“…Perennial species fertilizations should be thoughtful, observing the use of nutrients by the varieties during vegetative and reproductive growth, and aiming to promote the development and productivity of the trees. The excessive application of chemical fertilizer without consideration of the phenological variability of plants and features related to the area of cultivation leads to increased production costs and environmental risks (Boussadia et al 2010).…”

“…Since soil-plant analysis development (SPAD) linearly relates to Chl content, meter-read values represent N concentrations in leaves (Du et al, 2009). Therefore, SPAD is a useful tool for rapidly and non-destructively measuring leaf Chl content to evaluate fertilization efficiency (Boussadia et al, 2010). This technique has been extensively employed to evaluate the N demand of many crops, such as corn and wheat (Chen et al, 2010), rice (Yang et al, 2014), potato (Zeng et al, 2015), and geranium (Wang et al, 2012).…”

The objective of this study was to predict the timing of nitrogen (N) demand through analyzing chlorophyll fluorescence (ChlF), soil-plant analysis development (SPAD), and normalized difference vegetation index (NDVI), which are positively correlated with foliar N concentration in star cluster (Pentas lanceolata). The plants were grown in potting soil under optimal conditions for 30 d, followed by weekly irrigation with five concentrations (0, 4, 8, 16, and 24 mM) of N for an additional 30 d. These five N application levels corresponded to leaf N concentrations of 2.62, 3.48, 4.00, 4.23, and 4.69%, respectively. We measured 13 morphological and physiological parameters, as well as the responses of these parameters to various N-fertilizer treatments. The general increases in Dickson's quality index (DQI), above-ground dry weight (DW), total DW, flowering rate, △F/Fm', and qP in response to treatment with 0 to 8 mM N were similar to those of SPAD, NDVI, and Fv/Fm. Consistent and strong correlations (R 2 = 0.60 to 0.85) were observed between leaf N concentration (%) and SPAD, NDVI, △F/Fm', and above-ground DW. Validation of leaf SPAD, NDVI, and △F/Fm' revealed that these vegetation indices are accurate predictors of leaf N concentration that can be used for non-destructive estimation of the proper timing for N-solution irrigation of P. lanceolata. Moreover, irrigation with 8 mM N-fertilizer is recommended when leaf N concentration, SPAD, NVDI, and △F/Fm' ratios are reduced from their saturation values of 4.00, 50.68, 0.64, and 0.137%, respectively.

“…N limitation may lower net photosynthesis by decreasing photosynthetic pigment contents (Zhao et al, 2005;Yao & Liu, 2006;Cabrera-Bosquet et al, 2009). Further increased nitrogen fertilizer does not increase photosynthetic pigments and photosynthesis (Correia et al, 2005;Dordas & Sioulas, 2008;Boussadia et al, 2010). The effect of N levels on photosynthesis is manifested in differences in the stomatal conductance and the intercellular carbon dioxide (CO 2 ), but the results are not consistent between different plant species (Zhang et al, 2013).…”

Excessive nitrogen supply has resulted in environmentally negative impacts. In order to select and develop N-efficient ramie cultivars in increased N application environments, the morphological, physiological and biochemical responses of a ramie hybridization line (Chuanzhu 11) and its conventional parents (C9451 and R79-20) to N fertilizer were investigated under rain-fed conditions during three consecutive growing seasons. Two contrasting nitrogen levels (low nitrogen, LN: 20kg ha -2 ; high nitrogen, HN: 120kg ha -2 ) were used. Results indicated that high N substantially promoted the growth of ramie plants and led to remarkable increase in fiber yield in all cultivars during the three growing seasons. Such increase was also recorded in net photosynthesis, transpiration rate and stomatal conductance, as well as chlorophylls and carotenoids. However, high N supply caused no alteration or increase in intercellular CO 2 (C i ) and C i / C a (ambient CO 2 ) ratio, depending on species. Moreover, high N application significantly improved soluble protein and proline content while it reduced malondialdehyde content. The activities of superoxide dismutase and catalase also elevated, whereas peroxidase activity decreased by high N application in all cultivars. Furthermore, hybrid cultivar Chuanzhu 11 exhibited better performance as compared to its parents C9451 and H7920 due to improved growth, fiber yield, leaf gas exchange traits and enzymatic and non-enzymatic antioxidant systems under high N supply conditions. In conclusion, ramie hybrid cultivar Chuanzhu 11 was more efficient to absorb and utilize high levels of N. This meets the need for uptake and utilization of high concentration of N in increased N fertilizer environments.
