Flores, R.A.C., F.P. García, E.M.O. Sánchez, A.M.B. Miró and O.A.A. Sandoval, 2018. Physico-chemical characterization of agricultural residues as precursors for activated carbon preparation. Bulg. J. Agric. Sci., 24 (3): 427–436 Biomass is a promising alternative and renewable energy source that can be transformed into other value-added products such as activated carbon. In this research, barley husk, corn cob and Agave salmiana leaves were characterized to determine their chemical composition and morphology to evaluate their potentiality as precursors of activated carbons. Based on the main composition results obtained, the biomass samples have suitable chemical and physical characteristics to be considered as good precursors of activated carbons, such as carbon contents greater than 40%, ash content less than 10%, moisture content less than 30%, high volatile contents with values from 75 to 80% and a porous and fi brous morphology. The results indicate that the main compositions in the biomass were cellulose and lignin. The cellulose content was more than lignin (15-26%) for the residues selected. Specifi cally, α-cellulose contents with values from 52% to 79%, β-cellulose contents of 13-44%, γ-cellulose contents less than 11%, and holocellulose contents of 82-83% were determined. The thermal decomposition for the biomass samples proceeded with fi ve stages attributed to the evaporation of some volatile compounds (70-150°C), to the degradation of hemicellulose (180-230°C), to the cellulose volatilization (250-350°C), to the lignin decomposition (380-550°C), and to the degradation of complex polymers and inorganic salts, respectively. The stage corresponding to the cellulose decomposition showed rapid mass decreased in the three residues. This results show that the cellulose and lignin content is another important parameter to evaluate the pyrolysis characteristics of a good precursor of activated carbon.

TRENEVA, G., Y. MARKOVSKA, E. WOLFRAM and K. DANOVA, 2014. Effect of plant growth regulators on growth patterns and enzymatic antioxidant activities in Hypericum calycinum shoot cultures. Bulg. J. Agric. Sci., Supplement 1: 46–50 Hypericum calycinum L. (section Ascyreia) is a species of the Hypericum genus, relative to the medicinal plant H. perforatum (St. Jonn’s worth). Unlike the widely studied H. perforatum, it is characterized by the lack of hypericins production. However, research has revealed its commensurable antidepressant activity, as compared with the latter species, and shown the presence of polyphenolics with marked radical scavenging activity. In order to develop an in vitro system with the potential of a novel source of bioactive constituent’s characteristic for the Hypericum genus, we initiated in vitro cultures of H. calycinum. In the present work we studiy the effect of exogenous BA and IBA treatments on the developmental patterns, enzymatic and non-enzymatic antioxidant defence of hypericin non-producing Hypericum calycinum shoot cultures. It was shown that supplementation of PGR led to stimulation of phenylalanine ammonia-lyase and superoxide dismuthase, as well as non-enzymatic antioxidant glutathione. However, they inhibited glutathione reductase, as well as lowered the levels of fl avonoids, ascorbate and dehydroascorbate in comparison with plant growth regulators-free control. Further on, it was established that elevation of IBA concentration slightly stimulated axillary shoot formation and shoot length, but inhibited polyphenolic levels in vitro. These results are in agreement with our previous results of interrelations between biomass formation and polyphenolics production in other Hypericum species in vitro. An in vitro culture system optimization is in progress in order to increase biomass production and retain biosynthetic capacity of the species.

Sci., 16: 36-41 The objective of the current study is to test an SSR marker (Ol12FO2) associated with methylsulphinylalkyl glucosinolates and its potential application for marker assisted selection (MAS) in kale (Brassica oleracea var. acephala). Methylsulphinylalkyl glucosinolates such as glucoiberin and glucoraphanin are known to have health promoting properties and to protect against various forms of cancer. Markers associated with such important traits are important to expedite breeding programs aimed to select for desired traits for further use in generating improved novel lines. The findings of the present study revealed that successful amplifications with genomic DNA from kale genotypes were observed with the SSR marker Ol12FO2 and bands of expected sizes were obtained. It was determined that Ol12FO2 was polymorphic among kale genotypes. The results obtained in the present study demonstrated successful amplification of markers within different vegetable brassicas.

Sci., 15: 214-221 In the study, the heterosis percentages and combining ability effects were determined for heading time (HT), thousand kernels weight (TKW) and plant yield (PY) of 6 durum wheat parents and their 15 half-diallel crosses. Two local populations (Beyaziye and Bagacak) and four cultivars (Kunduru 1149, Cakmak-79, Diyarbakir-81 and Duraking) of durum wheats were used as parents in the study. Heterosis percentages for high-parent and midparent were - 2.16 % and - 0.74 % for heading date; - 1.64 % and 3.78 % for 1000 kernel weight; - 2.24 % and 5.24 % for plant yield, respectively. The highest heterosis percentage for mid-parent was determined at the hybrids of ‘Kunduru 1149 x Diyarbakir81’ (1.10 %) for heading date; ‘Kunduru 1149 x Cakmak 79’ (12.86 %) for 1000 kernel weight; ‘Beyaziye x Duraking’ (37.67 %) combination for plant yield. The general combining ability (GCA) and specific combining ability (SCA) components of variance were significant for three traits studied. The levels of heterosis and general and specific combining abilities of parental lines were sufficient to sustainable production of hybrid breeding and early selection of breeding lines.

The highest heterosis percentage for mid-parent was determined at the hybrids of ‘Kunduru 1149 x Diyarbakir81’ (1.10 %) for heading date; ‘Kunduru 1149 x Cakmak 79’ (12.86 %) for 1000 kernel weight; ‘Beyaziye x Duraking’ (37.67 %) combination for plant yield. The general combining ability (GCA) and specific combining ability (SCA) components of variance were significant for three traits studied. The levels of heterosis and general and specific combining abilities of parental lines were sufficient to sustainable production of hybrid breeding and early selection of breeding lines.","PeriodicalId":9299,"journal":{"name":"Bulgarian Journal of Agricultural Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70793268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
