how does a gumamela plant reproduce if they form seeds but not fruits?

Question

i can't understand how a gumamela plant reproduce, they can be fertilized because they have both male and female organs but they don't form fruits. so how will they get there seed to grow and form a new plant if they don't even produce fruits???

Answer 1

Because the plants have been bred for so many generations in the last 100 years they vary in ploidy, their number of chromosomes. They also result from many species being crossed. This means there are many that are not fertile together. Even the direction matters. Who donates the pollen and who receives it. Today breeders always note the pollen & seed parent of a new cross. For example the chances of success when crossing a H. lilliflorus onto a H. rosa-sinensis is far greater than the reverse cross. This means some varieties are regarded as being “hot pollen” producers and some make reliable female parents. All new cultivars are created from hand pollination so the pollen can be tracked accurately. Breeders dedicate a great deal of time and effort in bringing hundreds of seedlings to flower so they can be assessed for rare individual of superior quality.

Several species are genetically compatible with all forms of H. rosa-sinensis and with each other so are probably all part of the unrecorded genetic history of our modern hibiscus
[H. schizopetalus from the East African coast, H. liliiflorus from Mauritius, H. cameronii from Madagascar, H. fragilis and H. boryanus from Reunion Island, H. arnottianus and H. Kokio from Hawaii, H. storkii from Fiji, and H. denisonii - origin unknown - (possibly synonymous with H. storkii.)]

Hibiscus fruit is an inconspicuous oval capsule of less than 1/2 inch that contains the small seeds. The capsule is a dehiscent fruit composed of five united carpels. Dehiscence means it opens to spill the seeds when it is mature.

Fruit can be either dry or fleshy. Obvious fleshy fruit include the usual dessert mangos & plums but also the starchier cucumber & tomato. Dry fruit include rose achenes found inside the hip, maple tree winged samaras and one-seeded dry fruits of the grains, such as wheat and corn.

Answer 2

fruits are just the juicy flesh around a seed or whatever else contains the seed(s). seeds are what's necessary to reproduce. most gumamela don't produce seeds or fruits because they are highly cultivated to be ornamental, not functional. instead, they are reproduced with cuttings from the plant that root and form new plants. a lot of ornamental plants are reproduced this way and have flowers that don't look like the original natural plant and don't function for reproduction.
