“…Moreover, germination percentage increased when the seeds were hydroprimed and bioprimed with different strains of rhizobacteria. This result is significant considering that A. religiosa is a recognized species with slow germination (listed as extremely slow) during their stay in the nursery [54]. In contrast, A. hickelii is reported to be low, between 10% and 20% of total seed germination [55].…”

Abies spp. in general have been shown to need a period of cold stratification to break dormancy and germinate, but this can be very time consuming. In this study, hydropriming by itself and in combination with biopriming was carried out on Abies hickelii and Abies religiosa seeds. For biopriming, three species of plant growth promoting rhizobacteria ( Pseudomonas fluorescens, P. putida and Bacillus subtilis) were tested. The purpose was to determine if germination and growth could be improved for these two endangered species. Our results demonstrated that treating A. hickelii and A. religiosa with both hydropriming and biopriming with certain strains of Plant Growth-Promoting Rhizobacteria (PGPR) could improve germination rates up to 91% for A. hickelii and up to 68% for A. religiosa. Importantly, these treatments showed no significant negative impact on the growth of A. religiosa and actually improved growth in A. hickelii. The application of OPEN ACCESSForests 2015, 6 3110 both hydropriming and biopriming offer possibly an alternative methodology to improve germination, survival and preservation of these fir tree species of Mexico that are at risk of extinction.

“…The Dickson quality index (DQI) has also been widely used as an indicator of seedling quality [3,4], since it is calculated based on the robustness and equilibrium of phytomass distribution, and highly correlated with all plant morphological characteristics [5]. In addition to an adequate sampling method, a correct nutritional diagnosis obtained from the results of plant tissue analysis requires the establishment of criteria to interpret the findings [6].…”

The efficiency of methods in adequately interpreting the nutritional status of Eucalyptus spp. rooted cuttings remains unknown. The aim was to evaluate the quality of diagnoses obtained using the critical level (CL), diagnosis and recommendation integrated system (DRIS) and compositional nutrient diagnosis (CND) methods to assess the nutritional status of Eucalyptus spp. rooted cuttings, based on two different yield indicators. The data were obtained from commercial nursery and calibration experiments, using seven nutrients as treatments (N, P, K, Mg, Ca, B and Fe) and four concentrations per nutrient, arranged in randomized blocks, with four repetitions. The Eucalyptus spp. clone used in the experiments was AEC 0144. A total of 222 rooted cuttings were obtained from the experimental area and commercial nurseries and the following were determined: leaf nutrient content, whole plant dry matter (DM) content and the Dickson quality index (DQI). Diagnostic accuracy in the experimental plots was ascertained by comparing the diagnosis with plant response as a function of adding the corresponding nutrient. Five measures of accuracy were used to test the efficiency of the diagnostic methods: total accuracy, accuracy for deficiency and sufficiency, deficiency ratio, efficiency ratio, and the net increase in in DM and DQI. The performance of diagnostic methods varied between CL, DRIS and CND, and among the nutrients studied. Given that the seedling production system is largely more controlled, where environmental variations are minimal, and considering that the different diagnostic methods exhibited distinct performance in terms of assessing the true nutritional status of eucalyptus rooted cuttings, the CL method is the most indicated for this situation, due to its better performance in evaluating the nutritional status of most nutrients and easy implementation.

“…System (DRIS) son dos de las técnicas más utilizadas para dicho diagnóstico en los taxa forestales, y han dado buenos resultados tanto en plantaciones comerciales, como en bosques naturales (Moreno et al, 2002;Osiecka et al, 2019). Las primeras se refieren a las concentraciones foliares de nutrimentos, con las que se obtiene un rendimiento entre 90 y 100 %, respecto al rendimiento potencial (Medina-Morales, 2004) y son particulares para cada taxon y nutrimento; sin embargo, en el caso de C. odorata se desconocen los valores.…”

El diagnóstico nutrimental ayuda a mejorar la eficiencia del uso de fertilizantes en plantaciones forestales y a incrementar tanto las utilidades económicas, como los beneficios ecológicos. Dos métodos comúnmente usados, para tal efecto, son las concentraciones críticas y el Sistema Integrado de Diagnóstico y Recomendación (DRIS); sin embargo, no existen estudios que aporten los valores críticos o normas DRIS para Cedrela odorata (cedro rojo), especie importante en las regiones tropicales. El objetivo del presente estudio fue desarrollar un conjunto de concentraciones críticas y uno de normas DRIS para C. odorata en su etapa de medio turno. El estudio se realizó con 74 árboles localizados a lo largo del área de distribución natural del taxon en México, a los cuales se les determinó el incremento diamétrico y la concentración nutrimental entre julio de 2017 y enero de 2018. Se derivó un conjunto de concentraciones críticas y uno de normas DRIS. Una segunda fase fue la verificación de las concentraciones críticas y normas DRIS generadas, mediante un experimento en una plantación de cedro rojo de medio turno. El ensayo fue completamente al azar con arreglo factorial 3 × 4, en el que los factores correspondieron a la aplicación de P y K, respectivamente. Se presenta un conjunto de concentraciones críticas y uno de normas DRIS para árboles de C. odorata de medio turno. El proceso de verificación indica que ambos conjuntos de valores de referencia predicen correctamente el estado nutrimental de los árboles de medio turno del cedro rojo.
