Seed quality of some species of the genus Musa at the Peter the Great Botanical Gardens

Abstract

Banana genus Musa L. (Musaceae) in the collections of the Peter the Great Botanical Garden BIN RAS is grown 7 species and four cultivars of the genus (all from Musa acuminata).The very first grown one is Musa acuminata (Musaceae), this species has been grown in the Peter the Great Botanical Garden of the BIN RAS since 1932. The original seeds were obtained from the Botanical Garden of Hamburg (Germany). The plants were preserved during the Second World War. Plants bear fruit almost every year. Seeds in fruits are tied and ripen. Laboratory germination of freshly harvested seeds is 64-73%.Musa huangbaoia has been in the collection of the Peter the Great Botanical Garden since 2016. It does not bear fruit regularly. Some individuals behave like monocarpics; after fruiting they die off without forming lateral buds.Freshly harvested Musa mannii seeds begin to germinate in Petri dishes at 15-20 days. Germination is not friendly, stretched. Laboratory germination reaches 15-20%.The position that banana seeds quickly lose their germination capacity has been confirmed. The presence of fruit-bearing species of the genus Musa allows them to be included in the "Index seminum".
