Romero rastrero reproduccion asexual

opinion

Jaime Prohens Tomas Dr. Santiago Vilanova Navarro Dra. Increasingly fewer species are cultivated, and these are also increasingly homogeneous. The introduction of new crops for the horticultural diversification is one of the activities that can be implemented to minimize the impact of this variability loss. In this regard, pepino Solanum muricatum is a crop "Romero rastrero reproduccion asexual" may be of interest to our horticulture and neighboring markets.

It is a species of Andean origin, usually propagated vegetatively, and that can be grown in the Mediterranean area. The pepino is used for its juicy, sweet and aromatic fruits, which in addition presents significant amounts of beneficial compounds for health.

At present, morphological descriptors are available for proper characterization of these materials, but it was necessary to develop phenological descriptors as the ones presented in this work. In particular, the BBCH scale developed in this thesis is a key that allow us to describe and define the various stages of phenological development "Romero rastrero reproduccion asexual" the species, displaying numerous applications.

On the other hand, a correct characterization of the accessions preserved in the genebank was necessary. For this reason, and in addition to carrying out a morphological characterization, a molecular characterization using SSR markers derived from tomato was performed.

In this case, the benefit of the genetic proximity between the two species allowed us to transfer the tomato markers widely studied species to pepino, allowing us to differentiate morphologically and molecularly the wild species from the cultivated one, and within the latter, differentiate modern and traditional types. A limitation in the study of the genetics of pepino was the small Romero rastrero reproduccion asexual of DNA Romero rastrero reproduccion asexual available in Romero rastrero reproduccion asexual databases.

For this reason, we sequenced the transcriptome of a variety of pepino Sweet Long as well as the species that is considered the wild ancestor of the pepino, S. The sequencing and subsequent Romero rastrero reproduccion asexual of the transcriptome has allowed an initial comparative analysis between pepino and its closely related species, tomato and potato, a phylogenetic study of cultivated Solanaceae, a comparative analysis of some genes of agronomic interest, and the massive development of molecular markers.

We have evaluated the dry matter, protein, antioxidants, pigments and minerals contents. On the other hand, considering that polyphenols are one of the Romero rastrero reproduccion asexual important antioxidant compounds, we conducted a study trying to elucidate the profile of polyphenols and their antioxidant activity in four pepino and one S. We also measured the effect of the pepino extracts on macrophage Romero rastrero reproduccion asexual subjected to oxidative stress.

The results obtained revealed a significant reduction in nitric oxide production, which indicates the existence of an anti-inflammatory effect. These beneficial properties of pepino are its main strength and, together with a high organoleptic quality and good promotion can encourage the introduction and development of this crop. In summary, in this thesis we have obtained relevant information about the diversity of pepino and we have studied its phenological, morphological, molecular, genomic, nutritional and nutraceutical characteristics.

We believe that this information will Romero rastrero reproduccion asexual useful in the development and recovery Romero rastrero reproduccion asexual this neglected crop. Comprehensive analysis and comparison with closely related potato and tomato genomes Fruit composition diversity in local and modern pepino Solanum muricatum varieties and wild related species Phenolics profile and antioxidant and biological activities of the fruit of pepino Solanum muricatum and its wild relative S.

Un patrimonio perdido para las generaciones futuras, que es irreversible en algunos casos y muy grave en el resto. Kuntzeel lulo o naranjilla Solanum quitoense Lam. Como ya se ha comentado, en la actualidad, las necesidades de alimentos recaen en unas pocas especies, dejando en desuso otras muchas. El abandono por parte Romero rastrero reproduccion asexual los agricultores de las variedades que cultivaban tradicionalmente, ha supuesto que muchas de ellas se pierdan irremediablemente.

Son los bancos de germoplasma o bancos de semillas las instituciones encargadas de recoger y conservar estos Romero rastrero reproduccion asexual. En esta tesis se ha empleado este descriptor para un estudio de la diversidad de 6. Inicialmente fue desarrollada una clave general Hack et al.

La diversidad o variabilidad entre organismos se debe al efecto combinado del medioambiente y a diferencias en la secuencia de ADN. Son marcadores que presentan muchas ventajas: En el caso del pepino dulce se han utilizado en varios trabajos. Por ejemplo Blanca y colaboradores en Blanca et al. En otro trabajo de Prohens y colaboradores en Prohens et al. En cualquier caso tanto para un proceso como otro se requiere un periodo largo tiempo.

Estas especies son las Romero rastrero reproduccion asexual Es la especie que presenta menos diferencias de cariotipo con S.

La tabla 1 muestra el contenido en otros compuestos menos importantes cuantitativamente Redgwell y Turner, Estas propiedades se han convertido en un objetivo prioritario en la mejora del pepino dulce, cosa que puede estimular su demanda Manejo del cultivo.

Cabe indicar que es una "Romero rastrero reproduccion asexual" que se adapta perfectamente a cultivo bajo invernadero. En general la planta se adapta muy bien al riego por goteo y no es muy sensible al exceso de humedad o encharcamiento. En general se puede decir que existen muchas plagas y pocas enfermedades que pueden atacar al pepino dulce.

