Growth of pea plants (Pisum sativum L.) subjected to different soil water potentials : physiological indexes

A ervilha é cultivada no Brasil Central, durante o inverno seco, exigindo para o pleno êxito da cultura o uso da irrigação. Assim, o presente trabalho se propõe a avaliar os efeitos do potencial da água no solo nos índices fisiológicos da análise quantitativa de crescimento de plantas de ervilha (Pisum sativum L.). O experimento foi montado em casa de vegetação, em solos de textura argilosa, com delineamento experimental inteiramente casualizado, com quatro tratamentos decorrentes de potenciais mínimos da água no solo (-33, -100, -200 e -1500 kPa) em três repetições, cada qual contendo duas plantas de ervilha, cultivar Caprice. Os resultados obtidos evidenciaram que a redução do potencial água no solo, induziu o decréscimo na área foliar, sem interferir no comportamento da razão de massa foliar, razão de área foliar, taxa assimilatória líquida e taxa de crescimento relativo. _________________________________________________________________________________________ ABSTRACT: Peas are cultivated in the central region of Brazil, during the dry winter, demanding for the complete success the use of irrigation. Therefore, the present work has the aim of evaluating soil water potential effects on the indexes of physiological growth analysis of peas (Pisum sativum L.). The experiment was carried out in a greenhouse using soils of clayey texture, in a fully randomized design, with four treatments, based on minimum soil water potentials (-33, -100, -200 and -1500 kPa) in three replicates, each one containing two pea plants Caprice cultivar. The results obtained indicate that the reduction of soil water potential induced the decrease of leaf area, but did not interfer on the behaviour of leaf weight ratio, leaf area ratio, net assimilation rate and relative growth rate

Growth analysis in the potato crop under different irrigation levels

Conduziu-se um experimento na Fazenda São Manoel, localizada em São Manuel, SP, pertencente à Faculdade de Ciências Agronômicas da Universidade Estadual Paulista, com o objetivo de avaliar os efeitos de diferentes lâminas de irrigação no crescimento da cultura da batata (Solanum tuberosum ssp. tuberosum), cultivar Aracy. O ensaio foi instalado em um Latossolo Vermelho-Escuro, textura arenosa, sob uma cobertura de plástico. O delineamento experimental utilizado foi o de blocos ao acaso, com cinco tratamentos, cinco coletas de plantas para fins de análise de crescimento, e quatro repetições. Os tratamentos consistiam em irrigar a batata quando a tensão da água no solo atingia 15, 35, 55, 75 e 1.500 kPa. O aumento nas lâminas de irrigação induz incremento no índice de área foliar, na duração da área foliar, na taxa de crescimento relativo e na taxa assimilatória líquida. _________________________________________________________________________________________ ABSTRACT: An experiment was carried out at Fazenda São Manoel, pertaining to the Faculdade de Ciências Agronômicas of the Universidade Estadual Paulista, São Manuel, SP, Brazil, to evaluate irrigation levels in the potato (Solanum tuberosum ssp. tuberosum) growth, cv. Aracy. This work was installed in a sandy Dark-Red Latosol, under a plastic cover. The experimental design was an entirely randomized block composed by irrigation in the potato plots when the soil water potential has reached 15, 35, 55, 75 and 1,500 kPa, and five plant sampling time with four replicates. It was found that higher irrigation levels led to increase of the leaf area index, leaf area duration, relative growth rate and net assimilation rate

Fotossíntese, relações hídricas e crescimento de cafeeiros jovens em relação à disponibilidade de fósforo

O objetivo deste trabalho foi avaliar de que maneira a alta disponibilidade de fósforo no solo afeta a fotossíntese e o crescimento de mudas de cafeeiro arábica (Coffea arabica). Mudas da cultivar Ouro Verde com aproximadamente quatro meses de idade, cultivadas com boa disponibilidade hídrica, foram submetidas a três tratamentos quanto à disponibilidade de fósforo: quantidade recomendada de P, na literatura (PA); duas vezes a dosagem utilizada em PA (P+); e sem adição de P ao solo (P-). Após 70 dias da aplicação dos tratamentos, foram avaliados: as trocas gasosas, a atividade fotoquímica, o potencial de água da folha, a condutância hidráulica da planta (K L), a partição de matéria seca na planta, os teores de pigmentos e carboidratos, e a composição química das folhas. O tratamento P- influenciou negativamente a fotossíntese, e levou à restrição do crescimento das plantas. As plantas do tratamento P+ apresentaram maior teor foliar de P (~1,9 g kg-1), com incrementos na assimilação de CO2, na eficiência instantânea de carboxilação e na atividade fotoquímica - maior eficiência do fotossistema II e maior transporte aparente de elétrons - em relação às plantas do tratamento PA. Houve aumento em K L, maior teor de carboidratos foliares e maior teor de clorofila nas plantas que receberam o dobro da dose recomendada de P, as quais apresentaram maior produção de matéria seca em relação às de PA e P-

