Tolerance to water stress and shade in the invasive Impatiens parviflora

Abstract: Premise of research. Invasive plants usually have growth and reproductive abilities that allow them to cope with new habitats and environments. The small balsam, Impatiens parviflora, is one of the most widespread annual invasive species in Europe. As no precise physiological assessment for this species has been performed, we compared physiological traits linked to growth performance in contrasting environments.Methodology. Plants were cultivated in growth chambers under four different treatments varying by light and water conditions. We assessed the impact of water stress and low light levels on traits related to plant growth, leaf physiology, photosynthesis, and water status.Pivotal results. Tolerance of low light level was reflected by several morphological and physiological characteristics. The number of leaves initiated was not affected by light condition, whereas specific leaf area increased for plants grown under low light. In addition, the chlorophyll fluorescence parameters revealed that low ligh...

Effects of intrapopulation competition on morphological and agronomic characters of Jute plant ( Corchorus olitorius L.)

Abstract: The effects of population density on some agronomic traits of Corchorus olitorius were investigated by growing the seedlings in a field experiment at densities of 1, 2, 5, 10, 25, 50 and 100 plants per m2 during the raining season of 2006, at the Ojo campus of Lagos State University (LASU), Nigeria The randomized block design (RBD) was the experimental design used, with three replicates The direct effect of competition was investigated on the following agronomic attributes; final height/plant, number of branches/plant, stem girth/plant, number of leaves/plant, total fresh weight, total dry weight, moisture content, total leaf length, leaf petiole length, leaf area, blade length and blade width A highly significant effect (p occurrence of intraspecific competition in population of jute plant

Production of tetraploid plants of Trollius chinensis Bunge induced by colchicine.

Abstract: Zhang Q., Zhang F., Li B., Zhang L., Shi H. (2016): Production of tetraploid plants of Trollius chinensis Bunge induced by colchicine. Czech J. Genet. Plant Breed., 52: 34–38. Trollius chinensis Bunge is one of the important ornamental and medicinal plants cultivated in China. In this study, the tetraploid plants of Trollius chinensis were successfully induced by colchicine and their morphological, cytological and fertility characteristics were investigated. The results indicated that the tetraploid species of Trollius chinensis (2n = 4x = 32) was efficiently induced from the diploid species (2 n = 2x = 16) by colchicine under 0.05% to 0.2% concentrations, with the best induction under treatment combinations of 0.1%, 24h dura tion and 0.2%, 12h duration. In comparison with the diploid plants, the tetraploid plants exhibited dramatically varied phenotypic features, showing increased leaf length and width, petiole, flower and pollen diameters. In addition, they also exhibited increased stomatal size and chloroplast numbers in guard cells. Tetraploidy reduced the pollen fertility. Nevertheless, the maintenance of female fertility makes the tetraploid a potential germplasm for further polyploid breeding. Our investigation provides a potential design for an effective pathway to generate varieties of this plant species with chromosome doubling.
