SUBSTRATE AND FERTILIZATION IN THE QUALITY OF Myrocarpus frondosus SEEDLINGS

Abstract: Myrocarpus frondosus is a native species with high commercial timber value. Thus, the objective of this research was to evaluate the quality of seedlings of Myrocarpus frondosus in the nursery and to indicate the most adequate substrate and fertilization for the production of seedlings. The experiment was conducted in a completely randomized design, with four replications, in a factorial scheme, composed of four combinations of substrates: S1-100% commercial substrate (CS); S2 - 80% CS and 20% carbonated rice … Show more

“…The availability of water in the substrate is a fundamental part of the processes of root and leaf emission, as well as the transport of water and nutrients via the xylem, providing conditions for the production of photoassimilates necessary for the growth and initial development of the seedling (Masiero et al, 2019). The function of the substrate is to provide adequate conditions for the development and growth of the plant root system (Aimi et al, 2019) T. stans proved to be nutrient dependent both in the initial phase of seedling emergence and in the subsequent development of the seedlings, as the highest averages of morphological characteristics were obtained in enriched substrates, mainly and the lowest averages in sand and vermiculite, substrates considered inert (Table 3). The substrate composition can change emergence, initial growth and the content of photosynthetic pigments, modifying the capture of radiant energy and influencing the amount of assimilates produced (Afonso et al, 2017).…”

“…Electrical conductivity, on the other hand, refers to an indication of the concentration of salts in the solution and provides a parameter for estimating the amount of nutrients present in the substrates (Pêgo et al, 2019) and, according to Gabira et al (2020), high values can negatively affect plant root growth, significantly influencing seedling quality. Aimi et al (2019) emphasize that the physical condition is important because the substrate must be porous, thus avoiding the lack of oxygen, and water availability to the roots. Sand presents high and vermiculite with low density (Kämpf, 2000), being verified for sand a density of 1333 kg m -3 and for vermiculite, 159 kg m -3 (Stumpf et al, 1999).…”

“…The use of CRF for native forest species seedling production has demonstrated significant benefits for plant growth compared to ready-release fertilizer (Aimi et al 2019). Furthermore, due to the characteristics of CRF, the gradual release of nutrients contributes to the reduction of leaching, maintaining nutrient in the substrate for an extended period (Jacobs and Landis 2009).…”

“…In order to meet this demand, substrates and fertilizers are essential in seedling production (Aimi et al 2019). However, it is ideal for forest species to characterize the combined effect of these factors (Barrett et al 2016) to optimize morphological and physiological responses, thus ensuring higher quality seedlings Macdonald 2018a, Aimi et al 2019).…”