Management Of Lower Pole Renal Calculi

The lower calix is responsible for a significant incidence of kidneys with residual stone fragments. In addition to those with an anatomic caliceal disposition, stones located in damaged and dilated calices should be treated percutaneously.7450350

Bilateral Carcinoma In Situ Of Testis In Infertile Man

Abnormal seminiferous epithelium with atypical germ cells was studied in 2 previous cases. Embryonal carcinoma occurred within four and one-half years of testicular biopsy. Herein is reported another case of bilateral carcinoma in situ of the testis, presenting abnormal germinal morphology and infertility. The abnormal cells differed considerably from normal spermatogonia, presenting an increased diameter and dense chromatin masses. Apparently normal tubules were also present with normal spermatogenesis. Serum gonadotropins and chromosome study were normal. After bilateral biopsy patient was submitted to a right orchiectomy and left varicocelectomy. © 1985.256601604Dixon, Moore, Tumors of the male sex organs (1952) Atlas of Tumor Pathology, , Armed Forces Institute of Pathology, Washington, D.C, sect 8, fasc 31 b and 32Witschi, Migration of the germ cells of human embryos from the yolk sac to the primitive gonadal folds (1948) Contribution to embryology, 32, pp. 67-80. , ed. 7, Carnegie Institution, Washington, 209Curtis, Staggers, Treatment of the undescended testis with special reference to pathological anatomy (1960) J Urol, 83, p. 693Gilbert, Hamilton, Studies in malignant testis tumors.

The Importance Of Hyperprolactinemia In Impotence.

The role of serum prolactin in sexual dysfunction has not yet been clarified. Moderate elevations of prolactin levels, without any associated disorder, occur frequently. A random group of 600 patients was studied to determine the level of prolactin in which medical treatment was necessary. Among these patients 23 (3.8%) presented hyperprolactinemia and were divided into two groups: Group 1--Twelve patients with prolactin levels ranging from 20 to 40 ng/ml, and Group 2--Eleven patients with levels higher than 40 ng/ml. In Group 1, prolactin of all patients returned to normal levels after treatment, but only one patient (8.3%) achieved full erection; on the other hand, in Group 2, nine out of eleven patients prolactin returned to normal after treatment and 77.7% achieved full erection.111645445

The Influence Of Patient Education Level On The International Prostatic Symptom Score

The American Urological Association developed a questionnaire to quantify the severity of symptoms due to benign prostatic hyperplasia (BPH). An additional question relating to the impact of BPH on the quality of life was added, and this questionnaire became known as the International Prostate Symptom Score (I-PSS) and was adopted by the World Health Organization. The objective of our study was to determine the influence of education on the I-PSS and to analyze the relationship of the effect on the questionnaire when self-administered or administered by professional medical personnel. I-PSS was administered to 92 patients 50 to 81 years old (mean age 63) with BPH. Patients were assessed into 2 groups according to the level of education. Group 1 was composed of 68 patients considered literate and group 2 comprised 24 patients considered illiterate by UNICEF criteria. Patients received orientation about the questionnaire and the manner of completion. The symptom index was self-administered (subgroup P) and administered with physician help (subgroup D). Statistical analysis was done using Wilcoxon method for nonparametric samples and regression analysis. The difference between P and D subgroups in group 1 was not statistically significant (p = 0.55). However, the difference between subgroups P and D in group 2 was statistically significant (p less than 0.001). There was no correlation between the mean I-PSS in subgroup D of literate and illiterate groups. Our study suggests that illiterate patients were not able to answer the questionnaire but with the help of professional medical personnel the I-PSS could be extended to this group of patients without impairing the quality. © 1995 American Urological Association, Inc.15419799Madsen, Iversen, A point system for selecting operative candidates (1983) Benign Prostatic Hypertrophy, pp. 763-765. , F.
