Grain Filling Stage

Based on the experiment of two inbred aromatic rice varieties and one hybrid aromatic rice line treated under four different temperatures( daymean temperature 21°C, 23°C, 26°C and 30°C respectively) during grain filling stage in phytotrons, the shape and arrangement of endosperm starch granules in rice grain transection were observed by scanning electron microscope and the related characteristics of rice grain qualities of chalky percent and chalkiness were analyzed at the same time. The results showed that under the lower temperature( daymean temperature21°C and 23°C), many large compound starch granules with clear angulars packed together regularly without significant natural gaps bewteen starch granules in the tansectional endosperm. However, with the increase of temperature, starch granules in the transectional endosperm were changed from regularly shaped and closely and orderly arranged to various shaped and chaoticly arranged with obvious natural gaps between starch granules, which was closely consistent with the poorer appearance quality under the higher temperature, which indicated that the endosperm structure is closely related with appearance quality of aromatic rice.

The Impact

Abstract In the newborn, penile length is determined by a number of androgen dependent and independent factors. The current literature suggests that there are inter-racial differences in stretched penile length in the newborn and although congenital micropenis should be defined as a stretched penile length of less than 2.5SDS of the mean for the corresponding population and gestation, a pragmatic approach would be to evaluate all boys with a stretched penile length below 2 cm, as congenital micropenis can be a marker for a wide range of endocrine conditions. However, it remains unclear as to whether the state of micropenis, itself, is associated with any long-term consequences. There is a lack of systematic studies comparing the impact of different therapeutic options on long-term outcomes, in terms of genital appearance, quality of life and sexual satisfaction. To date, research has been hampered by a small sample size and inclusion of a wide range of heterogeneous diagnoses; for these reasons, condition specific outcomes have been difficult to compare between studies. Lastly, there is a need for a greater collaborative effort in collecting standardized data so that all real-world or experimental interventions performed at an early age can be studied systematically into adulthood.

La cercosporiose due à Cercospora oryzae est un champignon pouvant causer des pertes allant jusqu'à 60%. Elle est de plus en plus fréquente en Afrique de l'Ouest. Les premières prospections réalisées au sud du Bénin ont indiqué que Cercospora oryzae a une contribution large puisqu’elle a affectée 85% des champs de riz des trois zones agroécologiques du sud Bénin. Cette étude vise principalement à contribuer à la connaissance détaillée des effets de Cercospora oryzae sur les grains afin d’optimiser la conservation, la commercialisation et la production. Elle a consistée a : i) évaluer les effets de Cercospora oryzae sur le pouvoir germinatif des grains, ii) évaluer les effets de Cercospora oryzae sur le développement de la ternissure. L’étude a combiné des outils physiologiques et phytiatriques. Au terme des travaux, les variétés testées ont enregistré une bonne teneur en eau pour un minimum de 6%, ainsi qu’un bon taux de germination. A la fin de l’étude nous avons pu constater que Cerocpora oryzae entrainait une baisse du pouvoir germinatif des grains, une altération de la graine blanche et une décoloration de l’enveloppe. Ces résultats constituent une étape d’un travail de recherche approfondi sur la caractérisation (agronomique et génétique) de Cercospora oryzae afin de proposer des méthodes de luttes. Mots clés : Pouvoir germinatif, décoloration, altération, Cercospora oryzae, riz.   English Title: Study of the effect of Cercospora oryzae Miyake on the quality of rice grains and the development of tarnishSigatoka caused by Cercospora oryzae is a fungus that can cause losses up to 60%. It is more and more frequent in West Africa. The first surveys carried out in the south of Benin indicated that Cercospora oryzae has a large contribution since affected 85% of the rice fields of the three agroecological zones of southern Benin. The main objective of this study is to contribute to detailed knowledge of the effects of Cercospora oryzae on grains in order to optimize conservation, marketing and production. It consisted in: i) evaluating the effects of Cercospora oryzae on the germination power of the grains, ii) evaluating the effects of Cercospora oryzae on the development of tarnish. The study combined physiological and phytiatric tools. At the end of the work, the varieties tested recorded a good water content for a minimum of 6%, as well as a good germination rate. At the end of the study we could see that Cerocpora oryzae did not cause a drop in the germinative power of the grains but rather resulted in an alteration of the white seed and a discoloration of the envelope. These results constitute a stage of an in-depth research work on the characterization (agronomic and genetic) of Cercospora oryzae in order to propose methods of struggle.Keywords: Germination, discoloration, deterioration, Cercospora oryzae, rice.

