Dissotis, Pinklady Heterotis rotundifolia
Thus, most Melastomataceae species are visited by pollen-gathering bees that use buzz-pollination to expel the pollen through the anther pores. Plants should be evaluated daily for ripened or aborted fruit.
The stems are woody on lower parts of the plant and become hirsutemeaning hairy, towards the top of the plant. Once ripe fruit has been obtained, rotundifola seed should be germinated and the germination percentage should be recorded.
The seeds should germinate in approximately two weeks. However, if pollinations are made in the field, bagging should be done as a precaution against accidental pollination by insects. Catalogue of the Seed Plants of the West Indies.
Space JC; Flynn T, a. Control of the growth and spreading of rotundjfolia plants is much easier in a greenhouse, also. Shawl was a cute little border around a banyan tree.
The characteristic anther appendages probably function as a hold for the bee’s legs Woodgyer, Wiley series in probability and mathematical statistics. Leaves ovate to ovate-lanceolate or suborbicular, 1.
The petals of the flower are 1. A Global Compendium of Weeds. When the stems trail, they root where the leaf connects to the stem, called the “node”. The branches tend to spread wide, and range from pink to a dark reddish in color. Invasive Rotunndifolia and Animals, Biosecurity Queensland.
Heterotis rotundifolia (pink lady)
While the bee sonificates the feeding anthers, it also sonificates the pollination anthers, causing pollen to dehisce from both sets of anthers. Distribution Top of page H. The chromosome number reported for H. The tuning fork is struck upon a hard surface and held to the stamens; a container is needed to catch the pollen as it exits the anthers. 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.
Datasheet Heterotis rotundifolia pink lady.
Institutional sponsor is Dr. Report to the Republic of Palau: Once established, this species completely out-competes vegetation communities by displacing native species and changing community structures PIER, Taxonomic Tree Top of page Domain: Reciprocal crosses should be made between plants in each population if possible Fehr et al.
Figure 8 Mature Dissotis rotundifolia fruits, with ruler gotundifolia show size of fruit. Cook Islands Biodiversity Database. The standard technique is to touch the pollination wand to the pedicel of the flower late in the morning; it is a very effective way of causing pollen to dehisce from the anthers of the flower Rotundifloia et al. Post a comment about this plant. The number of applications will vary from one to three, depending on the interspecific cross; each application must be separated by three days Jones et al.
It has been a very rewarding patio plant and rotindifolia in size at least five-fold since I got it. Distribution Maps Top of page You can pan and zoom the map.
Treatment of diploid and triploid roses with oryzalin, an herbicide that acts as a mitotic spindle inhibiter, was shown to induce polyploidy, and led to an increase in pollen viability, increasing the fertility of the species Kermani et al.
The trailing habit dissotis this species lends itself well to use in a hanging basket Ruter, personal communication, Report to the Government of Samoa on invasive plant species of environmental concern. The genus Dissotis contains species, all native to Africa; D. A survey of reproductive biology in neotropical Melastomataceae and Memecylaceae. Don’t need the entire report? The feeding anthers are shorter than the pollination anthers and are yellow, a color which attracts bees.
More information about modern web browsers can be found at http: Once the optimum dosage of oryzalin to induce polyploidy in the progeny of each cross is determined, this dosage may be applied to all future progeny.
However, in breeding D. At least twenty seedlings of the progeny of each cross should be used for each treatment, as the treatment will not induce polyploidy in each seedling, and the greater number of seedlings that are used, the better the chances of inducing polyploidy are. Oryzalin-induced chromosome doubling in Rosa and its effect on plant morphology dissotid pollen viability.
