Ascorbic acid contents of some fruits and vegetables in Abakaliki were analyzed through titrimetric methods. The results recorded the concentrations (mg/100g) of ascorbic acids in various fruits as orange (15.47 ± 0.23), lemon (12.87 ± 0.45), grape (2.00 ± 0.10), paw-paw (46.40 ± 1.65), apple (2.20 ± 0.10), banana (1.87 ± 0.06), carrot (1.80 ± 0.04), pineapple (2.80 ± 0.10), water melon (2.27 ±...

Four-week-old French Colombard plants rooted from green cuttings were inoculated with 0, 1,000, 2,000, 4,000, or 8,000 Meloidogyne incognita second-stage juveniles and maintained at 25 C night and 30 C day. Leaf area and dry weight and the rates of photosynthesis, stomatal conductance, and internal leaf CO concentration were measured at intervals up to 59 days after inoculation. Nematode stress...

In China, grape is one of the top five fruit crops for both bearing acreage and production. Recently, national production has been stalling because an increase in drought events. order to combat adverse effects on production, it imperative understand historical trend frequency during growing season. this study, we focused agricultural four growth periods grape: bud break-flowering, flowering-ve...

this research was conducted to study morphological and evaluation of genetic diversity of 15 grape cultivars in collections of agriculture and natural resources, research center of khorasan razavi based on completely randomized design with four replications. results showed extensive range of variations among cultivars and measured traits. in some key traits of tests for distinctness uniformity ...
