Identity and genetic diversity of Pectobacterium spp., causal agents of potato soft rot in Zanjan, Iran

Zanjan province is one of the areas of potato production in Iran with more than 6917 ha of cultivation. One of the most important factors to limit potato cultivation is soft rot bacteria belonging to the family Enterobacteriaceae. During the years 2007 to 2008, different potato fields and the most important potato storages in Zanjan province were surveyed. Phenotypic identification of the strains was performed...

A study of intraspecific hybrid lines derived from the reciprocal crosses between wild accessions and cultivated cowpeas (Vigna unguiculata (L.) Walp.)

Cowpea (Vigna unguiculata (L.) Walp.) is an essential food legume in the (sub) tropical areas. Reciprocal crosses were performed using wild accessions for transferring genes of interest to cultivars (524-B/IT84S-2049). Of these, a low number of seeds were obtained because of crossing barriers. A seed sample of 17 F1 hybrids germinated after germination was 69.09%. A subdivision into seed sterility, partial seed...

Volatile constituents of essential oils isolated from different parts of Alpinia calcarata Rosc

The essential oils isolated from different parts of Alpinia calcarata Rosc. growing in Chittagong, Bangladesh, were analyzed by gas chromatography-mass spectrometry (GC-MS). The leaf oil contained 1,8-cineole (28.48%) and camphor (21.40%) as the major constituents. The stem sheath oil had fenchyl acetate (19.16%) and carotol (16.77%) as the major compounds. On the other hand, the root oil showed fenchyl...

Seasonal variation of fixed and volatile oil percentage of four Eucalyptus spp. related to lamina anatomy

This experiment was conducted during the four seasons: Spring, summer, autumn and winter of two successive annual cycles; 2008/2009 and 2009/2010 (starting from May 2008). Four Eucalyptus species were under investigation; Eucalyptus camaldulensis Dehnh., Eucalyptus cinerea F. Muell. ex Bentham, Eucalyptus citriodora Hook. and Eucalyptus globulus Labill. Seasonal variations in the amount of fixed and volatile oils in...

Study of citrus disease prevalence on four citrus varieties at the National Institute of Horticultural Research (NIHORT) Mbato, Okigwe, Imo State, Nigeria

The studies were conducted to determine the prevalence of diseases on four varieties of citrus. These are sweet orange (Citrus sinensis), tangelo (Citrus paradise X Citrus reticulate), grape (Citrus paradise) and lemon (Citrus limon). The study showed that, tangelo and sweet oranges were more susceptible to fungal attack than grape and lemon. The disease symptoms commonly observed included dieback on the four species of...

Correlation and heritability estimates of maize agronomic traits for yield improvement and Striga asiatica (L.) Kuntze tolerance

A study was carried out to estimate percent heritability and correlation coefficients of desirable maize agronomic characters under artificial infestation with Striga lutea. Forty five F1 hybrid maize of varied striga tolerance and their ten parents inbred were evaluated along with two check entries. This was sited in three locations representing different agro ecologies of south western Nigeria in 1999 cropping...

Phytochemical screening on four edible legumes (Vigna subterranean, Glycine max, Arachis hypogea, and Vigna uniguiculata) found in eastern Nigeria

he results of the phytochemical screening carried out on the seeds of Vigna subterranea (Bambara groundnut), Glycine max (Soya beans), Arachis hypogea(Groundnut) and Vigna uniguiculata (Black eyed peas) showed the presence of useful phytonutrients. The results showed that V. subterranea contained the highest percentage of alkaloids (0.41%) while A. hypogea showed...