A pesar de su larga historia, sigue siendo en esas zonas un cultivo marginal, sobre el que no se han realizado programas de mejora, por lo que no existen nombres diferenciados para los distintos cultivares, o bien estos se han perdido. De Romero rastrero reproduccion asexual forma se distinguen dos variedades: Con pulpa amarilla muy dulce, muy apreciados.

Prohens Scientia Horticulturae,. We provide a detailed description of phenological stages because it is of interest for pepino crop management and research. Given the increasing prominence of this crop, and the fact that it morphologically and developmentally variable, and different from other major solanaceous crops, we have developed a pepino specific BBCH Biologische Bundesanstalt, Bundessortenamt, CHemische Industrie numerical scale.

Secondary stages twodigit scale have been identified for all principal stages. Complementary descriptions using mesostages three-digit scale have been Romero rastrero reproduccion asexual for leaf development, formation of side shoots, inflorescence emergence, and flowering phenological stages.

A description of all phenological stages Romero rastrero reproduccion asexual with illustrations is provided. The utility of the BBCH scale has been validated by comparing several traits of agronomic interest at specific developmental stages in a collection of pepino local varieties, modern cultivars and wild relatives.

The BBCH scale developed provides uniform criteria for the description, identification and selection of phenological stages of the pepino and will facilitate the management, breeding and conservation of genetic resources of this crop. Introduction The pepino Solanum muricatum Aiton is an herbaceous crop domesticated in the northern Andes, where its closest wild relatives, from Solanum section Basarthrum also thrive Anderson et al.

The pepino can be very variable in shape Romero rastrero reproduccion asexual colour, and is mostly consumed when fully ripe as a fresh fruit. At maturity, it has a characteristic mild sweet flavour and intense fruity aroma, which has some resemblance to that of melon Prohens et al.

As for other emerging crops, there is The pepino has a number of specific features that distinguish it from major solanaceaous fruit crops such as tomato S.

These include vegetative propagation; in agricultural practice, the pepino is usually propagated Romero rastrero reproduccion asexual cuttings which root easily when placed in a wet substrate. An alternative way of clonal propagation is the use of in vitro micropropagation, which allows the production of disease free plants Cavusoglu and Sulusoglu, Also, the pepino grows luxuriantly, and such vegetative growth may compete with fruit set, so the highest yields are obtained when the lateral sideshoots are removed, nitrogen fertilization is controlled to avoid excessive vegetative growth, and Romero rastrero reproduccion asexual plants are trained with vertical strings using a one or two main shoot system Kowalczyk and Kobryn, Another difference Romero rastrero reproduccion asexual major solanaceous fruit crops is that many pepino cultivars display a strong tendency to parthenocarpy, with some cultivars obligately parthenocarpic Prohens et al.

In addition, the pepino fruit needs a long time up to 70 days to fully Romero rastrero reproduccion asexual since. Finally, fruit quality, especially sugar concentration, may be influenced by temperature during ripening; high temperatures result in a lower sugar content and in the development of an off-flavour Rodriguez-Burruezo et al. The development of characterization tools for the precise and standardized description of the pepino plants and fruits is essential for an increased efficiency and effectiveness of research experiments, breeding programmes, conservation of germplasm and for the comparison of experimental data Gotor et al.

Although this list is useful for the description of characteristics of pepino varieties and wild relatives and for the study of the morphological variation in collections and segregating generations, no standardized scales to precisely describe the phenological stage of pepino plants, which would be of great utility for agronomic and botanical research Meier,are available. The BBCH Biologische Bundesantalt, Bundessortenamt und Chemische Industrie scale for the phenological identification of the growth stages of all species of mono- and dicotyledonous plants Lancashire et al.

This scale uses 10 principal stageseach of which is further divided into 10 secondary An extended BBCH-scale, using mesostageswas proposed for some crops using a third-digit scale Meier, Both scales simple and extended have been developed and are widely accepted for many crops Meier et al. The development stages of pepino have not yet been defined and described. Material and methods 2. Plant material Phenological observations were made by the authors through a period of more than half a century initiated C.

Heiser in the s Heiser, and followed up by G. Anderson of pepino research, cultivation, evaluation and breeding of pepinos. These proposals are based on research that has included examination of pepino plants growing in different environments and cultivation conditions in its native home in the Andean region, as well under cultivation outside and in glasshouses in the USA, Spain, and a number of other countries.

This latter area has a typical Mediterranean climate, with mild winters and long warm and dry summers. Materials used Romero rastrero reproduccion asexual this trial included 14 "Romero rastrero reproduccion asexual" pepino varieties consisting of six local varieties from the Andean region and eight commercial cultivars. In addition eight accessions of the wild species most closely related to the domesticate pepino were studied, including: Anderson, Martine, Romero rastrero reproduccion asexual and Nuez one Romero rastrero reproduccion asexualS.

Pepino materials were vegetatively propagated in vitro and after acclimatization were transplanted in the greenhouse in 1 m deep benches filled with silica sand as substrate.

Wild relatives were germinated from seed and one individual was clonally propagated in vitro for the trial. For each of the pepino varieties and wild relatives, five plants were cultivated Planta rastrera y trepadora que crece principalmente en las zonas tropicales, cuyos si se trata de una representación femenina, masculina o asexuada.
