In Ecuador, the quality and quantity of information both climate soils is very general, so greater precision for decision making processes required in forest agricultural production. This review examines characteristics volcanic from along an altitudinal gradient. Soils were analyzed seven locations, including sites Coastal Sierra regions. These selected trying to include places with contrasting weather conditions but maintaining similar soil parent material. It was concluded that most...
Understanding the biology of pollen is necessary to optimize reproduction plants and successful implementation conservation breeding programs.In order have information on morphological characteristics viability in Nothofagus nervosa, male flowers trees established a clonal seed orchard were collected.Morphological characterization was carried out from observations under light microscope scanning electron microscope.Motic Images Plus 2.0 software used for measurements.Viability assessed by...
Cocoa is a primary source of economic income in the agricultural and agroindustrial sectors Ecuador. However, cocoa crops are vulnerable to meteorological conditions that affect reproduction processes, including pollen production, which has encouraged study factors related low crop yields practical implications breeding programs. The objective this was assess production per flower 11 genotypes <em>Theobroma cacao</em> national type CCN-51 clone. number grains estimated by...
The species of Scolytinae subfamily have a worldwide distribution, and are found mainly in the Neo-tropic regions. They usually dominate communities wood borer insects. aim present study was to determine diversity among associated with balsa, teak, rubber gamhar plantations located humid tropical zone Ecuadorian littoral. In each plantation seven flight interception traps containing an ethanol / gel mixture were installed, collection frequency 15 days for three months dry period. A total...
En Ecuador, el sistema de educación superior ha experimentado una gran expansión tanto en número estudiantes que aspiran obtener un título universitario como instituciones públicas (IPES). La mayoría las cuales son financiadas por estado, históricamente asignado forma imparcial los presupuestos beneficiando a IPES consideradas tradicionalmente elitistas, su proceso selección estudiantes. El objetivo la investigación fue establecer impacto del efecto Mateo durante período 2014-2018....
Long-term pollen storage is important so that producers and breeders may be able to utilise stored cross individuals bloom at different times or in places. The objective of the current study was determine moisture content optimal temperature for Nothofagus alpina (P. et E.) Oerst pollen. Pollen samples used this were obtained from established trees 'Huillilemu' clonal seed orchard, located commune San José de la Mariquina, southwestern Chile. extraction conducted by placing it a climatic...
Reproductive biology knowledge of species is essential for in situ conservation, propagation and breeding.Consequently, we describe the first detailed phenology Nothofagus alpina, mentioned until now only general terms, provide morphological description male female flowers.The study was conducted 2011 Clonal Seed Orchard "Huillilemu" located locality San José Mariquina, Region Los Ríos, Chile, at 23 meters altitude.Observations were made six clones orchard.The model proposed presents ten...
The potential production of pollen per plant is a good indicator fruit production.In this work the reproductive efficiency index, average flower and functional relationship between number anthers amount Nothofagus alpina were determined.The ratio viable seeds formed after manual pollination by natural was calculated.The total grains estimated direct counting.The index at an 0.19.It found that anther varied among individuals years.Pollen 85,703 in 2011 117,975 2013.Low seed open could be due...
Se implantó un ensayo de sistema agroforestal con café (Coffea arabica L.) en el área del cantón Quevedo, la Finca Experimental “La Represa”, año 1997. plantaron cuatro especies forestales asociación (C. L.), y también se establecieron parcelas árboles monocultivo, contiguas. Las utilizadas fueron guayacán blanco (Cybistax donnell-smithii Rose), laurel prieto (Cordia megalantha Chadat), fernansánchez (Triplaris cumingiana Wedd) teca (Tectona grandis L. F.). El objetivo fue comparar...
Three Gossypium species have been used to breed cotton as they vary in their fiber production and resistance stresses. Transcription factors (TFs) mostly are present different copies or isoforms by which conduct regulation. Their copy number can determine organism behavior a cue. Simple sequence repeats (SSRs) one of the most informative versatile molecular markers. three were compared silico. Seventy eight percent TFs common between species. Single for each 6057 TF. hirsutum G. raimondii...
Abstract Lapageria rosea is an emblematic species, endemic to the temperate rainforest of Chile. As a result extensive plantation commercial exotic pine and eucalypts, scattered individuals L. are now encountered mainly in fragmented forest areas. Therefore, has been declared danger extinction. However, success national conservation programs depends, part, on availability stored viable pollen grains for pollinating assays, order sustain genetic diversity offspring. Here we describe simple...
Understanding pathways of genetic information transfer from one generation to another is particularly important when open-pollinated seeds are collected for reforestation or enrichment native forests. Nothofagus alpina (Poepp. & Endl.) Oerst. temperate forests southern Chile and Argentina. However, lack knowledge its reproductive biology has hampered management in forest plantations conservation natural populations. Therefore, a clonal seed orchard N. was used analyse the mating system...
