In order to study the effect of cold stress in flowering stage on yield and yield components of different rice cultivars, an experiment was performed as split plot factorial based on completely randomized design (CRD) in greenhouse of deputy of rice research institute of Iran (Amol) in 2010, in three repetitions. Treatment included 5 varieties as main factors that included cultivars of shirudi, fajr, local tarom, hybrid, and line 843. Two levels of temperaturesT1(13°C, stress temperature) andT2(32°C, normal temperature, control) along with flowering stage were selected as two subfactors. Three seedlings were planted in each plot. The cold stress was done in flowering stage with holding pots at 13°C for 15 days. Results showed that low temperature had significant effect in level of 1 percent on all characters, such as the number of panicles, the length of panicle, and the number of full, empty, and total grains; as a result, yield had caused significant reduction. Interaction between temperature and varieties showed that most tolerant variety in relation to temperature stress along with least percentage yield (19%) is shirudi variety and the most sensitive one with most percentage of yield decrease (29%) was local tarom variety.

<p>The interest in using Jatropha curcas L. from the<br />family Euphorbiaceae for the production of biofuel is rapidly<br />growing. The research objective was to determine genetic<br />variation of several high yielding physic nuts based on their<br />morphology, agronomy, and isozyme characters. The<br />research used Completely Randomized Design with three<br />replications. The treatment was consisted of 8 genotypes i.e.<br />IP-1A, IP-1M, IP-2P, Lombok Timur, Lombok Tengah,<br />Lombok Barat, Sumbawa, and Bima. Analysis of isozyme of<br />the eight genotypes was also conducted according to 5<br />enzyme systems, i.e. peroksidase, esterase, aspartat<br />aminotransferase, malat dehidrogenase, and alcohol<br />dehidrogenase. Observation was done on qualitative and<br />quantitative characters as well as banding pattern derivedisozymes.<br />The results showed that genetic variation was low<br />when based on qualitative characters and isozyme (0-25%)<br />but relatively high when based on selected quantitative<br />characters analysis (17-81%). Analysis of combined<br />qualitative, quantitative, and isozyme characters still gave<br />low genetic variation (6-33%). Based on the quantitative<br />characters at similarity coefficient of 46% the genotypes can<br />be devided into three clusters. Improved population<br />genotypes, i.e. IP-1A, IP-1M, and IP-2P were placed in 3<br />different clusters, while other genotypes from NTB area<br />were grouped in the same cluster. Therefore, selection<br />among population of the same ecotype based on agronomic<br />characters such as yield components, yield and oil content<br />was suitable in Jatropha improvement, especially when<br />genetic variation was low. Furthermore, introduction,<br />mutation and crossing are suggested to increase genetic<br />variation of current Jatropha collection.</p>

Egg is a nutrient dense food, however the cylical egg glut characterized by egg spoilage, quality deterioration and wastage imparts negatively on poultry farmers. Powdered dried egg provides a convenient alternative to this problem. The focus of this study was to compare and evaluate differently processed whole eggs into powder egg. An experiment was conducted to evaluate the potential of whole egg powders made from different processing methods. The yield, proximate composition, microbiological load from differently processed (Spray dried- commercial, Freeze dried and Dehydrated) whole egg powders were compared. The treatments in this experiment were the Spray Dried, Freeze Dried and Dehydrator Dried Whole Egg Powders represented as SDWEP, FDWEP and DDWEP, respectively. Thirty-five eggs each were used to produce the FDWEP and DDWEP while the SDWEP was obtained from United State of America. The Experimental design was a completely randomized design. Powder percentage yield of 1000g raw eggs (26.7%) and crude protein (52.78%) was highest (P<0.05) from SDWEP. Salmonella spp observed in raw eggs was destroyed by heat from the processing methods in the whole egg powders. The microbial load was within the 2cfu/g acceptable limits. This study concludes that whole egg powders produced by spray, freeze or dehydrator methods are generally accepted and serve as good alternatives to fresh eggs in addition to their use in the confectionary industry not compromising the final product quality.     L'œuf est un aliment riche en nutriments, mais la surabondance d'œufs cyclique caractérisée par la détérioration des œufs, la détérioration de la qualité et le gaspillage affecte négativement les éleveurs de volaille. L'œuf séché en poudre offre une alternative pratique à ce problème. L'objectif de cette étude était de comparer et d'évaluer des œufs entiers transformés différemment en œufs en poudre. Une expérience a été menée pour évaluer le potentiel des poudres d'œufs entiers fabriquées à partir de différentes méthodes de traitement. Le rendement, la composition approximative, la charge microbiologique de poudres d'œufs entiers traitées différemment (séchées par pulvérisation-commerciales, lyophilisées et déshydratées) ont été comparées. Les traitements dans cette expérience étaient les poudres d'œufs entiers séchés par pulvérisation, lyophilisés et séchés au dés hydrateur représentés respectivement par SDWEP, FDWEP et DDWEP. Trente-cinq œufs chacun ont été utilisés pour produire le FDWEP et le DDWEP tandis que le SDWEP a été obtenu des États-Unis d'Amérique. Le plan expérimental était un plan complètement randomisé. Le pourcentage de rendement en poudre de 1000 g d'œufs crus (26,7 %) et de protéines brutes (52,78%) était le plus élevé (P< 0,05) du SDWEP. Salmonella spp observée dans les œufs crus a été détruite par la chaleur des méthodes de traitement dans les poudres d'œufs entiers. La charge microbienne était dans les limites acceptables de 2 cfu/g. Cette étude conclut que les poudres d'œufs entiers produites par pulvérisation, congélation ou déshydratation sont généralement acceptées et constituent de bonnes alternatives aux œufs frais en plus de leur utilisation dans l'industrie de la confiserie sans compromettre la qualité du produit final.

Set Up

A greenhouse pot experiment was conducted in the Agricultural University of Athens in order to evaluate the effect of several greenhouse cover materials on the performance and yield of hemp. The experiment was set up in a completely randomized design (CRD) with five treatments/greenhouses (G1, G2, G3, G4/Control, and G5). Measurements included plant height, PAR (Photosynthetic Active Radiation), chlorophyll content, solar irradiance, soil and leaf temperature, and yield components (the number of buds, their weight, length, and compact index, CBD content, and CBD yield per plant). The results of the present study suggest that the different polyethylene cover films alter the environment within the greenhouse and thus, affect the agronomic characteristics and yield traits of hemp. G1 reported the best results as it increased soil temperature and PAR values by 11-16% and 50-110% respectively, compared to G4. Concurrently, the majority of the bud characteristics were significantly improved in G1. Even though further research should be conducted in order to define the most suitable films for greenhouse hemp production, our results indicate that the optical properties of the greenhouse cover materials affect its yield and should always be considered.

Drought stress is one of the most important environmental factors which can limit the lentil production. To evaluate the effect of drought stress at flowering and pod filling stages on growth indices of lentil cultivar Kimiya (a new high yielding lentil cultivar for moderate cold and semi warm climate of Iran), an experiment was conducted at the research greenhouse of Higher Educational Complex of Saravan in completely randomized design with four replications. The drought stress was applied by withholding irrigation until the soil moisture reached to 20% of field capacity at stages of flowering and pod filling. In this experiment, we measured grain yield per plant, growth indices including plant leaf area (PLA), relative growth rate (RGR), plant growth rate (PGR), and net assimilation rate (NAR). Results showed that the flowering stage in lentil plant is more sensitive to drought as exhibited significant decline in PLA, RGR, PGR and NAR. PGR declined at the end of growing season when vegetative growth stop, senescence of leaves, the reduction of NAR, and the allocation of assimilate to the seeds.
