TL;DR: It is concluded that the ‘Paluma’ guava tree is a plant with high “productive efficiency” compared with others species.
Abstract: In order to characterize morphophysiological aspects of guava tree ‘Paluma’, all the leaves of a quadrant of the canopy were collected from three plants representative of a commercial orchard (spaced: 7x5m). At the end of the harvest period, the number of leaves and the leaf area of the quadrant, the diameter of the canopy and the productivity of the orchard were determined. These data were used to estimate mean leaf area (LA), total plant leaf area (PLA), total number of leaves per plant (NLP), leaf area index (LAI), and plant “productive efficiency” (fruit production per plant/PLA). PLA was 151.2m2, LA 40.9cm 2 , LAI 6.7, productivity 323.7kg per plant, and “productive efficiency” of 0.467 and 3.054m 2 leaf area were necessary to produce 1kg fruit on a fresh and dry base, respectively. We may conclude that the ‘Paluma’ guava tree is a plant with high “productive efficiency” compared with others species

TL;DR: Variability of decorative morphological characters in plants collected from the spontaneous flora has indicated the possible use in selection programs.
Abstract: Spontaneous vegetation provides unlimited possibilities for the selection of valuable individuals from ornamental point of view. Field poppy (Papaver rhoeas), herb and dried fruit have decorative potential. The present work aimed variability of decorative morphological characters in plants collected from the spontaneous flora. Variability was studied using the percentage distribution and coefficient of variability. The limits of variation were high for number of capsules per plant (16-125), followed by the number of branches per plant (4-23). Coefficient of variability ranged from 10.12% to 50.9% for plant height number of capsules per plant. Existence of variability in the genetic material studied has indicated the possible use in selection programs.

TL;DR: The study was aimed to explore the effects of seed treatment with phosphemidum on chlorophyll content and morphometric parameters of flax seedlings and plants and found that samples were found to differ in the dynamics ofchlorophyll accumulation by the stages of ontogenesis.
Abstract: Genetic diversity of plants increases the possibility of choice and provides higher adaptability of plants to adverse environmental conditions. Flax (Linum usitatissimum L.) is one of the crops requiring attention and introduction in agricultural production. In Siberia, Russia already in 1908 the first experiments with flax were started in Tobolsk province. In the 20th century this branch was developed on the farms of Tyumen region. Heat resources, agrochemical properties of soils, water supply are adequate for the cultivation of this crop in the northern latitudes. The study was aimed to explore the effects of seed treatment with phosphemidum on chlorophyll content and morphometric parameters of flax seedlings and plants. Seventeen samples of fibre flax and three samples of linseed of different origin (Russia, Belarus, Ukraine, Canada, Czech Republic, France and Germany) from the collection of the Institute of Biology of Tyumen State University were studied. Air-dried seeds were treated with the solution of chemical agent phosphemidum in concentrations of 0.005, 0.01 and 0.1 %. Laboratory experiments revealed differences in morphometric parameters of plant seedlings. The response to seed treatment with mutagen was studied by the variability of chlorophyll content in the leaves. The samples were found to differ in the dynamics of chlorophyll accumulation by the stages of ontogenesis. All samples reacted to the increase of phosphemidum concentration by the decrease in chlorophyll content in leaves.

TL;DR: Anthers of sweet pepper F1 cultivar ‘Special’ were cultured on Dumas De Vaulx (C medium) and characterized their cytological and morphological characters, and SP55, SP62, SP68, SP72 and SP77 are found high yielding double haploids with high total soluble content and desirable fruit shape.
Abstract: Anthers of sweet pepper F1 cultivar ‘Special’ were cultured on Dumas De Vaulx (C medium), supplemented with 0.1mgL 2, 4-D and 0.1 mg · L kinetin with 3% sucrose, and 0.32% phytagel. The calluses obtained were further sub-cultured on Murashige and Skoog (MS) medium without growth regulators for regeneration. Regenerated plantlets were grown in plastic pots under plastic house and characterized their cytological and morphological characters in spring, 2008. Twenty percent plantlets were identified as haploid plants after chromosome and ploidy analysis. Haploid plants contained 12 chromosomes, high stomatal density with small stomatal length as compared to diploid plants. Stomatal length in haploids was 23.3% smaller than diploids. Haploid plants were characterized as small leaf and petiole size, poor vigor, thin stem and short plant height, short internodes and small flower buds, fruit size and fruit weight as compared to diploid plants and most of the haploid fruits were seedless. SP55, SP62, SP68, SP72 and SP77 are found high yielding double haploids with high total soluble content (8.6, 8.7, 9.2, 9.1 and 9.8 oBrix, respectively) and desirable fruit shape, and recommended them to exploit as inbred lines for heterosis breeding.
