Seleção de variedades de soja (Glycine Max (L.) Merril ): I. Analises Bromatológicas

O presente trabalho foi realizado com o fito de estabelecer uma seleção prévia entre 32 variedaeds de soja (Glycine max. (L.) Merril), com base nas análises bromatológicas das sementes. Foram determinados teores de umidade (U), cinzas (RM), proteína bruta (PB), gordura bruta ou extrato etéreo (EE), fibra bruta (F) e extrativo não nitrogenado (ENN). As análises da variância permitem tirar as seguintes conclusões: 1) Entre as variedades classificadas no grupo forrageiro e comestível, tem-se: Mandarin 8a (40,16% PB), Bicolor de Calai (39,64% PB) e Aliança (38,70% PB). 2) De acordo com a classificação estabelecida, para o grupo produtor de óleo, as variedades Lee, Hood, Lincoln (Blanco) Improved Pelican (2), Lincoln (Morado) e Improved Pelican (1), se destacam com 21,76, 21,65, 21,62, 21,35, 21,13 e 21,04% de EE respectivamente. 3) As variedades que apresentaram menor percentagem de fibra são: Hernónjn.0 107, Hood, Mogiana, Hill e Selection n.° 135, com 9,59; 9,62; 9,68; 10,02 e 10,12% F respectivamente. 4) Encontrou-se uma correlação positiva entre o teor de proteína bruta e o de cinzas.

Observações preliminares sôbre a longevidade dos "Seedlings" de feijoeiro - Phaseolus vulgaris : em função das reservas cotiledonares

According previous studies about longevity in maize by ACCORSI e ADÂMOLI DE BARROS, (1961) the authors presents in this paper the results of work on longevity of seedlings of beans. Seeds were separated in three groups according their weight, as followings: small 80-120 mg; medium 130-140 mg and big 150-200 mg. The sowing of the seeds was made in pure sand and the seedlings were distributed in distil. water and in complete solution of Arnon and Hoagland. Each treatment was made in two replications with eight seedlings by treatment. At present time the following conclusions can be related: 1.°) - Eight days after germination, the cotiledones of all the seedlings started to fell down, fourteen days after, all cotiledones had fell down. 2.°) - Fifteen days after germination, the seedlings in nutritive solution showed better development than those in distil. water. Table I e II gives results. 3.°) - All seedlings in distil. water showed symptoms of N, Ca, Fe deficiencies. 4.°) - Twenty nine days after germination the seedlings in distil. water manifested exhaust trace, by falling of the leaves and death of some plants although the aplicai buds keep green. 5.°) - After thirty-one days the plants in nutritives solution was in better condition than those in distil. water, although some alteration aboved mentioned was observed. The causes of this alteration are being studied. 6.°) - In many plants in complet solution the seminal leaves showed clorosis initial and some with necrosis, although apical buds keeps in ativity. 7.°) - Symptoms of clorosis and necrosis in diferents stages were observed in all leaflet; these symptoms were more strong in the groups of little seed and medium seeds.

Observações preliminares sobre a malformação em inflorescencias de mangueira (Mangifera indica L.) e fungo, alguns insetos e ácaro nelas encontrados

A malformação de inflorescências e o superbrotamento de gemas terminais e axilares de mangueiras dos Estados de São Paulo e Pernambuco são relacionados com o ácaro Aceria mangiferae Sayed, 1946 (Acarina, Eriophyidae) e o fungo Fusarium moniliforme subglutinans, sendo êste último considerado, empíricamente, como o principal agente causal da doença. Varios insetos associados às inflorescências de mangueiras foram coletados: lagarta de Eupithecia sp. (Tephroclystis), (Lepidoptera, Geometriidae, Hydriomeninae); Frankliniella cubensis Hood, 1925 (Thysanoptera, Thripidae); coleopteros pertencentes às familias Nitidulidae e Cryptophagidae.

Resting metabolic rate and protein turnover in apparently healthy elderly Gambian men.

Body composition, resting energy expenditure (REE), and whole body protein metabolism were studied in 26 young and 28 elderly Gambian men matched for body mass index during the dry season in a rural village in The Gambia. REE was measured by indirect calorimetry (hood system) in the fasting state and after five successive meals. Rates of whole body nitrogen flux, protein synthesis, and protein breakdown were determined in the fed state from the level of isotopic enrichment of urinary ammonia over a period of 12 h after a single oral dose of [15N]glycine. Expressed in absolute value, REE was significantly lower in the elderly compared with the young group (3.21 +/- 0.07 vs. 4.04 +/- 0.07 kJ/min, P < 0.001) and when adjusted to body weight (3.29 +/- 0.05 vs. 3.96 +/- 0.05 kJ/min, P < 0.0001) and fat-free mass (FFM; 3.38 +/- 0.01 vs. 3.87 +/- 0.01 kJ/min, P < 0.0001). The rate of protein synthesis averaged 207 +/- 13 g protein/day in the elderly and 230 +/- 13 g protein/day in the young group, whereas protein breakdown averaged 184 +/- 13 g protein/day in the elderly and 203 +/- 13 g protein/day in the young group (nonsignificant). When values were adjusted for body weight or FFM, they did not reveal any difference between the two groups. It is concluded that the reduced REE adjusted for body composition observed in elderly Gambian men is not explained by a decrease in protein turnover.

In the biological study, the development of the biological cycle of the insect under different feeding conditions was evaluated. The insects were fed on either mouse blood (c) or pigeon blood (p) using two types of rearing techniques (individual or group) at 28(graus) C and 90% relative humidity (which is equivalent to their natural environment). A fifth cycle studied, was fed on mouse blood reared on group, and mantained at laboratory environmental temperature. In the five cycles analyzed, it was found that groups on mouse blood at near natural conditions developed more rapidly (between 60 and 73 days) and had a lower rate of mortality (16.66%). The daily handling and changes in environment, of the individually reared insects, for observation of biological characteristics (no. and duration of bloodmeal, defecation and first fed of each stage) had a negative influence. None of the individuals fed on mouse or pigeon blood reached adult hood. It was found that the longevity and the fertility rate were significantly superior on couples maintained individually on mouse blood. These males had an average lifespan of 110,26 days and the females had an average lifespan of 104,46 days. The average number of eggs laid by each female was 21,26. Four couples kept in groups (five couples in each group) under the same condition, the longevity for males was 51,86 days and for females was 81,06 days. An average of 10,5 eggs were laid by each female. However, the percentage of fertile eggs was higher in couples kept in groups (72.15%) than in the individual couples (57.68%).

Rhipidocotyle gibsoni n. sp. from a Brazilian Freshwater Fish and Rhipidocotyle froesi n.sp. for r. baculum (linton, 1905) of Eckmann (1932) (Bucephalidae; Digenea)

Rhipidocotyle gibsoni n.sp. is described from Acestrorhynchus lacustris from Paraná River, brazil. It is most closely related to r. froesi n. sp. and to R. eckmanni in the shape of the cephalic hood, differing in the extent of the uterus, in the position of the vitelline follicles and in that the host is a freshwater fish. Rhipidocotyle froesi n. sp. is proposed for the marine specimens described by Eckmann (1932) as R. baculum (Linton, 1905).
