Relationship between Phosphorus and Nitrogen Concentrations of Flax

چکیده
Tools quantifying phosphorus (P) status in plants help to achieve efficient management and optimize crop yield. The objectives of this study were establish the relationship between P nitrogen (N) concentrations flax (Linum usitatissimum L.) during growth season determine critical concentration for diagnosing deficiency. Field experiments arranged as split plots based on a randomized complete block design. Phosphorus levels (0, 40, 80, 120, 160 kgP2O5 ha−1) assigned main plots, cultivars (Dingya 22, Lunxuan 2, Longyaza 1, Zhangya Longya 14) allocated subplots. Shoot biomass (SB) N determined at 47, 65, 74, 98, 115 days after emergence. increased, while N:P ratio declined with time each year. respect was described using liner (P = 0.05, + 1.68, R2 0.76, p < 0.01) under non-limiting conditions, which are expressed g kg−1 dry matter (DM). fitted second-order polynomial equation (N:P 11.56 × SB−0.1, 0.71, 0.03), SB flax. This research first developed predictive model flax, function shoots can be used promising alternative tool quantify degree deficiency current growing season.

Relationship between Hyperspectral Measurements and Mangrove Leaf Nitrogen Concentrations
The use of spectral response curves for estimating nitrogen (N) leaf concentrations generally has been found to be a challenging task for a variety of plant species. In this investigation, leaf N concentration and corresponding laboratory hyperspectral data were examined for two species of mangrove (Avicennia germinans, Rhizophora mangle) representing a variety of conditions (healthy, poor cond...
