univariate and multivariate data analysis methods

O experimento foi instalado em um delineamento inteiramente casualizado em esquema de parcela subdividida no espaço, com 15 repetições. Microestacas de plântulas de dez genótipos previamente cultivadas in vitro, com aproximadamente 1 cm, foram inoculadas em tubos de ensaio com 20 mL do meio de cultura WPM suplementado com 25 g L -1 de sacarose, solidificado com 7 g L -1 de ágar e pH ajustado em 5,8, e mantidas em três ambientes de cultivo por 180 dias. O estudo utilizou ferramentas estatísticas multivariadas a fim de melhorar a eficiência na análise dos resultados. Multivariate analysis of variance partial correlation principal component analysis germplasm Citrus sppĮste estudo teve por objetivo avaliar a influência do ambiente de cultivo para a conservação in vitro de genótipos de citros oriundos do Banco Ativo de Germoplasma da Embrapa Mandioca e Fruticultura. The results indicate that the principal component analysis is an effective tool in studying the behavior of different genotypes conserved under different in vitro growing conditionsThe growing conditions of 22☑☌, a light intensity of 10 μmol m -2.s -1 and a 12 hours photoperiod was the most adequate for reducing the growth of in vitro conserved plants, increasing the subculture time interval while keeping the plants healthy. The experiment was carried out in a completely randomized design in a split-plot in the space, with 15 replications. Approximately 1-cm of length microcuttings from plantlets derived from ten genotypes previously cultured in vitro were inoculated in test tubes containing 20 mL of WPM culture medium supplemented with 25 g L -1 sucrose, solidified with 7 g L -1 agar and adjusted to a pH of 5.8, and maintained under three environmental conditions for 180 days. The study used multivariate statistic tools in order to improve the efficiency in the analysis of the results. This study aimed to evaluate the influence of the growing environment on the in vitro conservation of citrus genotypes obtained from the Active Citrus Germplasm Bank of Embrapa Cassava and Fruit.
