“…This means that some features of ISH, such as their distinct patterns of environmental resistance and vegetative growth (Gomes Junior et al, 2014), at least initially, they were not remarkable enough to express different nutritional relationships from African species, a fact that facilitates the application of DRIS in areas with these cultivars. Similarly, it was found, in cotton (Gossipium hirsutum) crops, that DRIS can be applied regardless of the cultivar used (Singh et al, 2012).…”

“…However, in addition to non-susceptibility to LY, ISH have distinct characteristics when compared to African palms, such as one third the speed of vertical stalk growth (0.20 m yr -1 ), tolerance to insect pests, and greater content of unsaturated oil . Moreover, they have tolerance to waterlogged soils and water stress (Gomes Junior et al, 2014), a low rate of natural pollination , and apparently higher nutritional requirements, especially for magnesium (Franzini et al, 2012) and boron.…”

ABSTRACT:The oil palm crop has expanded significantly in the state of Pará, which has not been followed in a proportional manner by studies aiming at increasing yield through plant nutrition. The objective of this study was to evaluate general and specific norms of the Diagnosis and Recommendation Integrated System (DRIS) for genetic materials of oil palm (African and interspecific hybrid) at two ages (young and adult plants) and evaluate possible deficiencies in fertilization and soil correction practices. The DRIS norms were composed of means, standard deviations, and coefficients of variation of bivariate, specific, and general relationships among nutrients of 144 leaf samples. The DRIS norms specific for genetic material did not differ from the general norms; however, a large number of differences were found between specific bivariate relationships for age groups, among themselves, and in relation to the general norms. The regression analysis between the nutritional balance index and yield were better explained when age groups were discriminated. In the young plants, the number of cases of stands with deficiencies followed the order Ca > Fe > B > S > Mn > K > Mg = Cu > Zn > N > P; and for adults, this order was Ca > Mn > Zn > Fe > S = B > N = Cu > K > Mg > P. The DRIS norms can be utilized in diagnostics regardless of genetic material; however, they must be specified for the age of the plant. Most of the stands showed deficiency in Ca and micronutrients, coinciding with the least used nutrients in oil palm crops in the state of Pará, as well as emphasizing the need for soil liming.

“…For the correlation between NB and MBW, negative, mean to high values were observed in the study of Okwuagwu et al (2008) (-0.22 and -0.37) as well as of Okoye et al (2009) (-0.57 , respectively (Table 3). In the evaluation of the first two years of production of the same population, Gomes Junior et al (2014) identified the progenies RUB 1210, RUB 1274, RUB 1199, and RUB 1232 as the most productive.…”

“…The total weight of bunches is the product of two other traits (number of bunches and mean bunch weight). The genetic parameters of the yield-related traits were estimated in different oil palm populations (Soh et al 2003, Cedillo et al 2008, Okwuagwu 2008, Okoye et al 2009), but information about HIE OxG populations is still scarce , Gomes Junior et al 2014). …”

-The objective of this work was to quantify the genetic divergence among accessions of white-type acai palm (Euterpe oleracea), through morpho-agronomic characters. The accessions belong to the active acai palm germplasm bank of Embrapa Amazônia Oriental. Thirteen characters were evaluated in 26 accessions, originated from six municipalities in the state of Pará, Brazil. The data were subjected to deviance and multivariate analyses, based on the average Euclidean distance, and were grouped by Tocher's method and the unweighted pair group method with arithmetic mean (UPGMA). The accessions differed for eight characters. The distances among accessions ranged from 0.64 to 2.62, with an average of 1.36, and four groups were formed by Tocher's method and two by the UPGMA. Seven major components explained 88.03% of the variation, whose graphic dispersion showed the tendency of forming four groups. The characters weight of 100 fruits, number of rachillae per bunch, and fruit yield per bunch contributed the most to the divergence, and the accessions from the municipalities of Breves, Curralinho, and Limoeiro do Ajuru were the most divergent. Therefore, the accessions of white acai palm show strong divergence and variability, which favor the selection of desirable individuals.
