Morphology and anatomy of the diaspores and seedling of Paspalum (Poaceae, Poales)

RESUMO O conhecimento relativo ao diásporo e ao desenvolvimento pós-seminal de Paspalum L. é importante para a conservação da biodiversidade dos campos, devido sua importância na representatividade e no melhoramento genético de pastagens. A morfologia do diásporo e do desenvolvimento pós-seminal de Paspalum dilatatum Poir. (rizomatosa); P. mandiocanum Trin. var. subaequiglume Barreto (estolonífera), P. pumilum Nees. (cespitosa decumbente) e P. urvillei Steud. (cespitosa ereta) foi descrita procurando distinguir as espécies com diferentes formas de crescimento, e levantar características úteis para a taxonomia. P. dilatatum se diferencia por apresentar diásporo oval, de maior tamanho que as demais, com cinco nervuras salientes e tricomas; P. urvillei por apresentar diásporo com uma nervura central mais desenvolvida do que as duas nervuras laterais e tricomas; P. mandiocanum var. subaequiglume por apresentar diásporo com tricomas apenas na margem; e P. pumilum por apresentar diásporo glabro. A cariopse envolve a semente que apresenta embrião diferenciado, disposto lateralmente; apresenta hilo elíptico em todas as espécies estudadas e rostelo em P. dilatatum e P. mandiocanum var. subaequiglume. O desenvolvimento pós-seminal é semelhante nas quatro espécies e se inicia com a germinação, que é marcada pela emergência da coleorriza, seguida pelo coleóptilo. Essas características são comuns às demais Poaceae já estudadas, indicando um padrão para a família e não diferenciam as formas de crescimento.

Germinação de sementes e desenvolvimento inicial de Erythrina mulungu (Mart. ex. Benth)

The aim of this study was to determine the best pre-germination treatments for seeds and the best size container for seedlings growing of coral tree Erythrina mulungu (Mart. ex. Benth). Among the treatments applied to seeds, scarification with sulfuric acid during 10 minutes and cutting stylus in the region opposite to hilum resulted, respectively, in highest values of germination percentage (82.8% and 82.1%) and rates of germination speed (1.15 and 1.71). The biometric variables indicated no effect of container size on leaf area and dry mass plants. At 63 days after sowing, although with Dickson quality score statistically similar (mean 0.26), only plants grown in small and large bags reached the diameter collect close to 5 mm, minimum recommended for field planting. According to the results, for initial development of coral tree, it is recommended pre-seed treatment with sulfuric acid commercial, sowing in plastic bags of 17 x 20 cm, and wait 63 days before planting in the field.

Avaliação dos dados obtidos em um programa de esterilização cirúrgica de gatos em Araçatuba, SP no período de 1996 a 2010

Cats are gradually occupying a more important position as pets and this preference is a result of how easy cat maintenance in an urban environment is, even though they are very prolific and need surgical sterilization. This paper aims at evaluating obtained data within 15 years of research in a university service program that offers free cats sterilization surgery. We carried out a statistical analysis of data shown in the records of animals treated by the program. Surgical sterilization was performed on 647 animals (409 females – 63% and 238 males – 37%). Unilateral cryptorchidism was observed in 9 (3.8%) male cats. Forty (10%) female cats were pregnant at the time of the surgery and the treatment with contraceptives was observed in 67 (16.4%) female cats. One death occurred during anesthesia recovery and 2 cats were euthanized because of wound infection, totalizing an amount of 0.5% of severe complications. From 1996 to 2004, 212 female cats were spayed (122 adults and 90 prepubertal) and during that time two different approaches for ovariohysterectomy were compared: flank laparotomy and ventral midline celiotomy. The flank laparotomy approach was used in only 46 female cats (21.7%) due to some disadvantages observed – the need of an incision on each flank in prepubertal or nulliparous animals and the difficulty or impossibility of total uterus removal. In the same period, 105 male cats underwent orchiectomy via an open technique in which the spermatic cord was linked with nylon thread. From 2005 to 2010, 197 females (106 adults and 91 prepubertal) were spayed. The minilaparotomy technique was used to perform ovariohysterectomy on 139 female cats (70.6%). In this procedure, ovaries and uterus were exteriorized in a blind fashion with a hook through a small midline incision. The traditional midline ovariohysterectomy, which incision length permits direct visualization of the ovaries and uterus, had to be performed in 58 (29.4%) female cats due to advanced pregnancy, full urinary bladder during surgery or obesity. Over the past 6 years, 133 male cats (48 adults and 85 prepubertal) were castrated by means of an open technique in which the spermatic cord was tied to itself. The demand for surgeries during the project demonstrated that people are becoming aware concerning the importance of sterilization when facing cat overpopulation and abandonment.
