间的延长，不同品种（系）相对发芽率呈逐渐上升的趋势，低温胁迫下大豆发芽的最佳调查时间为低温处理14d；大豆抗冷性与百粒重呈显著负相关，与蛋白质含量、脂肪含量相关性不显著。

关键词：大豆；低温；筛选；抗冷性；相对发芽率大豆耐冷凉，是黑龙江省重要的油料作物，是植物油和植物蛋白来源最为丰富的作物。

黑龙江省为大陆性季风气候，春秋两季气温变化较大，农作物的生长容易发生冷害。

大豆冷害减产原因可分为3个类型：延迟型冷害、障碍型冷害和生育不良型冷害[1]。

根据大豆对低温的反应将栽培大豆分为耐冷型、中抗型和敏感型[2]。

大豆耐低温萌发是一个复杂过程，其萌发特性前人已进行了有益探索[3-7]，但是关于耐低温大豆品种的筛选试验研究较少。

如何为寒地大豆生产筛选出适宜的耐低温大豆品种是亟待解决的问题。

本试验旨在筛选低温胁迫下发芽速基金项目：黑龙江省农业科学院院级科研项目（2017S07）；农业部东北地区作物栽培科学观测实验站开放课题（2017-3）通信作者：张敬涛率快、发芽率高的大豆品种，研究结果可为育种家育种提供抗冷性强的亲本资源，以及为黑龙江省大豆生产选种提供参考依据，大面积推广应用耐低温品种可有效降低低温冷害对大豆产量的影响，有利于黑龙江省冷凉区大豆生产与发展。

有进化上的重要性，因为它们是保守的，特别是那些亲核性的基团，如巯基（－S~)和氨基（－Ｎ~2)，使其获得抗生素特性。其三，黑色素光吸收和光衍射的特性，被利用在光受体的屏蔽上并且被认为对爬行动物体温调节起到一定的作用。据报道鱿鱼墨黑色素具有体外清除自由基螯合金属离子的特性[９］,鱿鱼墨黑色素还可以保护动物的血清和肝脏中的ＳOＤ和CＳＨ-PX 活性,使动物血清和肝脏中的MＡD和脑脂褐质含量显著降低,起到防止自由基对集体脂质的氧化和对细胞膜的破坏，从而抑制D－半乳糖所致的衰老，有效地清除体内堆积的自由基，使体内自由基防护体系的功能得以恢复[10]。同时鱿鱼墨黑色素对皮肤细胞的生长和代谢具有一定的促进作用，胸腺是T淋巴细胞分化成熟的中枢免疫器官,而在衰老中胸腺衰老较早,T细胞增殖更新减慢，数量下降，免疫功能降低[11]。鱿鱼墨黑色素能有效防止免疫器官的萎缩，达到延缓衰老的目的[1２]。

三、安装：
本设备应当在下列环境中使用： 1、环境温度：10～30℃，相对湿度85%以下； 2、无强烈光照、无强烈腐蚀性气体，通风良好； 3、电源：～220V±10%，50Hz，容量不小于 2KW，必须是符合标准的带接地的单相三线制 10A 插座，接地必须符合标准要求。如图 1：
四、使用方法
1、通电
3、时钟校准方法
本仪器出厂时已对时间进行校准，您也可以对本培养箱进行进一步的调整。
调整方法：按
（此时“时钟”数码块闪烁），请按数字键输入时间，
如时间为 13:20，即：请依次输入
请再按
完成。
