The impact of the volume of sugar cane on the wages of workers in the sugarcane refinery, ketol district, Aceh central regency

Sugarcane (Saccharum Offcinarum L) is one of the important commodities for making sugar which has become a necessity for industry and households. Sugarcane which is processed into sugar granules or often known as brown sugar is located in the Ketol District, Central Aceh Regency. Central Aceh Regency, especially in Ketol District, West Blang Mancung Village, is one of the sugar cane producers. Sugarcane is an annual plant that has its own characteristics, because in the stem there is sugar, sugarcane plants belong to the grass family (Gramenia) such as rice, corn and others. Linear regression analysis is an indirect approach that is used to measure the effect of the volume of sugarcane juice on the wages of workers in the sugar mill Sulaiman Ali sugarcane mill, Ketol District, Central Aceh Regency. The results of the linear regression analysis obtained from the research results are the equation = 7179,497 + 14,464 X1. Where it means that every increase in the total volume of sugarcane juice by 14,464 will increase the wage income of milling workers at the Sulaiman Ali sugarcane refinery, Ketol District, Central Aceh Regency, amounting to Rp. 14,464 /person with an average income of Rp. Rp 34,656.25/person/one production process.

Corn (Zea mays) as a Nutrient Source and Diet: A Review

Maize is also known as corn; it is a cereal. It is a member of Poaceae family which is a grass family. Maize originated 55 to 70 million year ago in central America. By seeing phylogenetic tree of grass species related to maize, it can be conclude that there is no direct ancestor of maize. The closest ancestor of maize are teosintes. Maize contains many phytochemical-like phystosterols, carotenoids and many other phenolic compounds. Maize also helps while reliving anti-HIV activity; this takes place due to the presence of Galanthus Nivalis Agglutinin (GNA) lectin. Maize is the great source of essential fatty assets. The maize cob and the root leaves of it are used to treat problem related to bladder, Nausea, vomiting. The endosperm of maize contains an alcohol solution prolamine called Zein, Which has a great role in pharmaceutical industry. Maize also contains resistant starch which reduces cancer-cecal, atherosclerosis and obesity related issues.

Spring barley varieties and perspective ranges laboratory screening against artificially created salinity stress backgrounds

The results of salinity resistance assessment of 5 spring barley ranges (Hordeum vulgare L.) Grass family (Poaceae) - Yaromir, Nadezhny, Znatny, Zlatoyar, and 9 types of own plant-breeding lines which are supposed to be perspective for the future use are given in this article. NaCl impact in the concentration of 0.7 and 0.9 mPa (0.98 and 1.26% NaCl) on seed germination and morphological indicators such as length and quantity of roots, length of seedlings were studied. The salinity stress resulted in the inhibitions of the roots length and seedlings in the provocative background if to compare with the control group background samples. At the concentration of 0.7 mPa salinity resistance value varied from 62.4 to 96.6% which corresponds to 1-2 salinity resistance groups. At the concentration of 0.9 mPa salinity resistance varied from 27.9 to 80.8% which corresponds to 1-3 salinity resistance groups. The yield capacity and adaptive qualities were examined on the initial data basis. Thus, there was a correlation dependence at both of sodium chloride concentrations revealed between the yield capacity of the field experience samples and the laboratory test samples.

A Null Allele of the Pol IV Second Subunit is Viable in Oryza sativa

All eukaryotes possess three DNA-dependent RNA polymerases, Pols I-III, while land plants possess two additional polymerases, Pol IV and Pol V. Derived through duplication of Pol II subunits, Pol IV produces 24-nt siRNAs that interact with Pol V transcripts to target de novo DNA methylation and silence transcription of transposons. Members of the grass family encode additional duplicated subunits of Pol IV and V, raising questions regarding the function of each paralog. In this study, we identify a null allele of the putative Pol IV second subunit, NRPD2, and demonstrate that NRPD2 is the sole subunit functioning with NRPD1 in small RNA production and CHH methylation in leaves. Homozygous nrpd2 mutants have neither gametophytic defects, nor embryo lethality, although adult plants are dwarf and sterile.

Self-assembly of Eucalyptus gunnii wax tubules and pure ß-diketone on HOPG and glass

Eucalyptus trees and many plants from the grass family (Poaceae) and the heather family (Ericaceae) have a protective multifunctional wax coating on their surfaces made of branched ß-diketone tubules. ß-diketone tubules have a different size, shape, and chemical composition than the well-described nonacosanol tubules of the superhydrophobic leaves of lotus (Nelumbo nucifera). Until now the formation process of ß-diketone tubules is unknown. In this study, extracted wax of E. gunnii leaves and pure ß-diketone were recrystallized on two different artificial materials and analyzed by scanning electron microscopy (SEM) and atomic force microscopy (AFM) to study their formation process. Both the wax mixture and pure ß-diketone formed tubules similar to those on E. gunnii leaves. Deviating platelet-shaped and layered structures not found on leaves were also formed, especially on areas with high mass accumulation. High-resolution AFM images of recrystallized ß-diketone tubules are presented for the first time. The data showed that ß-diketone tubules are formed by self-assembly and confirmed that ß-diketone is the shape-determining component for this type of tubules.

