Unidade amostral para determinação de massa média de frutos em lichieira em sistema orgânico e convencional

The experimental unit of measurement is a suitable technique to estimate the average character in evaluation, and experimentation should be well understood and executed, because the precision characterizes the quality of the inferences of the results. This research aimed to analyze the possibility to obtaining the quantity of fruit required for sampling of lychee plants, to determining the average mass of the fruits, with less sampling error. One hundred fruits were collected, in a hectare, in two cropping systems, conventional and organic, being one fruit per plant. From the data of fruit mass was used the Excel® to calculate the average fruit mass and number of fruits samples needed to represent the area of the producer. The results show that to achieve a sampling error of 10% for determining the average mass of fruit, 400 fruits should be collected for organic system and 370 for the conventional, while for 20% sampling error, it is necessary to collect 250 fruits per hectare in organic system and 220 in the conventional.

Ocorrência de pragas em algodoeiro geneticamente modificado (Bt) e convencional

The study aimed to evaluate the occurrence of pest and management of cotton genetically modified with the introduction of the bacterium Bacillus thunringiensis compared to conventional cotton in the 'Cerrado' region, installing the field experiment in 2007/2008 in Chapadão do Sul-MS. The experimental design was randomized blocks in a 2 × 3 factorial, with two managements of insecticides (with and without insecticides to control lepidopteran) and 3 modes of use of cultivars: 100% transgenic (NUOPAL), 100% non transgenic (Deltaopal) and interior area with transgenic (80% NUOPAL) with non-transgenic border (20% Deltaopal) with five replications. Evaluations were performed weekly of pest infestation, observing in 15 plants per plot the number of Alabama argillacea, Heliothis virescens and Spodoptera frugiperda. Based on these results it was concluded that: the occurrence of A. argillacea and H. virescens was lower in treated transgenic cultivar. There were no differences between transgenic and conventional farming on the occurrence of S. frugiperda.

Absorção de nitrogênio pelo algodoeiro herbáceo em dois sistemas de cultivo

The study of nutrient uptake is of fundamental importance to plant nutrition, as well as tell the time (growth stage) being absorbed by the culture, also signals to the levels of fertilizer to be used. Aiming to establish the uptake of nitrogen for cultivation of cotton (Gossypium hirsutum L. r. latifolium Hutch.) led to an experiment in a Alfissol under randomized block design with two treatments, sowing conventional tillage and after tillage on the straw of previous crop (millet), with five replicates. Samples were taken according to the phenology and plants development. The dry matter accumulation in cotton is linear and increasing until the period of large boll, being more intense with the appearance of flowers and boll, or 50 to 100 days after emergence. The nitrogen content is higher in newly emerged plants, having peaks at the beginning of the appearance of squares and flowers, and from the appearance of small boll, the nitrogen content in the plant decreases linearly. The extraction of nitrogen is bigger from the appearance of flowers (55-60 days after emergence).

Avaliação leucocitária de cães com linfoma submetidos ao protocolo de Madison-Wisconsin pela técnica convencional e citometria de fluxo

Lymphoma is the most common hematopoietic tumor in dogs and one of the malignant tumors with higher occurrence in this species. It is a great experimental model due to its resemblance with the non-Hodgkin lymphoma in humans. Considering the importance of the overall changes that result from to this kind of neoplastic tumor and those due to polichemotherapy this study aimed to evaluate the absolute leukon count and the total count of CD45+ cells in the blood of 25 dogs with lymphoma. Findings were crosschecked since diagnose and then once weekly during the first eight sessions of the Madison-Wisconsin chemotherapic protocol. Total granulocyte, lymphocyte and monocyte counts obtained from a conventional automatic counter and by flow cytometry were compared. Results did not reveal statistically significant changes between the two techniques.
