The results revealed that the pumpkin cultivars showed large variations in fruit stem length, single fruit weight, fruit length and flesh thickness, but small variations in initial flowering date. Significant, even highly significant correlations were found among the tested traits. Cluster analysis demonstrated that the 41 old Cucurbita moschata cultivars were divided into three groups, of which multiple traits of Group 1 were better than those in the other two groups. High similarities existed in three groups and the cultivars in each group. This research provided basis for selecting excellent traits and parents for the breeding of hybrids.展开更多

In addition, it occupies the second position, among the consuming countries of the drink. To investigate the chemical composition and quality of the coffee drink from Coffea arabica species, samples grown in the city of Ourinhos, the third most productive region in the state of Sao Paulo, a study of its properties and characteristics was conducted. The pharmacobotanical characteristics were investigated performed according to usual techniques in these researches through macroscopic and microscopic studies through cross-sections. The oil obtained for analysis was extracted by soxhlet, and the caffeine content was measured for green grains using High Performance Liquid Chromatography (HPLC) using as stationary phase, column C18 and gradient mobile phase formed by 80% water and 20% methanol. The concentration obtained was 44.983 ± 0.86 μg/mL. The antioxidant activity was measured in triplicate through the DPPH test of the in natura coffee oil, and presented antioxidant action of EC50 25.89 ± 1.16 μg/mL.展开更多
