Two sweet sorghum varieties (salt tolerant Jitianza 2 and salt sensitive Lvneng 1) were used to investigate their adaptation to NaCl stress under different cultivation conditions of potted cultivation and field cultivation, and selective transport capacity for K+ over Na+, and Ca2+ over Na+ of leaf sheath. NaCl stress decreased Pn, Fv/Fm, fresh weight of leaf sheath and leaf blade, field yield in both varieties. NaCl stress induced Na+ accumulation while it decreased K+ and Ca2+ levels in leaf sheath and leaf blade of both varieties. The increase in Na+ of leaf blade and the decrease in K+ and Ca2+ of leaf blade were greater in Lvneng 1 than those in Jitianza 2. Furthermore, the Na+, K+ contents in leaf sheath of Jitianza 2 were significantly higher than those of Lvneng 1 under NaCl stress. The selective transport capacity for K+ over Na+, and Ca2+ over Na+ of leaf sheath in Jitianza 2 was significantly greater than that in Lvneng 1. Pn, Fv/Fm, stem stalk field, ear field, juice yield, stalk Brix, sugar content of Jitianza 2 were significantly higher than those of Lvneng 1, which was correlated with stronger selective transport capacity for K+ over Na+, Ca2+ over Na+ of Leaf Sheath of Jitianza 2.

Abstract A description is provided for Phomopsis oryzae-sativae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Oryza saliva. DISEASE: Collar rot of rice, appearing at the end of tillering stage. Visible symptoms are small dark brown lesions at the base of the auricle of the topmost fully expanded leaf. These lesions enlarge to cover the whole auricle and in the advanced stage lesions extend to the adjacent parts of the leaf sheath and leaf blade. Within 14 days the blade joint at the top of leaf sheath turns dark brown and then rots, causing the leaf blade to drop off (Kanjanasoon, 1962). GEOGRAPHICAL DISTRIBUTION: Asia (Thailand). TRANSMISSION: No studies reported. Conidia presumably dispersed by water splash.

AbstractExperiments were made to study the proportion, chemical composition, and rumen degradability of the morphological components of barley straw (Corgi variety) and to study the selection of these components by sheep. The proportions in the harvested straw dry matter (DM) as leaf blade, leaf sheath, stem and chaff were 128, 314, 500 and 58 g/kg DM, respectively. The different components of straw on analysis proved to have very different concentrations of nitrogen and neutral-detergent cellulase digestibility. The leaf blades had the highest and the stems the lowest values. The degradabilities of DM in the components and in the whole straw were determined by measuring DM loss from samples incubated in nylon bags for various periods in the rumen of sheep. Responses were measured using the mathematical model p = a+b (1–e−ct) where p is DM loss, (a+b) potential degradability, c the rate constant of DM loss and t is the time of incubation. DM losses decreased in the order leaf blades > leaf sheath > whole plant > chaff > stems. Leaf blades also had the highest potential degradability and rate of degradation.In another trial, five sheep were offered unchopped barley straw ad libitum. There were five treatment periods in which sheep were allowed to leave uneaten proportionately 0·2, 0·3, 0·4, 0·5 and 0·7 of the straw on offer for assessing the animal's selection of the morphological components of that straw. The amount of leaf blade in the material consumed increased in largely a linear (P < 0·01) fashion with the amount of excess allowance. The proportion of stem eaten varied conversely. The selection of leaf sheath was less apparent. Little stem was consumed until the proportion of leaf blade in the food available decreased below proportionately 0·4. The practical significance of the study is discussed.

A total of 110 rice varieties of which 108 local (From Bangladesh Rice Research Institute) and two hybrid varieties (From ACI Ltd. Bangladesh) were used to identify the morphological traits during July, 2008 to June, 2009. These varieties represented four types viz. T. Aman (n=92), B. Aman (n=15), Boro (n=2) and Jhum accession (n=1) as described by Bangladesh Rice Research Institute’s literature. Though all these materials were varied ecotypically but grown in one (T. Aman) season. Irrespective of groups of all, 90 varieties were appeared distinctly morphologically from others due to seed colour; stigma colour; anthocyanin colouration of leaf sheath, nodes and lemma:palea, presence of awn and nodal root. Among 90 distinct varieties 19 were distinctly different from others by four traits, nine by three traits, 24 by two traits and 38 varieties by only single trait. The rest 20 varieties were distinguished flag leaf: attitude of the leaf blade. This was done to assess the quality traits of distinctness as major concern and was noninfluenced by the environment.

The fossil energy sources used in the world are gradually decreasing and limited. Fossil fuels cause environmental pollution, and the unit price is constantly increasing. For this reason, demand for cheaper and renewable energy sources that do not pollute the environment is increasing day by day. The sweet sorghum plant has attracted attention in recent years with its high biomass yield, sugar content and bioethanol yield. In this study, it was aimed to determine the bio-fuel potential of some sweet sorghum genotypes in semi-arid climatic conditions. The experiment was set up in randomized complete block design with 4 replicates. Research was carried out in 2015 under Harran Plain (36o 42’ N and 38o 58’ E) second crop conditions, Sanliurfa, Turkey. In the study 49 genotypes of sweet sorghum were used. Stalk yield, juice yield, syrup yield, brix, sugar yield and theoretical ethanol yield were determined in the study. Significant differences were found between the genotypes for tested characteristics (P≤0.01). Stalk yield ranged from 7110.0 kg da-1 to 24262.5 da-1, juice yield from 2550.0 L da-1 to 12187.5 L da-1, syrup yield from 291.4 L da-1 to 2242.5 L da-1. Also, brix value varied between %7.0 and %18.87, sugar yield between 247.7 da-1 and 1906.1 da-1, Theoretical ethanol yield between 131.9 L da-1 and 1014.8 L da-1. Considering to stalk yield, juice and syrup yield, brix, sugar yield and theoretical ethanol yield; Nebraska sugar, Topper 76, Smith, M81E and Corina genotypes were found as the best. As a result of research, 21 genotypes with better performance than the others were selected for further studies.

Sweet sorghum is one of the bioethanol producing plants that can be cultivated on dry land with a wide climate range. The study aims to utilize dry land forest areas for the development of several varieties of sweet sorghum as a bioethanol feedstock. The types used are Suri 3, Kawali, Super 2 and Suri 4 varieties which cultivated at various biofertilizer doses per plant, namely 5 g, 10 g, and 15 g. This experiments used Randomized Block Designed factorial followed by Duncan's Multiple Range Test. The results showed that the Suri 3, Kawali and Super 2 varieties had above-average agronomic and production characters with the highest values at stem height (301.28 cm), stem weight (145.21g), and seed dry weight (39.74 g) achieved by the variety of Super 2.  Varieties of Suri 3  has the highest potential the content of sugar in the stem (16.69%). Suri 4 variety produces the most volume of juice with the lowest of sugar content. The interaction of varieties  and biofertilizer doses was significantly different against the number of nodules, and the highest of nodules number accomplished by Super 2 varieties at a dose of 10 g (11.77).
