    Abstract:

    Received: 2018-01-30 | Accepted: 2018-02-26 | Available online: 2018-03-31 https://doi.org/10.15414/afz.2018.21.01.20-23 Aim of this experiment was to determine the gross energy concentration of fresh, wilted and ensiled hybrid of Rumex patientia L. x Rumex tianschanicus A. Los. (Rumex OK 2). Samples were collected in autumn months of the year 2017. The plant of Rumex OK 2 consist during autumn months only from rosette of leaves. The height of leaves was in autumn months following, September 56.68±13.80 cm; October 59.29±11.93 cm and November 55.98±10.80 cm. Rumex OK 2 silage was made from wilted matter, with or without of addition of dried molasses. Gross energy was determined as the heat released after combustion of a sample (Leco AC 500) in MJ per kilogram of dry matter of the sample. By the autumn months the concentration of dry matter, as well as the concentration of gross energy increased, except Rumex OK 2 silage from November. The highest concentration of gross energy had wilted Rumex OK 2 from November (18.02 MJ.kg -1 of dry matter). There was no significant effect of addition of dried molasses to wilted Rumex OK 2 before ensiling on gross energy concentration in Rumex OK 2 silages (P>0.05). Gross energy concentration of all types of analysed samples had relative high value (16.98 to 18.02 MJ.kg -1 of dry matter). Fresh or ensiled Rumex OK 2 can be used as a part of feed ratio for ruminants or can be utilised in biogas station. However, due to the low content of dry mater in fresh or wilted material the production of silage can be in autumn months problematic.

    Abstract:

    Article Details: Received: 2018-05-26 | Accepted: 2018-06-26 | Available online: 2018-06-30 https://doi.org/10.15414/afz.2018.21.02.60-62 Aim of this study was to determine the gross energy concentration of fresh, wilted and ensiled Rumex OK 2 ( Rumex patientia L. x Rumex tianschanicus A.Los.) from spring months and June. Samples were collected in spring months and June of the year 2018. The plant of Rumex OK 2 consist in March mainly from rosette of leaves and the stalk is not higher than leaves, from April is stalk higher than rosette of leaves. The height of Rumex OK 2 during analysed months was following, March 60.96 ± 5.22 cm; April 114.70 ± 35.15 cm, May 168.31 ± 39.74 cm and June 197.41 ± 48.44 cm. Rumex OK 2 silage was made from wilted matter, with or without of addition of dried molasses. Gross energy was determined as the heat released after combustion of a sample (Leco AC 500) in MJ per kilogram of dry matter (DM) of the sample. The dry matter and gross energy concentration of fresh Rumex OK 2 increased during study, dry matter from 7.42% in March to 56.97% in June and gross energy from 18.00 MJ.kg -1 of DM in March to 18.88 MJ.kg -1 of DM in June. Statistically significant (P 0.05). From all analysed Rumex OK 2 samples the highest concentration of gross energy had silage from May with addition of dried molasses, 19.04 MJ.kg -1 of DM. The utilisation of Rumex OK 2 from spring months can by neither for bioenergy production as a source of renewable energy, or after evaluation of nutritive value as a source of energy and nutrients in animal nutrition in form of pasture and silage. Rumex OK 2 from summer months seems to be utilized only as a source of heat via direct combustion.

    Article Details: Received: 2018-07-31 | Accepted: 2018-10-18 | Available online: 2018-10-31 https://doi.org/10.15414/afz.2018.21.04.197-200 The aim of this study was to determine the nutritive value of hybrid Rumex patientia L. x Rumex tianschanicus A.Los (Rumex OK 2). Rumex OK 2 can be considered as a technical or energetic plant for renewable production of biomass or as a feed as source of nutrients for animals. In this study two harvestings were planned, firs cut was realised in June (growth from March to June) and second cut was realised in November (growth from July to November). Samples of Rumex OK 2 plants were collected in the 20 th day of the month in March to June and in September to November. Concentration of nutrients were detected according to Regulation no. 2145/2004-100. Fresh Rumex OK 2 samples from March 7.42%, April 8.71% and September 4.89% had very low concentration of dry matter (DM). On the other hand samples from March, April, September and October had high concentration of crude protein in range from 31.42 to 24.54% of DM. From start of growth in spring to time of firs cut in June increased both concentration of dry matter from 7.42 to 56.62% and concentration of crude fibre from 14.86 to 47.38% of DM. Concentration of fat in Rumex OK 2 is low and similar to that of maize plant or alfalfa, whereas concentration of nitrogen free extract in Rumex OK 2 plant is similar only to alfalfa. Results of this article bring compact view over nutritional characteristic of Rumex OK 2, which can be according to gained results about nutritional value used as a source of nutrients in animal nutrition, or as a source of renewable biomass for bioenergy production.

