Its fruit is early-mid maturing and in the shape of a long finger.The immature fruit is in dark-green and mature fruit is in dark-red.The average length, width and flesh thickness are 15.7, 1.9 and 0.17 cm, respectively. The yield of dry pepper is 6 750 kg/hm^2. The average contents of Vc, soluble solid and dry matter are 1.30 mg/g, 10%, and 14% respectively. The cultivar has good resistance to pepper blight, viral disease and anthracnose. It shows strong tolerance to heat, water logging and drought. It is suitable for spring field cultivation in Gansu, Xinjiang and Inner Mongolia.展开更多

Mango carotenoids are synthesized in mango fruit during ripening. A major by-product of mango fruit is the skin, which is available after the fruits is consumed or used, particularly in the preparation of jams and fruit juices by the fruit canning industry. The objective of this study was to investigate the effects of dietary mango skin （MS） or mango skin combined with paprika extracts （PE） on production performance, egg quality, and egg yolk polyphenols. Total of 60 44-week-old Boris Brown hens was assigned, based on egg production rate and body weight, to 6 groups （10 birds in each group）. The laying hens were fed a basal diet （control group, 18 CP, 2,800 kcal/kg ME）, a basal diet supplemented with 0.1% PE, 1% or 5% MS, or with a mixture of 0.1% PE with 1% or 5% MS respectively. During the three-week experimental feeding period, the birds had free access to feed and water. Feed consumption was measured weekly and egg production was recorded daily. The results for initial body weight, feed consumption, hen-day production, egg mass, mortality, and final body weight did not indicate any effects of the different treatments （P 〉 0.05）. There were no significant differences （P 〉 0.05） in shell-breaking strength, shell thickness, shell ratio, yolk ratio or Haugh units, except in the case of egg yolk color. Roche yolk color fan scores were better in all experimental groups than in the control （P 〈 0.0001）. The yolk color, yellow index, and ratio of redness to yellowness were greater （P 〈 0.0001） in the 0.1% PE, the 0.1% PE ＋ 1% MS, and the 0.1% PE ＋ 5% MS group than in the 1%, 5% MS, and control groups. Compared with the control, lightness was decreased significantly in the 0.1% PE, the 0.1% PE ＋ 1% MS, and the 0.1% PE ＋ 5% MS groups （P 〈 0.05）, whereas redness was increased significantly in the 0.1% PE, 0.1% PE ＋ 1% MS, and 0.1% PE ＋ 5% MS groups （P 〈 0.0001）. No significant differences among the treatments were observed in either yellowness or egg yolk polyphenols. The results of the present experiment indicate that dietary mango skin or mango skin combined with paprika extracts did not show adverse effects on production performance, egg quality or egg yolk polyphenols. Moreover, supplementation with only mango skin did not enhance egg yolk color.展开更多
