General objective

 

The general objective of the group is the knowledge of plant natural strategies that have a bearing in agriculture and the study of genetic resources in fruit tree species.

 

Specific objectives

 

1. Reproductive Biology

 

M. Herrero

mherrero@posta.unizar.es

 

The study of reproductive biology is integrated with its agronomic implications. The hypothesis to evaluate is that the flower hosts a number of mechanisms that regulate male-female interaction and are responsible for the regulation of offspring production and hence of crop production.

 

Activities:

 

-    Pollination requirements and pollinator cultivars.

 

-    Study of the mechanisms that regulate male-female interaction.

 

-    Factors that interfere in the process of fruit set: temperature and nutritive status. While this line will continue to contribute transfer of knowledge to users, emphasis also will be given to address the study of strategies unveiled by the group and that are conserved in flowering plants.

 

2. Genetic Resources

Activities:

 

-    Recovery of jeopardize genetic resources.

 

-    Characterisation of plant material in cherrys, plums, apricots, and rootstocks from the genus Prunus

 

-    New plant material: a clonal selection and an evaluation of offspring in apricot (in collaboration with CITA), selection for a hybrid rootstocks plum x apricot, and selection of a kiwi pollinator (in collaboration with SERIDA-Asturias). This line will clearly provide a rich genetic substrate to provide answers to new questions addressed by users.

 

3. Early selection

 

J.A. Marin, A. Arbeloa, P. Andreu

jmarin@eead.csic.es

 

The rapid increase of new cultivars and rootstocks, together with the slow and expensive processes of selection prompts to the search for new strategies for an early selection of plant material. The group uses in vitro culture to address this point.

 

Activities:

 

-    Characterization of the processes involved in organogenesis.

 

-    Histochemical studies on the adaptive response to the environment.

 

-    Selection for tolerance to chlorosis, salinity and asphyxia. This line also will continue to provide consultancy facilities to the nursery industry interested in implementing these facilities.