More than half the world's people consume rice every day and fulfills over 21% calorific requirement of world population. It is considered the whole grain which is rich in fiber and it contains 80 percent with protein, phosphorus, and potassium. There are hundreds of different varieties of rice and each rice grain has a unique shape, texture, and flavor that make it just right for certain dishes. The quality of rice between various types has different standards. Therefore, you must select the best quality rice because rice with best quality is not only good for consumption but also good for health. Analyzing grain sample manually is a tedious task and also time consuming. The paper presents the solution to analysis and grading of rice grains using image processing techniques. Image reduction, image enhancement, and image increment, object recognition in spatial domain is applied on grain by grain of different samples of rice to determine its size, color and quality as whole to grade the grain of rice. We find the endpoints of each grains and after we measure the length and breadth of rice grains.

Neste sentido, objetivou-se avaliar, com a realização do presente estudo, a qualidade industrial de grãos de dois cultivares de arroz irrigado em função de épocas de supressão da irrigação e graus de umidade à colheita. O experimento foi realizado nas safras 2011/12 e 2012/13 na área didático experimental de várzea da Universidade Federal de Santa Maria, Rio Grande do Sul. Os tratamentos foram compostos de: dois cultivares: o híbrido INOV CL e o cultivar Puitá INTA CL; quatro épocas de supressão da irrigação: 5, 15, 25 e 35 dias após a antese (DAA); e cinco graus de umidade média dos grãos na colheita: 24, 22, 20, 18 e 16%. O delineamento experimental foi de blocos ao acaso com quatro repetições por tratamento. O cultivar Puitá INTA CL apresenta superior qualidade em relação a grãos inteiros, vítreos, gessados e opacos ao híbrido INOV CL. A umidade adequada dos grãos à colheita para ambos cultivares ocorre no intervalo de 24 a 20%. A supressão de irrigação não interfere na qualidade de grãos inteiros, vítreos, opacos e gessados. Palavras-Chave: beneficiamento; grão inteiro; grão gessado; grão opaco; Oryza sativa L.  LONDERO, G.

L. 4INDUSTRIAL QUALITY OF RICE GRAINS ARISING FROM THE WITHHOLDING OF IRRIGATION AND HARVEST MOISTURE  2           ABSTRACT Quality of irrigated rice grains is critical for their marketing. In this context, the study aimed to evaluate the industrial quality of two irrigated rice cultivars as a function of two times of irrigation withholding,   and moisture content at harvest.  The experiment was conducted during the 2011/12 and 2012/13 seasons in the experimental floodplain of the Federal University of Santa Maria, Rio Grande do Sul state, Brazil. The treatments consisted of  two cultivars:   hybrid INOV CL and  Puitá INTA CL ; four irrigation withholding times:  5, 15, 25 and 35 days after anthesis (DAA); and five levels of mean grain moisture   at harvest; 24, 22, 20, 18 and 16 %. The experimental design was randomized blocks with four replicates per treatment.   The cv. Puitá INTA CL  presented higher quality concerning milling, translucency, opacity and chalky grains than the cv. hybrid INOV CL.  Suitable moisture content of grains at harvest for both cultivars is at the range of 24 to 20%.  Irrigation withholding did not affect milling quality, translucency, opacity and chalky grains. Keywords: Processing, milling quality, chalky grain, opacity, Oryza sativa.
