Floral biology of tree fruit rootstocks

Effects of in vivo mycorrhization on micropropagated fruit tree rootstocks

In order to establish an endomycorrhizal symbiosis on micropropagated plants and to evaluate its effect on plant growth and survival, three rootstocks belonging to the Prunus genus were used: M51 (P. dulcis), GF677 (P. persica×P. dulcis) and cv Citation (P. domestica×P. persica). The plants were micropropagated and in vitro rooted. Spores of Glomus mosseae (LMSS) and Scutellospora calospora (SC...

Floral Biology: Implications for Fruit Characteristics and Yield

Field Performance of Grafted Fruit-Tree Rootstocks Was Not Affected by Micropropagation

The use of micropropagated trees has been widely extended, since micropropagation is a convenient technique of vegetative propagation that shows a number of interesting advantages, mainly for woody fruit trees. However, only few studies can be found in the literature on the field performance of micropropagated trees. In this work, the performance of different micropropagated fruit-tree rootstoc...

The complex jujube genome provides insights into fruit tree biology

The jujube (Ziziphus jujuba Mill.), a member of family Rhamnaceae, is a major dry fruit and a traditional herbal medicine for more than one billion people. Here we present a high-quality sequence for the complex jujube genome, the first genome sequence of Rhamnaceae, using an integrated strategy. The final assembly spans 437.65 Mb (98.6% of the estimated) with 321.45 Mb anchored to the 12 pseud...

Floral biology of hybrid zones

Hybridization between closely related species is relatively common in angiosperms and can create a natural hybrid zone. We review recent experimental studies of floral biology in pairs of hybridizing species, emphasizing comparisons of the floral morphology and nectar rewards of hybrid plants with that of their progenitors, and quantifying the influence of these floral traits on pollinator beha...
