TLDR
In this article, an easy to implement cluster-based method for identifying groups of nonhomogeneous means is proposed, which overcomes the common problem of the classical multiple-comparison methods that leads to the construction of groups that often have substantial overlap.Abstract:
This article proposesan easy to implement cluster-based method for identifying groups of nonhom ogeneous means. The method overcomes the common problem of the classical multiple-comparison methods that lead to the construction of groups that often have substantial overlap. In addition, it solves the problem of other cluster-based methods that do not have a known level of significance and are not easy to apply. The new procedure is compared by simulation with a set of classical multiple-comparison methods and a cluster-based one. Results show that the new procedure compares quite favorably with those included in this article.read more

Effects of cyanobacterial extracellular products and gibberellic acid on salinity tolerance in Oryza sativa L
TL;DR: It is proposed that Scytonema hofmanni extracellular products may counteract altered hormone homeostasis of rice seedlings under salt stress by producing gibberellin-like plant growth regulators.

TL;DR: This is the first report combining independent variables, constructing a fingerprint including elemental composition, isotopic, and polyphenol patterns to differentiate wines, matching part of this fingerprint with the soil provenance.

From grape to wine: Changes in phenolic composition and its influence on antioxidant activity.
TL;DR: Multiple regression analysis showed a high correlation between phenolic composition and AC of samples, being anthocyanins the main family with significant contribution to AC.

Differences in ATP Generation Via Glycolysis and Oxidative Phosphorylation and Relationships with Sperm Motility in Mouse Species
TL;DR: It is found that the sperm of species with higher oxygen consumption/lactate excretion rate ratios were able to produce higher amounts of ATP, achieving higher swimming velocities and that sexual selection could promote adaptations in sperm energetic metabolism tending to increase the usage of a more efficient pathway for the generation of ATP.

Polyamine oxidase activity contributes to sustain maize leaf elongation under saline stress
Andrés Rodriguez,Santiago Javier Maiale,Ana Bernardina Menéndez,Ana Bernardina Menéndez,Oscar Adolfo Ruiz +4 more
TL;DR: It is demonstrated that, under salinity, polyamine oxidase activity provides a significant production of reactive oxygen species in the apoplast which contributes to 25-30% of the maize leaf blade elongation.

A Cluster Analysis Method for Grouping Means in the Analysis of Variance
A. J. Scott,M. Knott +1 more
TL;DR: In this paper, the authors used the techniques of cluster analysis to split the treatments into reasonably homogeneous groups and developed a likelihood ratio test for judging the significance of differences among the resulting groups.

An Evaluation of Ten Pairwise Multiple Comparison Procedures by Monte Carlo Methods
S. G. Carmer,M. R. Swanson +1 more
TL;DR: In this article, computer simulation techniques were used to study the Type I and Type III error rates and the correct decision rates for ten pairwise multiple comparison procedures, and the results indicated that Scheffe's test, Tukey's test and the Student-Newman-Keuls test are less appropriate than either the least significant difference with the restriction that the analysis of variance F value be significant at α =.05, two Bayesian modifications of the smallest significant difference, or Duncan's multiple range test.
