brad16 says... Hi Doc, I'm going to guess that you're interested in the Riberry mainly as a hedge (being in Ryde I don't think you're after a big tree), but would also like a bowl of fruit ... because ... why not eh? I agree that Daleys pollination recommendations are not exactly helpfull. It doesn't indicate whether 2 trees of the same species are required, or if the tree requires another species as a 'cross-pollinator', and this leaves a lot of people wondering about the 'compatible plant' bit. It means 'do your own research' if the recommendation isn't '1 (Self Pollinating)'. Googling pollination for a species of plants usually doesn't help the average person because most of the results are academic research papers, and they focus on other things that impact pollination efficiencies, like environmental factors and hybridisation. Here is a link to the Rural Industries Research And Development Corporation publication, titled 'Understanding the Cropping Behaviour of Riberry'. https://rirdc.infoservices.com.au/downloads/10-194 Lots of reading to answer such a simple question, but the gist, that concerns this question, is: * Riberry has not been thoroughly researched, but a general understanding is that cross-pollinating (with other species) should improve the number fruit. * Cross pollination will increase the number of fruit seeds, where a higher proportion of fruit without seeds may be possible without pollination (but more likely less fruit). * 'Glover's Seedless' variety produces predominately seedless fruit in a 'clonal' orchard. (Note: this means no pollen from non-'Glover's Seedless' tree, which would be near impossible to regulate in a suburban yard, such as Ryde). This is interesting though because it does indicate that Riberry does not necessarily require another variety to set fruit. If you did want to cross-pollinate, look for another Syzygium. There are loads for sale, at Daleys, or most other nurseries. | About the Author brad16 GOROKAN,2263,NSW 1st December 2016 12:13pm #UserID: 14079 Posts: 175 View All brad16's Edible Fruit Trees |

jakfruit etiquette says... Plants reproduce sexually like other lifeforms (and some plants reproduce asexually).In some species the male and female parts are in the same flower, on the same plant. In others, the male and female parts are on seperate flowers on the same plant. In other species, the male flowers are on male plants and the female flowers are on female plants. Then you can mix this around to get various combinations of systems in some species. Some plant species can self fertilize, and some have methods to prevent this or promote outcrossing to other plants of the same species. Compatible plants will have corresponding flowers to match the breeding system used by the plant species, including timing of pollen release and ovule ripening time. Generally compatible plants are going to be in the same species, or a close relative in the same Genus. Wide crosses in nature, (ie island flora), or tricks used by plant breeders can proove the exception. As you mentioned Riberries, they are a Syzygium species, and some hybrids with other Syzygium species are available. ie Cascade S.leuhmanii X S. wilsonii. | About the Author jakfruit etiquette vic 1st December 2016 9:29pm #UserID: 5133 Posts: 915 View All jakfruit etiquette's Edible Fruit Trees |
