本文主要研究内容
作者孙梦璟（2019）在《蓝靛果花粉寿命及授粉亲和性的研究》一文中研究指出：蓝靛果作为新兴小浆果树种在东北地区广泛分布,蓝靛果的果实中含有非常丰富的生物活性物质,具有较高的保健及药用价值,越来越受到人们的关注。但由于其野生资源分布分散、采摘困难及果实的变异大等特点,远远不能满足消费者的需求。因此,目前大量进行人工栽培,但对授粉亲和性方面的相关研究较少。本论文为了解决生产中因盲目栽植而导致的座果率低,产量低等问题,以长白山野生蓝靛果优良单株为试材,探讨了蓝靛果花粉萌发的培养基配方、授粉习性、自交亲和性及不同优良单株间的开放授粉亲和性,为其进一步推广应用及进一步选育新品种提供理论依据,研究结果如下:1、蓝靛果优良单株花粉萌发的最佳培养基配方为:27.5%蔗糖+100 ppm硼酸,调pH值为6.0,蓝靛果优良单株L1,L2及L3在这个培养基上的花粉萌发率(以萌发出单个花粉管的数量为主)分别为53.4%、50.9%、51.6%;2、在不适宜的培养基下,蓝靛果的花粉可萌发出多个花粉管,萌发出多个花粉管的数量在3个优良单株间差异不显著,都介于1～4个之间,其中,萌发出三个花粉管的最多,占萌发花粉的58.8～61.4%,但这些花粉管长度都短于花粉粒直径,不能进一步伸长;3、不同的贮藏环境对蓝靛果花粉的寿命影响较大,蓝靛果花粉在室温下只能保持一周左右的生活力,在冰箱冷藏层为一个月左右,在冰箱冷冻层中贮藏,并且中间不取出来的前提下储藏一年仍可保持与贮藏初期无显著差异的萌发率;4、在进行蓝靛果异地杂交育种时,如果母本花先开,可将父本花粉贮藏于冰箱的冷冻层,用于第二年的杂交。采集蓝靛果花粉时应选择晴朗的天气,上午采集并剥离花药后当天把散出的花粉收集,并放入冰箱冷冻层保存,以便提高其花粉萌发率;5、三个蓝靛果优良单株都属虫媒传粉,L1自交不亲和,L2自交结实率为100%,L3自交结实率为85%,三个单株混种时的开放授粉坐果率分别为94%、96%及98%。因此,L1在生产上应配置授粉树或多品种混种,以提高产量,而L2和L3理论上不需要配备授粉树,但自交和异交的果实在品质上有无差异有待于进一步研究。
