Avaliação da morfologia interna de sementes de Acca sellowiana O. Berg por meio de análise de imagens
Provedor de dados: Revista Brasileira de Fruticultura
Autores: Silva,Vanessa Neumann; Sarmento,Marcelo Benevenga; Silveira,Ana Carolina; Silva,Clarissa Santos; Cicero,Silvio Moure.
Acca sellowiana O. (Berg) Burret é uma fruteira nativa da região Sul do Brasil e do Uruguai, que apresenta grande potencial de uso na recuperação de áreas degradadas. O objetivo deste trabalho foi avaliar a morfologia interna de sementes de Acca sellowiana O. Berg por meio da análise de imagens de raios X e relacionar os resultados com a germinação das sementes. Sementes de Acca sellowiana O. Berg, representadas por três lotes, foram analisadas pelo teste de raios X e, posteriormente, conduzidas ao teste de germinação, com avaliação aos 44 dias após a semeadura. As imagens de raios X foram analisadas com o software ImageJ. A análise das imagens radiográficas de sementes de Acca sellowiana permite a mensuração das áreas internas livres, assim como a...

Computerized imaging analysis of seedlings for assessment of physiological potential of wheat seeds
Provedor de dados: Revista Brasileira de Sementes
Autores: Silva,Vanessa Neumann; Gomes Junior,Francisco Guilhien; Cicero,Silvio Moure.
Nowadays, image analysis is one of the most modern tools in evaluating physiological potential of seeds. This study aimed at verifying the efficiency of the seedling imaging analysis to assess physiological potential of wheat seeds. The seeds of wheat, cultivars IAC 370 and IAC 380, each of which represented by five different lots, were stored during four months under natural environmental conditions of temperature (T) and relative humidity (RH), in municipality of Piracicaba, Stated of São Paulo, Brazil. For this, bimonthly assessments were performed to quantify moisture content and physiological potential of seeds by means of tests of: germination, first count, accelerated aging, electrical conductivity, seedling emergence, and computerized analysis of...

Relationship between eggplant seed morphology and germination
Provedor de dados: Revista Brasileira de Sementes
Autores: Silva,Vanessa Neumann; Cicero,Silvio Moure; Bennett,Mark.
Structural differences such as abnormalities, damage and free spaces in seeds may affect germination. The aim of this study was to study the relationship between eggplant seed morphology and seed germination. Ten seed lots of the eggplant cultivar Embu were evaluated by X-ray image analysis and the germination test. Seed image analysis was performed by Image Pro Plus® software and the whole seed area and free space between the embryo and endosperm were measured. The internal seed area filled by the embryo and endosperm was calculated from the difference between the whole seed and free space areas. Based on these results and visual seed analysis, seeds were classified into three categories and information on germination was obtained for each one. X-ray...

Image seedling analysis to evaluate tomato seed physiological potential
Provedor de dados: Revista Ciência Agronômica (RCA)
Autores: Silva,Vanessa Neumann; Cicero,Silvio Moure.
Computerized seedling image analysis are one of the most recently techniques to detect differences of vigor between seed lots. The aim of this study was verify the hability of computerized seedling image analysis by SVIS® to detect differences of vigor between tomato seed lots as information provided by traditionally vigor tests. Ten lots of tomato seeds, cultivar Santa Clara, were stored for 12 months in controlled environment at 20 ± 1 ºC and 45-50% of relative humidity of the air. The moisture content of the seeds was monitored and the physiological potential tested at 0, 6 and 12 months after storage, with germination test, first count of germination, traditional accelerated ageing and with saturated salt solution, electrical conductivity, seedling...

Creole bean seeds microbiolization with doses of Trichoderma harzianum
Provedor de dados: Ciência Rural
Autores: Dalzotto,Laís; Tortelli,Brenda; Stefanski,Francine Spitza; Sacon,Deivid; Silva,Vanessa Neumann; Milanesi,Paola Mendes.
ABSTRACT: In the search for improved yields, seed treatment by microbiolization has been used as an alternative to chemical treatment. The objective was to verify the physiological and sanitary quality of creole bean seeds, var. Chumbinho, after microbiolization with doses of a commercial product (c.p.) with Trichoderma harzianum (strain ESALQ-1306). The treatments were: T1) 100 mL c.p./100 kg seeds; T2) 150 mL c.p.; T3) 200 mL c.p.; T4) 200 mL of chemical treatment (c.p., 250 g L-1 fipronil + 25 g L-1 pyraclostrobin + 225 g L-1 thiophanate-methyl); and T5) control (without coating of seeds). The tests were: sanitary test (blotter test); germination and first count; accelerated aging, cold germination without soil, speed of germination rate (SGR), seedling...

Avaliação do vigor de sementes de girassol por meio de análise de imagens de plântulas
Provedor de dados: Ciência Rural
Autores: Rocha,Cartiane Rubshirley Macêdo da; Silva,Vanessa Neumann; Cicero,Silvio Moure.
O trabalho teve como objetivo avaliar a eficiência do sistema computadorizado de análise de imagens de plântulas Seed Vigor Imaging System (SVIS(r)), em comparação com os outros testes recomendados para determinação do vigor de sementes de girassol. Foram utilizados dez lotes de sementes, cultivar Catissol 01, os quais foram avaliados quanto ao potencial fisiológico por meio dos testes de germinação, envelhecimento acelerado, emergência de plântulas em areia e em campo e análise de imagens de plântulas com o sistema SVIS(r), aos 0 e 4 meses de armazenamento. O delineamento experimental utilizado foi inteiramente casualizado para os testes realizados em laboratório e blocos ao acaso para o teste de emergência de plântulas em campo; em ambos os casos, foram...
