Once viable seed has been obtained and germinated, the progeny should be grown out and phenotyped.
Views Read Edit View history. In interspecific crosses, it is possible that germination will not occur due to incompatibility between the endosperm and the embryo of the seed Ng et al. Dicotyledonae Summary of Invasiveness H. Once viable seed is obtained, it is sown on top of slightly acidic potting media and maintained under mist until germination. Renner reported that Melastomaceae flowers are herkogamous, which means that their stamens and pistils are of different lengths.
Space JC; Flynn T, a. It has been a very rewarding patio plant and increased in size at least five-fold since I got it. There are at least five other names for it.
Reproductive Biology In H. The species is resistant to drought and very easy to propagate vegetatively Ruter, personal communication, ; personal observation.
Factsheet – Dissotis rotundifolia
Renner, Figure 4. Personal tools Log in. If the crosses to be rotundifolua are interspecific crosses, each population of the other Dissotis species to be crossed with D. It covers grass, it covers flower beds, it doesn’t stop. I have mine grwoing on northside of home in shady side yard as a border, among autumn ferns. Once the seeds have germinated and have at least two true leaves, they may be transferred into individual pots.
The chromosome number reported for H.
In the Melastomaceae the style is often longer than the stamen. The wands are readily available from greenhouse supply companies and require only a supply of batteries to keep them operational. Growth habits also differ between Dissotis species, varying from creeping in D. Different populations of Dissotis rotundifolia should be clearly labeled in order to minimize errors when crossing.
Pollination is done by hand, using a tuning fork to cause pollen to dehisce and collecting the pollen in a vessel for use in pollinations. Post a comment about this plant. History of Introduction and Spread Top of page H. More than one replicate of each species is desirable Dowdy et al, In the sun it performs less vigorously, best with some shade and lots of water. Mapping of quantitative trait loci involved in ornamental traits in Alstroemeria.
Figure 5 Roots at node of Dissotis rotundifolia. Figure 1 Dissotis rotundifolia flower and immature fruits.
Different pollination techniques have been used with crops with poricidal anthers, such as solanaceous crops. Plants produce large amounts of seeds, but the species also spreads vegetatively by stem fragments PIER, Contact Submit an Article Advertise.
Habitat Top of page H. Eating the edible, purple-blue berries will stain the mouth black. Osbeckia rubropilosa De Wild. Once the progeny is phenotyped, the best of the progeny for ornamental use are used in further crosses, or propagated vegetatively to increase the numbers of the new hybrid.
Dissotis rotundifolia – Wikipedia
Don Osbeckia rotundifolia Sm. However, if the end of the anthers touch the stigma as the anthers unfold and the flower is shaken or moved in some way that causes pollen to dehisce, it is possible to get self-pollination.
The main traits of importance in phenotyping the hybrids are size of flowers, length of flowering period, and vigor of growth. A plant growth regulator may be applied to slow the rate of growth and avoid having to periodically prune back the plants.
If pollinations are made in the greenhouse, it is not necessary to bag the pollinated flowers. If you cut it back, it regrows in the same spot. Control of the growth and spreading of the plants is much easier in a greenhouse, also. The rate of fertilization may be gradually increased to ppm after two weeks at 50 ppm.
