BIOPHOTONICS: ACCLIMATION OF PRE-SPROUTED SUGARCANE SEEDLINGS IN PROTECTED ENVIRONMENT REA
Almeida Neto,Luiz A.; Pandorfi,Héliton; Moraes,Alex S.; Guiselini,Cristiane; C. Júnior,José J. Florentino.
ABSTRACT Sugarcane is considered one of the main alternatives for biofuel production and an important product of Brazilian agriculture, so it is indispensable to adopt new techniques for its cultivation and management. Thus, the present study aimed to evaluate the effect of the quality of supplemental lighting, based on light-emitting diode (LED), on the acclimation of pre-sprouted sugarcane seedlings in a protected environment. The experimental design was completely randomized, consisting of three supplemental LED lighting systems, with light proportions of 90% red + 10% blue (R:B 90/10), 80% red + 20% blue (R:B 80/20) and 70% red + 30% blue (R:B 70/30), and a control, with natural solar radiation, with 5 replicates. Multivariate principal component...

Multivariate analysis of the behavior and physiology of Girolando heifers in pasture AGRIAMBI
Batista,Pedro H. D.; Almeida,Gledson L. P. de; Pandorfi,Héliton; Melo,Airon A. S. de; Moraes,Alex S.; Guiselini,Cristiane.
ABSTRACT The objective of this study was to evaluate the thermal effect on the behavioral and physiological changes of Girolando heifers by means of principal components analysis. The research was conducted in the Agreste region of the state of Pernambuco, Brazil. Three heifers submitted to the continuous grazing system were used. For the determination of the thermal effect on the animals, the variables dry bulb temperature and relative air humidity were recorded, which allowed to determine the temperature and humidity index and the specific enthalpy. The physiological variables monitored were the respiratory rate, rectal temperature and skin temperature. The quantified behavioral indicators were walking, drinking, eating, ruminating and leisure, to...

Photo-selective shade nets on the production and quality of sugarcane plantlets AGRIAMBI
Cordeiro Júnior,José J. F.; Pandorfi,Héliton; Barbosa Filho,José A. D.; Moraes,Alex S.; Almeida Neto,Luiz A. de; Guiselini,Cristiane.
ABSTRACT Brazil is the world’s largest producer of sugarcane (Saccharum officinarum L.) and research aimed at propagation has promoted higher quality in production. The objective of this study was to investigate the effect of the variation of micrometeorological elements on the survival and quality of pre-sprouted sugarcane plantlets. The study was carried out in a protected environment (UFRPE). Plantlets of the cultivar RB92579 were obtained by the technique of production of pre-sprouted plantlets. The protected environments were divided into four modules covered with low-density polyethylene plastic + photo-selective shade nets and one module without shade net. Micrometeorological data of global and photosynthetically active solar radiation, air...

Sprouting of pre-sprouted sugarcane seedlings and micrometeorological variables under photo-selective nets AGRIAMBI
Cordeiro Júnior,José J. F.; Guiselini,Cristiane; Pandorfi,Héliton; Moraes,Alex S.; Menezes,Dimas; Almeida Neto,Luiz A. de.
ABSTRACT Sugarcane is a grass species that stands out worldwide in the production of ethanol. Brazil is the world’s largest producer and leader in exports, responsible for more than 50% of the products that are marketed worldwide. The objective of this study was to investigate the effect of photo-selective nets on micrometeorological variables and on sprouting of pre-sprouted sugarcane seedlings. The experiment was carried out in a protected environment at Universidade Federal Rural de Pernambuco - UFRPE, in a completely randomized design. Seedlings of cultivar RB92579 were obtained by the technique of production of pre-sprouted seedlings. The protected environment was divided into four modules corresponding to the treatments: covered with anti-UV...
