A cryopreservation protocol for immature zygotic embryos of species of Ilex (aquifoliaceae)
(Sociedad Latinoamericana de Microscopia Electrónica, 2008-04)Tropical Ilex species have recalcitrant seeds. This work describes experiments demonstrating the feasibility of long-term conservation of Ilex brasiliensis, I. brevicuspis, I. dumosa, I. intergerrima, I. paraguariensis, ... -
Conservación in vitro de germoplasma de té (Camellia Sinensis)
(Universidad Nacional del Nordeste. Facultad de Ciencias Agrarias, 2014)El objetivo de este trabajo fue establecer protocolos que permitan la regeneración in vitro de té, a partir de diferentes explantes y que permitan la conservación de germoplasma a corto/mediano y largo plazo. Debido a ... -
Cryopreservation of Arachis Pintoi (leguminosae) Somatic Embryos
(CryoLetters, 2013-01-06)In this study, we successfully cryopreserved cotyledonary somatic embryos of diploid and triploid Arachis pintoi cytotypes using the encapsulation-dehydration technique. The highest survival rates were obtained when somatic ... -
Effect of morphological heterogeneity of somatic embryos of melia azedarach on conversion into plants
(Sociedad Latinoamericana de Microscopia Electrónica, 2010-01-16)Embryogenic cultures were initiated from immature Melia azedarach (Meliaceae) zigotic embryos. Explants were induced on Murashige and Skoog (1962) medium with 4.54 μM thidiazuron or 0.45 μM dichlorophenoxyacetic acid. ... -
Organogenesis and plant regeneration of arachis villosa benth. (leguminosae) through leaf culture
(Sociedad Latinoamericana de Microscopia Electrónica, 2009-11-02)With the aim of developing an efficient plant regeneration protocol, leaflet explants of three accessions of Arachis villosa Benth. (S2866, S2867 and L97) were cultured on basic Murashige and Skoog medium supplemented ... -
Plant regeneration from ilex spp. (aquifoliaceae) in vitro
(Sociedad Latinoamericana de Microscopía Electrónica. Centro Regional de Investigaciones Científicas y Tecnológicas Mendoza, 2001)In vitro plant regeneration from nodal segments (containing one axillary bud) of seven species of the genus Ilex (l argentina, I. brevicuspis, I. dumosa, I. microdonta, I. pseudoboxus, I. taubertianb and I theezans ) were ... -
Plant regeneration of ilex paraguariensis (aquifoliaceaé) by in vitro culture of nodal segments
(Sociedades Latinoamericanas de Microscopia Electrónica. Centro Regional de Investigaciones Científicas y Tecnológicas, 2020-04)In vitro regeneration of complete plants ffom nodal single bud segments of “yerba mate” {Ilex paraguariensis St. Hil.) was studied under defined nutritional and environmental conditions. Nodal segments harvested ffom ... -
Respuesta del mutante aerial roots-1 de tomate (Solanum lycopersicum L.) a la inundación
(Universidad Nacional del Nordeste. Secretaria General de Ciencia y Técnica, 2013-06-12)La inundación es uno de los estreses abióticos más frecuentes y extensos, que influye negativamente en el crecimiento de plantas terrestres y en su productividad, afectando la composición de las poblaciones de plantas ... -
Sowing pyrenes under aseptic conditions enhances seed germination of Ilex brasi liensis, I. pseudoboxus and I. theezans (Aquifoliaceae)
(Seed testing. Association International, 2015-02)Seeds of Ilex species are individually enclosed by a woody endocarp, forming a dispersal unit termed a pyrene. Embryos are undeveloped when fruits reach maturity. As a consequence, germination is low even after several months ... -
Storage of cohniella cepula (Orchidaceae) Pollinia : fertilizing ability and subsequent fruit and seed formation
(American Society for Horticultural Science, 2016-10)Pollen storage is of great importance for plant breeding and production besides an efficient means for preservation of haploid gene pool of plant genetic resources and rare or endangered species. Pollinia of Cohniella ...
