“…In the present study, the chestnut shoots cultured by CIS showed statistically significant higher levels of total phenolic compounds relative to those cultured by TIS: however, the differences were small, and no variation was detected between sucrose treatments. Higher phenolic content has been correlated with a plant’s defensive response to suboptimal conditions either in vivo [ 61 , 62 , 63 ] or in vitro [ 64 ], although not all plants follow this pattern, and high accumulation of phenolic compounds has been reported with the optimal performance of tara microshoots [ 65 ]. Similarly, in rose, more phenolics were detected in shoots cultured by TIS, which showed a better performance, than by CIS [ 66 ].…”

Current breeding programs aim to increase the number of ink-tolerant chestnut trees using vegetative propagation of selected genotypes. However, the commercial vegetative propagation of chestnut species is still a bottleneck for the forest industry, mainly due to problems in the rooting and acclimation of propagules. This study aimed to explore the potential benefits of decreasing sucrose supplementation during chestnut micropropagation. Explants were cultured with high light intensity and CO2-enriched air in temporary or continuous immersion bioreactors and with different sucrose supplementation to evaluate the impact of these treatments on growth, rooting and physiological status (monosaccharide content, soluble phenolics and antioxidant activity). The proliferation and rooting performance of shoots cultured by continuous immersion decreased sharply with sucrose concentrations lower than 1%, whereas shoots cultured by temporary immersion grew and rooted successfully with 0.5% sucrose. These results suggest this system is appropriate to culture chestnut with low sucrose concentration and to explore photoautotrophic propagation of this species.

“…Se ha definido el mejor tipo de injerto, la edad de los patrones y de las ramas productoras de yemas (Flores et al, 2005b;Sernaqué-Aba-die et al, 2020). El cultivo in vitro para propagación clonal está en sus inicios Núñez-Ramos et al, 2020) y es una buena posibilidad para abastecer la demanda de material para nuevas plantaciones. También, la "tara" se asocia eficientemente con hongos micorrícicos del género Rhizophagus (Glomeraceae) y su aplicación en plántulas mejora la absorción de P y N y su crecimiento y, puede ser una práctica agronómica importante para mejorar la productividad (Sangay et al, 2017).…”

La “tara” o “taya” (Tara spinosa) es una planta económicamente importante para el Perú y otros países andinos, aprovechada en su estado silvestre, principalmente. Sin embargo, no se conoce sobre su origen y dispersión y, el estado de domesticación, como base para entender los cambios que surgirán debido a su cultivo intensivo con tecnología mejorada y para su conservación. En este artículo, sobre la base de fuentes biológicas, arqueológicas, lingüísticas e históricas y, observaciones de campo; se esclarece, por primera vez, sobre estos aspectos. También se expone sobre la dirección de las presiones de selección, el enfoque de las investigaciones al respecto y los estudios pendientes. Se concluye provisionalmente que su centro de domesticación se ubica en la costa peruana, en donde la relación hombre-”tara” data de 5100 años. Todavía no ha alcanzado el nivel de planta domesticada en alto grado y es posible encontrarla además del estado silvestre, en cuatro estados intermedios. Se sugieren los estudios para conocer mejor la variabilidad del germoplasma, con atención a las partes útiles, sus componentes y principios activos.
