Comparison of Anatomical Structures of Overwintering Branches and Analysis on Cold Resistance of Ribes
[Objective]The wild species and cultivars of Ribes nigrum L.were used as samples to explore the death mechanism and technical measures to solve the death.[Method]The perennial of branch anatomy were used of R.diacantha Pall,R.komarovii var.komarovii,R.odoratum H.L.Wendl.,R.mandshuricum(Maxim.)Kom.,R.nigrum'Ben Lomand'.[Result]MOTIC BA400 micrography showed that the cells of wild species were small and well arranged.The cultivated varieties of the uncoered branch vessel cells was broke down and formed channels directly connected with the outside overwintering in the middle of March,the branches was resulting in irreversible water loss and death.[Conclusion]It would provide theoretical basis for the safe overwintering and cultivation technology of R.nigrum L.
