El análisis de pigmentos en plantas es un procedimiento de laboratorio y comúnmente no es una medida inmediata que se realice in situ. El SPAD 502 y CCM-200 son equipos para estimar de modo indirecto, no destructivo y rápido el contenido de clorofila. La concentración de pigmentos fotosintéticos se relaciona con la concentración foliar de nitrógeno, por lo que de forma indirecta se puede conocer la deficiencia o exceso del elemento, puede servir como fundamento técnico para sugerir el manejo adecuado del cultivo, en busca de potencializar la eficiencia fotosintética, calidad y el rendimiento de un viñedo. La investigación buscó comparar las mediciones entre el medidor portátil de clorofila SPAD-502 y CCM-200, en la variedad de uva Riesling Becker, bajo condiciones de clima frío tropical, y con ello determinar el comportamiento de clorofila durante el crecimiento de las hojas 4, 5 y 6, desde floración hasta vendimia. La relación entre las mediciones con el SPAD- 502 y el CCM-200 se ajustaron a un polinomio de segundo grado determinado por la ecuación, para el Índice de Concentración de Clorofila, como ICC = 0,014SPAD2-0,2396SPAD+5,8021. Con un valor de R2=0,9343 (n=96; P≤0,0001), el cual indica que existe una alta correlación entre los equipos portátiles empleados en el presente estudio para determinar la clorofila de forma no destructiva. Las evaluaciones realizadas con los equipos permitieron obtener medidas rápidas y confiables. Siendo importante la elección del momento de medición de acuerdo con el estadio fenológico de la planta debido a la alta variabilidad en los contenidos de clorofila que se presentan en relación a la filotaxia.

“…leaf area, chlorophyll content) of plants change gradually. Previous studies have found that leaf area as well as chlorophyll content have critical effects on the contents of primary and secondary metabolites of crops ( Munz et al, 2018 ; Senger et al, 2014 ; Hudina and Štampar, 2002 ). For S. baicalensis , its capacity of sugar biosynthesis increases with growing leaf area and chlorophyll content, thereby increasing the contents of secondary metabolites (e.g.…”

“…We found that flowering onset, biomass, and chlorophyll content were clearly heritable in W. ceracea . Chlorophyll content is proportional to the concentration of photosynthetic pigments and nitrogen in a leaf (Ling et al ., 2011); it is heritable in wheat (Rosyara et al ., 2010; Said et al ., 2022), and has a relatively strong relationship with flowering in other crop species (Senger et al ., 2014). To the best of our knowledge, there has not been another study reporting the heritability of chlorophyll content in a wild species, but our findings here suggest that variation in photosynthetic pigment concentration at least has a genetic basis.…”

Phenotypic plasticity and rapid evolution are fundamental processes by which organisms can maintain their function and fitness in the face of environmental changes. Here we quantified the plasticity and evolutionary potential of an alpine herbWahlenbergia ceracea. Utilising its mixed-mating system, we generated outcrossed and self-pollinated families that were grown in either cool or warm environments, and that had parents that had also been grown in either cool or warm environments. We then analysed the contribution of a range of environmental and genetic factors to variation in nine phenotypic traits including phenology, leaf mass per area, photosynthetic function, thermal tolerance, and reproductive fitness. The strongest effect was that of current growth temperature, indicating strong phenotypic plasticity. All traits except thermal tolerance were plastic, whereby warm-grown plants flowered earlier, grew larger, produced more reproductive stems compared to cool-grown plants. Flowering onset and biomass were heritable and under selection, with early flowering and larger plants having higher relative fitness. There was little evidence for transgenerational plasticity, maternal effects, or genotype-by-environment interactions. Inbreeding delayed flowering and reduced reproductive fitness and biomass. Overall, we found thatW. ceraceahas capacity to respond rapidly to climate warming via plasticity, and the potential for evolutionary change.HighlightWe found strong plasticity to growth environment in many phenotypic traits, but little effect of parental environment, revealing capacity to respond rapidly to climate warming, and potential for evolutionary change.
