Ovule positions within linear fruit are correlated with nonrandom mating in Robinia pseudoacacia

Post-pollination processes can lead to nonrandom mating among compatible pollen donors. Moreover, morphological patterns of ovule development within linear fruits are reportedly nonrandom and depend on ovule position. However, little is known about the relationship between nonrandom mating and ovule position within linear fruit. Here, we combined controlled pollen competition experiments and pa...

Chromatographic Analysis of the Flavonoids from Robinia Pseudoacacia Species

THE PURPOSE OF THIS STUDY WAS THE QUALITATIVE AND QUANTITATIVE ANALYSIS OF FLAVONOIDS FROM ROBINIA PSEUDOACACIA USING TWO DIFFERENT TECHNIQUES OF ANALYSIS: Thin Layer Chromatography (TLC) and TLC coupled with photo-densitometry. The results obtained by chromatographic analysis showed a higher concentration of flavonoids in flowers than in leaves. The flowers harvested in the plains have a highe...

Genetic transformation of Robinia pseudoacacia by Agrobacterium tumefaciens.

Transgenic Robinia pseudoacacia plants were obtained by Agrobacterium tumefaciens mediated gene transfer. Agrobacterium strain LBA4404 harbouring a binary vector that contained the chimeric neomycin phosphotransferase II (NPTII) and beta-glucuronidase (GUS) genes was co-cultivated with hypocotyl segments of in vitro raised seedlings of Robinia. Parameters important for high efficiency regenerat...

Diversification Factors of Cultivators/Investors of Robinia pseudoacacia (Black locust)

In an effort to minimize environmental degradation caused by the intensive use of agrochemicals, European Union adopted regulations relevant to afforestation and set aside of agricultural land. The multifunctional role of agriculture enhanced through these regulations and provided adequate motives for a change in the conventional land uses. Cultivators/investors that are interested in afforeste...
