Morphological and anatomical observations of abnormal somatic embryos from anther cultures of Citrus reticulata

A morphological and anatomical study of regenerants obtained from mandarin anther culture was carried out. Beside morphologically normal somatic embryos, abnormal structures were originated in the course of somatic embryogenesis. Anatomical anomalies can be found at several growth stages, causing the formation of slender stems, stubby structures, non-functional leaves. When too long, some structures are subject to shedding, with the formation of various abscission zones. Most of them are subject to degeneration, although many are capable of further, localized, morphogenesis. A thorough knowledge of morphology and anatomy of normal and abnormal regenerants could make possible to select and s…

Evaluation of intra-cultivar variability in Olea europaea L. cv. Leccino using morphological, biochemical and molecular markers

The phenotypic and genotypic variability of olive tree cv. Leccino (Olea europaea L.), an ancient cultivar from North-Central Italy, was investigated using 44 quantitative and qualitative agro-morphological traits, SDS-PAGE of seed proteins (storage proteins and tegument proteins) and molecular markers such as RAPDs (30 primers) and SSRs (8 primers). Fifteen accessions of Olea europaea catalogued as "Leccino" and one certified tree of "Leccino" (LESt) were examined. The plants were clonally propagated and the measuring of all morphological characteristics was conducted over a period of seven years. The ANOVA analysis showed that all accessions were homogenous for many traits while very few …
