Testing of germination of spruce, pine and larch seed after 10 years from collection

Abstract

:Germination capacity and germination energy are usually the most frequently used quantitative parameters of forest tree seed. With seed ageing both parameters decreased and the rate of the collapse is given by tree species, age of tree and its seed and biotic and abiotic factors. Relatively little attention has been paid to the age of seed. As it was found, the longevity of the main tree species remained relatively high, and spruce (Picea abies [L.] Karsten and pines (Pinus sylvestris L.) from the investigated areas across the Czech Republic maintained minimally one third of germination capacity or germination energy during the 10 years with the exception of larch (Larix decidua Mill.) where germination capacity decreased almost to zero after 10 years. Although the germination energy and germination capacity decreased significantly, it is possible to use the seed in the case of shortage of the seed of better quality.  

Responses of the germination and phytochemical content of Pinus nigra Arn. subsp. pallasiana (Lamb.) Holmboe. (Anatolian black pine) seeds to salt stress

“…As a result, both the growth and development processes of the plants, as well as their natural spread process, are negatively affected (Chen et al 2019). Among the most frequently used quantitative parameters of forest tree seeds, various germination data, such as the germination capacity and germination energy, are used (Tomášková et al 2014), and the germination success of plants can be determined in their ecological environment. For this reason, new data on future plant germination and propagation modelling describing the germination success of Pinus nigra Arn.…”

Evaluation of pre-germination treatments on four native species of the High Andean forest

“…This variability is likely attributed to morphological and physiological responses of seeds to substrates and pre-germination treatments. Furthermore, the environmental conditions of site and the collection of seeds directly from the wild forest (i.e., without silvicultural management or genetic improvement) can also contribute to this variability (Tomášková et al, 2014). Mancipe-Murillo et al (2018) reported different germination percentages, ranging from 25 to 100%, for native species from the High Andean Forest.…”

Variabilidad intraespecífica en la calidad de semillas de especies forestales nativas en bosques montanos en el sur del Ecuador: Implicaciones para la restauración de bosques

“…(Julio-Diciembre, 2017 Por otro lado, si bien los árboles madre en nuestro estudio tuvieron características fenotípicas similares, hay factores que pudieron influir en los resultados como posibles explicaciones de la variabilidad, que no fueron medidos en este estudio pero en la bibliografía se refieren a la influencia genética de los árboles madre (Gutterman, 2000;Ivana Tomášková, Vítámvás & Korecký, 2014a), a la edad de árboles (Masilamani, Bhaskaran, Chinnusamy & Annadurai, 2000;Tomášková, Vítámvás & Korecký, 2014b) o a la posición de los árboles dentro del bosque, pues se conoce que los arboles dominantes pueden tener sobre los demás una mejor absorción y eficiencia de luz (Campoe et al, 2013).…”
