Physiological changes in wheat seeds during the artificial drying process
Berghetti, Juliano; Padilha, Matheus Santin; Borba, Paulo Tarcísio Domatos de; Coelho, Cileide Maria MedeirosThe desiccation tolerance presented by orthodox species is a characteristic that allows the loss of water keeping the seed viable. However, the reduction of the moisture content by drying, has a critical limit, and a loss beyond this limit results in a reduction in the physiological quality of the seeds, TBIO Sossego cultivar. The objective of this study was to evaluate the physiological changes resulting from ...
Caracterização da variabilidade espacial do índice relativo de clorofila na cul...
Pias, Osmar Henrique de Castro; Santi, Antônio Luis; Cherubin, Maurício Roberto; Berghetti, Juliano; Oliveira, Thiago Campos deA aplicação localizada de nitrogênio, baseada no índice relativo de clorofila das folhas, pode proporcionar inúmeros benefícios econômicos e ambientais, no entanto, o conhecimento sobre a metodologia de amostragem ainda é incipiente. Nesse sentido, este estudo objetivou avaliar o uso de diferentes malhas amostrais na caracterização da variabilidade espacial do índice relativo de clorofila das folhas da cultura ...

de Castro Pias, Osmar Henrique; Berghetti, Juliano; Somavilla, Lucindo; Bisognin Cantarelli, EdisonThe aim of this study was to evaluate the production of cedar seedlings according to the size of containers and nutrient sources. It was tested three types of containers (Root trainers, plastic bag and plastic vase), three sources of fertilization (Conventional, Kimcoat® and Osmocote®) in seven evaluations. The cedar seedlings in root trainers, fertilized with source Osmocote® presented the greatest increments ...

Pias, Osmar Henrique de Castro; Cantarelli, Edison Bisognin; Berghetti, Juliano; Leschewitz, Rogério; Kluge, Elizandro Ricardo; Somavilla, LucindoThe objective of this work was to define the best doses of Osmocote® for Apuleia leiocarpa seedling production for 60 and 90 days residence in the seedling nursery after the transplanting and to observe the chlorophyll index response of the seedlingsduring the studying period. The experimental design used was completely randomized, with five treatments and ten repetitions. The treatments consisted of increasing...
