Cím:In Vitro Tuberization in Hormone-Free Systems on Solidified Medium and Dormancy of Potato Microtubers / Dobránszki Judit, Magyarné Tábori Katalin, Hudák Ildikó
Megjegyzések:The use of in vitro tubers (microtubers) as the final products of potato micropropagation, in addition to or rather than in vitro plantlets has several advantages in seed tuber production. Moreover, microtubers are important in germplasm storage and they are used as experimental tools in basic research and in in vitro selection of agronomically important characters. Their reliable production has, therefore, been widely studied under different in vitro growing conditions, with varying efficacy regarding the number, size and weight of microtubers. Microtubers exhibit different periods of dormancy depending on the genotype and on the in vitro conditions during tuberization. Generally, the use of growth regulators for tuberization does not allow the maximal expression of the tuberization capacity that is determined by the genotype, and therefore, the production of microtubers in sufficient quantity and size. As a result, there are later problems in breaking tuber dormancy. Although the growth responses between in vitro and field-grown tubers are very similar, there is the possibility for the production of in vitro tubers without using growth regulators by modifying in vitro environmental factors, such as light, temperature and mineral nutrition, among others. This review discusses the results of in vitro potato tuberization performed in hormone-free systems on solidified medium, including the effects of environmental factors, composition of medium, genotype and explants. Furthermore, we assess the effects and post-effects of tuberization conditions on the dormancy and sprouting characteristics of microtubers originating from these hormone-free systems.
