Nitrate influx in rose plants during day-night cycle

Journal of Plant Nutrition (2016)

Raúl Cárdenas‐Navarro Vilma del Carmen Castellanos-Morales Luis López‐Pérez Juan José Peña‐Cabriales F. CRUZ

In herbaceous plants grown in controlled environmental conditions nitrate (NO3−) uptake increases during the day and decreases in the night. The aim of this work was to measure NO3− uptake rates along the day-night cycle, in rose (Rosa hybrida L.) plants grown under controlled environmental conditions. Two independent experiments were conducted inside a growth chamber at 20 ºC and 25 ºC, using rose mini-plants cv. Texas, grown in a hydroponic nutrient film technique (NFT) set-up with at 3.0 mol m−3 NO3− concentration. Dry matter and nitrogen (N) accumulation were registered during growth and NO3− uptake rates were measured during a day-night cycle, using 15N as 15NO3−. In both experiments the hourly estimated N-NO3− accumulation rates are near to the measured uptake rates of 15NO3− and nitrate uptake decrease during the day and increase in the night, in contrast with the herbaceous plants. Results are discussed on the basis of N plant demand and carbohydrates availability.

ESTIMACIÓN DEL ESTADO NITROGENADO DE PLANTAS DE FRESA A PARTIR DE SU RESPUESTA ESPECTRAL

Revista Fitotecnia Mexicana (2006)

Ma. Luisa España-Boquera Luis López‐Pérez Vilma del Carmen Castellanos-Morales Raúl Cárdenas‐Navarro

La fertilización nitrogenada aportada al cultivo de fresa (Fragaria x ananassa Duch.) en Michoacán (México), excede con mucho las necesidades reales de las plantas, por lo que supone un gasto de producción excesivo y causa, además, graves problemas ambientales. Para optimizar el suministro de fertilizantes es necesario monitorear su estado de nutrición nitrogenada, lo cual se puede hacer con medidas espectrales que son rápidas, no destructivas y fáciles de automatizar. A partir de los espectros de hojas de plantas de fresa cultivadas en hidroponía con tres niveles de fertilización nitrogenada (0.1, 3 y 20 mM de N), se calcularon índices de vegetación en cuatro fechas de muestreo, y la correlación con los contenidos de nitrógeno y clorofila, así como con biomasa, área y densidad foliares. Las plantas cultivadas con 3 mM de N presentaron mejor desarrollo que las cultivadas con 0.1 mM de N, que mostraron un crecimiento más lento; las plantas con 20 mM de N presentaron un desarrollo similar al de las plantas con 3 mM de N. Entre los índices de vegetación calculados, las mejores correlaciones con el contenido de N en la materia seca, las presentaron la reflectancia en el verde (R550), el MTCI (MERIS Terrestrial Chlorophyll Index) y el REP (Red Edge Position), si bien este último presenta problemas de saturación.

Effect of the concentration and ionic form of nitrogen (N) on photosynthesis, growth and fruit production of blueberry (Vaccinium corymbosum L.)

BIOtecnia (2024)

Raúl Cárdenas‐Navarro Jesús Alonso Luna-Béjar Vilma del Carmen Castellanos-Morales Nayda Luz Bravo-Hernández Luis López‐Pérez

The aim of this work was to evaluate the main effects and the interactions of nitrogen (N) concentration and ammonium (NH4+): nitrate (NO3-) proportion in the nutrient solution, on net photosynthesis, plant growth, production and quality of fruits on blueberry (Vaccinium corimbosum L.) plants. The studied factors were N concentration (0.6 and 6.0 mM) and NH4+: NO3- proportion (100 % NH4+, 50 % NH4+ - 50 % NO3- and 100 % NO3-). 243 days after the experiment establishment net photosynthesis (PN) was measured and a day after, leaf area (LA), shoots fresh weight (SFW) and roots fresh weight (RFW) were determined. Fruit yield (FY), fruit diameter (FD) and Brix degrees (oBrix) were evaluated in four harvests along fruit production period. The results showed higher values on PN, LA, SFW, FY and FD in plants that received 6.0 mM N as NH4+; nevertheless, N concentration altered the NH4+: NO3- proportion effects and at 0.6 mM N only FY and FD maintained such a pattern. It is concluded that N concentration modifies the effect of NH4+: NO3- proportion and it is proposed that the effects of both factors on photosynthesis, growth and fruit production of blueberry were mediated by their interaction with plant carbohydrates availability.
