摘要
为正确选择和利用苹果砧木,促进苹果经济栽培获得成功,从砧木和接穗的亲和力研究、砧木对接穗生理效应的影响、砧木对树体生长结果的影响3个方面综述了苹果砧木对嫁接品种影响的研究现状。砧木和接穗嫁接亲和性的研究多集中在嫁接后接口愈合情况、愈合时间以及嫁接体成活生长情况等方面,目前从形态学和解剖学方面研究的更为深入,在基因、转录和蛋白组学水平上也有涉猎,但还不够深入。砧木通过影响嫁接品种超氧化物歧化酶、过氧化氢酶、过氧化物酶、生长素氧化酶等酶的活性,从而影响其一系列生理活动,影响内源激素的代谢水平,矿质元素的吸收和运输,以及嫁接品种光合能力等,进而影响嫁接品种的生长发育。目前对这种影响机制还不十分明确,今后应加强此方面的研究,尤其是不同砧木对嫁接品种生理生化物质的产生、状态、运转及降解规律影响等方面的研究,同时还应加强砧穗互作效应的研究,以帮助选择不同生态区的适宜砧穗组合,促进苹果产业健康发展。
In this paper,current research advances of the rootstock-scion affinity,physiological effects and fruiting patterns were reviewed for properly selecting apple rootstocks to cultivate apple successfully.,and the rootstock-scion affinity are mainly focus on healing condition,healing time and development of grafts.Currently,many researches were carried out on the morphological and anatomical level,while less on the transcriptional and protien levels.The main influence factors of growth and development of grafting varieties are POD,CAT,POD,IOD and other enzymes which affect the physiological activities,metabolism level,absorption and transportation of mineral elements,and photosynthetic capacity.In the future,it is necessary to further study on the mechanism of rootstocks effects on growth and development of grafted varieties,especially effect on the production,state,transporting,degradation regulation of biomatters.Moreover,interactions between rootstock and scion should be further studied to help choose proper combination of rootstock and scion and to accelerate development of apple industry.
