This study aimed to quantify the levels of resistance of 39 hybrids BClone 83 × Clone 02^of Coffea canephora var. conilon to the races II (v5) and XXXIII (v5,7,9) of H. vastatrix. To study the resistance of the genotypes, leaf discs were removed from the plants and spreaded on the top of a stainless steel screen inside gerbox as a moist chamber. The gerboxes were mantained at 22 ± 2 °C in the dark for 48 h and under 12 h of photoperiod, respectively. The hybrids were classified into four levels: resistant (R), moderately resistant (MR), moderately susceptible (MS) and susceptible (S). Leaf discs (%) containing sporulated lesions was the resistance component that had the greatest absolute correlation (0.95). The level of resistance of the hybrids varyied according to the race of the pathogen. The percentage of R, MR, MS and S of the hybrids to race II and XXXIII were 25 %, 25 %, 38 %, and 11 %, and 13 %, 37 %, 42 %, and 8 %, respectively. Nine (25 %) and five (13 %) hybrids were R to race II and XXXIII, respectively. Four hybrids (21, 30, 48 and 66) showed vertical resistance to races II and XXXIII. Possibly these hybrids have the resistance factor SH6, because they were resistant to race XXXIII v5,7,9. Leaf discs (%) with sporulating lesions can be used as a reference in future studyies of screening genotypes with horizontal resistance to C. canephora genotypes to leaf rust. |

Carotenoids were extracted from pressed palm fiber using supercritical CO2 and microencapsulated by spray-drying with gum Arabic. Twenty-eight tests were made. Emulsions were characterized with respect to droplet size and viscosity. The effects of solid content and spray-drying conditions on moisture, hygroscopicity, microencapsulation efficiency, and powder lipid oxidation were investigated. Particles produced at optimized process (35% of solids, feed flow of 26%, temperature of 166 °C, and atomization air flow of 40 mm) were evaluated for major carotenoids identification and fatty acid profile. Higher solid content led to higher encapsulation efficiency and lower lipid oxidation, which was related to the higher emulsion viscosity and lower droplet size. Increasing atomization air flow and temperature resulted in higher lipid oxidation. Moisture increased and higroscopicity decreased when higher feed flow and lower temperature were used. Microparticles presented high content of monounsaturated fatty acids, ?-, ?-, and (9Z)-?-carotene and reflected the composition of un-encapsulated oil. |