Spermine mediated improvements on stomatal features, growth, grain filling and yield of rice under differing water availability

Rice which belongs to the grass family is vulnerable to water stress. As water resources get limited, the productivity of rice is affected especially in granaries located at drought prone areas. It would be even worse in granaries located in drought prone areas such as KADA that receives the lowest rainfall in Malaysia. Spermine (SPM), a polyamine compound that is found ubiquitiosly in plants is involved in adaptation of biotic and abiotic stresses. The effect of SPM on growth,grain filling and yield of rice at three main granaries namely, IADA BLS, MADA and KADA representing unlimited water, limited water and water stress conditions respectively, were tested during the main season. Additinally, the growth enhancer was also tested during off season at KADA. Spermine increased plant height, number of tillers per hill and chlorophyll content in all three granaries. Application of SPM improved yield by 38, 29 and 20% in MADA, KADA and IADA BLS, respectively. Harvest index showed 2.6, 6 and 16% increases at IADA BLS, KADA and MADA, respectively in SPM treated plants as compared to untreated. Except for KADA which showed a reduction in yield at 2.54 tha−1, SPM improved yield at MADA, 7.21 tha−1 and IADA BLS, 9.13 tha−1 as compared to the average yield at these respective granaries. In the second trial, SPM increased the yield to 7.0 and 6.4 tha−1 during main and off seasons, respectively, indicating that it was significantly higher than control and the average yield reported by KADA. The yield of SPM treatments improved by 25 and 33% with an increment of farmer’s income at main and off seasons, respectively. Stomatal width was significantly higher than control at 11.89 µm. In conclusion, irrespective of the tested granaries and rice variety, spermine mediated plots displayed increment in grain yield.

Synergistic Effect of Methyl Jasmonate and Abscisic Acid Co-Treatment on Avenanthramide Production in Germinating Oats

The oat (Avena sativa L.) is a grain of the Poaceae grass family and contains many powerful anti-oxidants, including avenanthramides as phenolic alkaloids with anti-inflammatory, anti-oxidant, anti-itch, anti-irritant, and anti-atherogenic activities. Here, the treatment of germinating oats with methyl jasmonate (MeJA) or abscisic acid (ABA) resulted in 2.5-fold (582.9 mg/kg FW) and 2.8-fold (642.9 mg/kg FW) increase in avenanthramide content, respectively, relative to untreated controls (232.6 mg/kg FW). Moreover, MeJA and ABA co-treatment synergistically increased avenanthramide production in germinating oats to 1505 mg/kg FW. Individual or combined MeJA and ABA treatment increased the expression of genes encoding key catalytic enzymes in the avenanthramide-biosynthesis pathway, including hydroxycinnamoyl-CoA:hydrocyanthranilate N-hydroxycinnamoyl transferase (HHT). Further analyses showed that six AsHHT genes were effectively upregulated by MeJA or ABA treatment, especially AsHHT4 for MeJA and AsHHT5 for ABA, thereby enhancing the production of all three avenanthramides in germinating oats. Specifically, AsHHT5 exhibited the highest expression following MeJA and ABA co-treatment, indicating that AsHHT5 played a more crucial role in avenanthramide biosynthesis in response to MeJA and ABA co-treatment of germinating oats. These findings suggest that elicitor-mediated metabolite farming using MeJA and ABA could be a valuable method for avenanthramide production in germinating oats.

Cereal Grains of Bangladesh – Present Status, Constraints and Prospects

The edible seeds or grains of the grass family Poaceae (conserved name Gramineae) is commonly known as cereals and are cultivated for the edible component, grain consisting of the germ (or an embryo), endosperm and bran. Bangladesh, predominantly an agrarian country, has a long tradition of cereal grains cultivation, consumption and conservation. Rice is the staple food for millions (of people) across the globe including Bangladesh. It occupies more than 96% of the land area under “Cereal Agriculture” in Bangladesh. Maize occupies the 2nd position both in acreage and production followed by wheat and other minor cereals viz. barley, sorghum and millets. In this chapter, the historical development and production scenario of different cereal crops and their present status, constraints, challenges and opportunities has been described and discussed. The information presented here would provide a clear inside of the “Cereal Agriculture of Bangladesh” to students, researchers, administrators, policymakers, and the common people as well.

Molecular Control of Carpel Development in the Grass Family

Carpel is the ovule-bearing female reproductive organ of flowering plants and is required to ensure its protection, an efficient fertilization, and the development of diversified types of fruits, thereby it is a vital element of most food crops. The origin and morphological changes of the carpel are key to the evolution and adaption of angiosperms. Progresses have been made in elucidating the developmental mechanisms of carpel establishment in the model eudicot plant Arabidopsis thaliana, while little and fragmentary information is known in grasses, a family that includes many important crops such as rice (Oryza sativa), maize (Zea mays), barley (Hordeum vulgare), and wheat (Triticum aestivum). Here, we highlight recent advances in understanding the mechanisms underlying potential pathways of carpel development in grasses, including carpel identity determination, morphogenesis, and floral meristem determinacy. The known role of transcription factors, hormones, and miRNAs during grass carpel formation is summarized and compared with the extensively studied eudicot model plant Arabidopsis. The genetic and molecular aspects of carpel development that are conserved or diverged between grasses and eudicots are therefore discussed.
