TL;DR: The results imply that plant morphology influences small-scale invertebrate distribution, partly supporting the hypothesis that structurally complex plants harbour higher invertebrates abundance and invertebrate taxon richness.
Abstract: Habitat structure influences organism communities by mediating interactions between individuals and species, affecting abundance and species richness. We examined whether variations in the morphology of soft-bottom plants affect their function as habitat and whether complex structured plants support higher macroinvertebrate abundance and species richness. Three Baltic Sea plant species were studied, together with artificial plants resembling each species. In a field collection, we found higher invertebrate abundance on the morphologically more complex plants Myriophyllum spicatum and Chara baltica than on the structurally simpler plant Potamogeton perfoliatus. In a colonization experiment, we found the highest invertebrate abundance on artificial M. spicatum but found no difference between natural plants. Invertebrate taxon richness displayed no consistent relationship with plant structural complexity. The results imply that plant morphology influences small-scale invertebrate distribution, partly supporting the hypothesis that structurally complex plants harbour higher invertebrate abundance.

TL;DR: The occurrence of different chromosome numbers within almost all investigated plants led to the conclusion that aneusomaty is a rule in Poa pratensis.
Abstract: In a collection of Poa pratensis the variation in chromosome number and the relation between chromosome number and plant characters were studied. The material was collected at different places in the Netherlands. The number of chromosomes in the population varied from 33 to 92. Plants with 56, 63, 70 and 77 chromosomes were in the majority. The occurrence of different chromosome numbers within almost all investigated plants led to the conclusion that aneusomaty is a rule in Poa pratensis. In the progeny of some plants chromosome numbers were found which were considerably higher than those in the mother plants. It was assumed that this rise in chromosome number was caused by fertilization of aposporous egg cells. No relation could be found between chromosome number and plant characters. A hemiploid plant (39 chromosomes) was marked off from its sibs (77 chromosomes) by a stunted growth and pale leaf colour.

TL;DR: The study provided a clear diagnostic key for the classification showing the species-specific plant form attributable to unique leaves, branch type, plant height, flower size, and flowering habits of Chrysanthemum species.

TL;DR: This evaluation has helped to identify cultivar with specific yield and vegetative growth features and among all the seven accession evaluated accession JC007 is found to be promising which could be taken as productive genotype for commercial exploitation.