  • Allantus luctifer (Hymenoptera: Tenthredinidae), a candidate agent for the biological control of Rumex spp.
    Entomological Research, 2008
    Co-Authors: Jinyoung Park, In-yong Lee, Jae-eup Park, Ohseok Kwon
    Abstract:

    The dock plant (Rumex spp.) is one of the most problematic pasture weeds worldwide. Allantus luctifer was selected as a potential biological control agent for Rumex spp. Continuous rearing of A. luctifer was carried out from 2005 to 2006, and its general biology is presented in this report. The preliminary host specificity test showed a promising result for using A. luctifer to control Rumex spp.

  • the potential of gastrophysa viridula as a biological control agent for Rumex obtusifolius
    The Korean Journal of Ecology, 2000
    Co-Authors: Ohseok Kwon
    Abstract:

    This study was carried out to see whether Gastrophysa viridula (Degeer) (Coleoptera : Chrysomelidae) could be used as a biological control agent for Rumex obtusifolius L., with human manipulation of the beetle population. The study was consisted of three experimental sets : Wet-Dry experiment (the wet weight Vs dry weight relationship of Rumex obtusifolius L.), Greenhouse feeding experiment, and Field experiment. There was a significant correlation between the total wet and dry weight of Rumex obtusifolius as follows : Total dry weight : -0.23542+ (0.17514Total wet weight) (=0.9317, p=0.047, T=16.927 (dF=21)). In the Greenhouse feeding experiment, the result was very promising. The relationship between the density unit of the beetles and the growth of the plant is given below (20 day) : Plant growth =105.8+(-34.4Density unit) (=0.76, p=0.13). A repeated introduction of the beetle population into the field vegetation of R. obtusifolius from April to October is suggested to see the beetle's grazing ability on the plant. This study shows that the potential grazing power of the beetle on Rumex obtusifolius was enough to defoliate the plants, but it was able to recover from its root reserves. The practical question remains as to whether repeated additions (by man) of the beetles to Rumex obtusifolius could eliminate them.

  • hybridization between alien species Rumex obtusifolius and closely related native vulnerable species r longifolius in a mountain tourist destination
    Scientific Reports, 2015
    Co-Authors: Koichi Takahashi, Masaaki Hanyu
    Abstract:

    Alien species expand their distribution by transportation network development. Hybridization between alien species Rumex obtusifolius and closely related native vulnerable species R. longifolius was examined in a mountain tourist destination in central Japan. The three taxa were morphologically identified in the field. Stem height and leaf area were greater in R. longifolius than R. obtusifolius; hybrids were intermediate between the two Rumex species. R. longifolius and the hybrids grew mainly in wet land and the river tributary; R. obtusifolius grew mainly at the roadside and in meadows. Hybrid germination rates of pollen and seeds were much lower than for the two Rumex species. Clustering analysis showed the three taxa each formed a cluster. Most hybrids were F1 generation; the possibility was low of introgression into the two Rumex species by backcross. This study clarified that (1) hybridization occurred between R. obtusifolius and R. longifolius because they occurred together in a small area, but grew in different water habitat conditions, and (2) hybridization was mostly F1 generation because hybrid pollen and seed fertility was low. However, we need caution about introgression into R. longifolius by R. obtusifolius in this area because of the slight possibility of F2 generation and backcrosses.

  • the evolution of reproductive systems and sex determining mechanisms within Rumex polygonaceae inferred from nuclear and chloroplastidial sequence data
    Molecular Biology and Evolution, 2005
    Co-Authors: Rafael Navajasperez, Rafael Lozano, Roberto De La Herrán, Carmelo Ruiz Rejón, Manuel Ruiz Rejón, Gines Lopez Gonzalez, M Jamilena, Manuel A Garridoramos
    Abstract:

    The genus Rumex includes hermaphroditic, polygamous, gynodioecious, monoecious, and dioecious species, with the dioecious species being represented by different sex-determining mechanisms and sex-chromosome systems. Therefore, this genus represents an exceptional case study to test several hypotheses concerning the evolution of both mating systems and the genetic control of sex determination in plants. Here, we compare nuclear intergenic transcribed spacers and chloroplast intergenic sequences of 31 species of Rumex. Our phylogenetic analysis supports a systematic classification of the genus, which differs from that currently accepted. In contrast to the current view, this new phylogeny suggests a common origin for all Eurasian and American dioecious species of Rumex, with gynodioecy as an intermediate state on the way to dioecy. Our results support the contention that sex determination based on the balance between the number of X chromosomes and the number of autosomes (X/A balance) has evolved secondarily from male-determining Y mechanisms and that multiple sex-chromosome systems, XX/XY 1 Y 2 , were derived twice from an XX/XY system. The resulting phylogeny is consistent with a classification of Rumex species according to their basic chromosome number, implying that the evolution of Rumex species might have followed a process of chromosomal reduction from x = 10 toward x = 7 through intermediate stages (x = 9 and x = 8).
