Response to In Vitro Micropropagation of Plants with Different Degrees of Variegation of the Commercial cv. Fancy (Cactaceae).

This study aims to establish efficient in vitro propagation protocols for cv. Fancy, an ornamental cactus with variegated variants, by evaluating the effects of cytokinin type and explant source on the organogenic response. Plants with different degrees of variegation (0-100%) were classified by size to obtain different explant types (apices, central discs, epicotyls, and hypocotyls).

Micropropagation and Acclimatization of cv. Fancy (Cactaceae): Developmental Responses to Different Explant Types and Hormone Conditions.

The genus includes numerous highly valued species in the ornamental plant market and their propagation is usually carried out using traditional methods. However, there is a lack of information regarding the efficiency of micropropagation through in vitro tissue culture techniques on these species. So, with the objective of establishing an efficient micropropagation protocol that allows for optimizing the plant obtaining processes, the morphogenic potential of cv.

The role of traditional varieties of tomato as sources of functional compounds.

Background: Traditional varieties of tomato, usually associated with excellent organoleptic quality, are increasingly appreciated in European quality markets. A collection of 126 populations of 16 traditional varieties from the east of Spain (a secondary diversity center for tomato) have been evaluated over 2 years in order to determine their potential value as sources of functional compounds, including ascorbic acid, lycopene, β-carotene and total phenolic content.

Results: Population and population × year interaction significantly affected lycopene and ascorbic acid contents, while year effect was also significant for β-carotene.
