Macadamia is a nut tree native to Australian rainforest. Due to the small wild populations and the economic interest, studies assessing genetic information are fundamental for use and conservation of this species. Therefore, the present study aimed to assess the structure and genetic diversity of 28 cultivars of macadamia originated from United States, Australia and Brazil, introduced or developed by the Agronomic Institute?s breeding program, using 29 new microsatellite loci. The microsatellite loci showed high genetic diversity (3.65 alleles per locus on average). Our results also suggested the existence of no genetic structure between cultivars, regardless of their geographic origin. The modified Rogers? distances between cultivars ranged from 0.227 to 0.671. Despite the lack of information about genealogy, the cultivars from this Brazilian germplasm showed moderate genetic diversity, so they can be used as parents in future crosses. |

The aim of this study was to develop a quantitative method to determine phosphorus in fertilizers of different matrix compositions using the laser induced breakdown spectroscopy (LIBS) technique. The LIBS spectra were acquired on 26 samples of organic and inorganic fertilizers by using a low cost, portable, gated CCD system in the atmospheric environment. Inductively coupled plasma optical emission spectroscopy (ICP-OES) was used as the reference technique. A method was developed to remove the outlier spectra and perform the baseline correction and peak normalization. By applying the proposed corrections, the linear correlation between LIBS and ICP increased from R = 0.76 to R = 0.95. An average error of 15% found in cross-validation of LIBS quantification appeared feasible for P quantification in fertilizers. Two reference samples with different matrix compositions were also analyzed, and the absolute error in the quantification was below 5%. Further, no significant fluctuation was found in P quantification when LIBS was performed over 150 days. |
