    Opis:
    The interaction between foliar treatment with 100 mg∙dm–3 of both gibberellic acid 4+7 (GA4+7) and benzyladenine (BA) and vase solution containing 3% sucrose was analysed in cut Lilium ‘Alma Ata’. GA4+7+BA considerably delayed leaf senescence, suppressed anthocyanin accumulation in the leaves of plants held in the sucrose solution and improved the average longevity of the flowers and the vase life of the stems. Sucrose in the vase solution strongly reduced the abscission of leaves and contributed to the enlargement of the top flower. The number of significant interactions between the treatments indicated that the investigated factors acted dependently mainly on flower quality, while their action on leaf quality was mostly independent. Results show that combined treatment with growth regulators and sucrose may considerably increase postharvest quality of cut Lilium ‘Alma Ata’.

    Opis:
    Silybum marianum (milk thistle) is among the top selling herbal products in the U.S., in Italy and in other countries. Despite its economic importance as an officinal and medicinal species, only few improved genotypes exist and the species is still marked by traits that are typical of non-domesticated plants. Based on this evidence, further genetic improvement is required for the complete exploitation of milk thistle as a crop species. The first step in order to allow further breeding programmes of the species is the setup of a reliable crossing protocol. The present paper, after a brief review of S. marianum flower anatomy, describes a crossing method for this plant. The correct phenological stage for emasculation is BBCH growth stage 54. If manual pollination is repeated two days after emasculation, a significant increase of F1 fruits can be obtained. By utilizing the proposed protocol, an average 70–90 florets per flower head are emasculated and percentage of success (F1 fruits harvested) usually ranges between 27 and 70%. The proposed crossing protocol will constitute an important tool in order to allow the further genetic improvement of this species.

    Opis:
    This study focused on examining the effect of vegetables extract foliar application on storage quality of the grapes grape (Vitis vinifera L. cvs. ‘Perlette’ and ‘King’s Ruby’). The vines were sprayed after fruit set twice at 15 days interval at concentrations of 0, 0.20%, 0.30% and 0.40%. Fruit were harvested and kept under cold-storage at 0.5 ±0.5°C and 90% RH for 28 days. The physicochemical properties of treated and untreated berries were analyzed at 7 days intervals during the cold storage. The results showed that the pre-harvest application of vegetable extracts reduced the weight loss and inhibited the fruit decay. Treated grape also had higher ascorbic acid contents, total phenolics, 2,2-diphenyl-1-picrylhydrazyl-radical (DPPH) scavenging activity, and higher soluble solid contents, titratable acidity, and reduced sugar:acid ratio. The concentration of 0.30% and cultivar ‘Kings Ruby’ gave the best result as compared to untreated control. In conclusion, pre-harvest vegetables extract application on berries showed higher antioxidant activities in grape berries, and maintained their post-harvest quality. These results indicated that foliar spray of vegetables extract could effectively improve the fruit quality, mainly through the reduction of phenolic content.
