The present study focused on the comparison the chemical composition of virgin olive oil samples obtained from fruits of the main Tunisian olive cultivar (Chemlali) grown in four planting densities (156, 100, 69, and 51 trees ha(-1)). Despite the variability in the triacylglycerols and volatile compounds composition, the quality indices (free fatty acids, peroxide value, and spectrophotometric ...

The oil content in olive fruits of different sizes from irrigated high (‘on’) and low (‘off’) yielding olive trees of cvs. Barnea and Manzanillo were determined at different stages of fruit maturation. The fruit size range at all stages of maturation is significantly higher on low yielding ‘off’ trees than on high yielding ‘on’ trees. The oil content in the mesocarp of olive fruits is not yield...

We developed a new approach using RAPD fingerprints to distinguish 37 currant cultivars from northeastern China based on optimization of RAPD by choosing 11 nucleotide primers and strict screening PCR annealing temperature. We found that the manual cultivar identification diagram (MCID) approach clearly developed fingerprints from 8 different primers that were useful for cultivar identification...

The Fusarium mycotoxin deoxynivalenol (DON) can cause cell death in wheat (Triticum aestivum), but can also reduce the level of cell death caused by heat shock in Arabidopsis (Arabidopsis thaliana) cell cultures. We show that 10 μg mL(-1) DON does not cause cell death in Arabidopsis cell cultures, and its ability to retard heat-induced cell death is light dependent. Under dark conditions, it ac...

Cotton (Gossypium hirsutum L.) is one of the most commercially important fiber crops in the world. Compared with other crops, cotton represents a recalcitrant species for regeneration protocols. The development of efficient and rapid regeneration protocol for elite Indian cotton variety could help improve the quality characteristics and biotic or abiotic stress tolerance. Here we report a novel...

Legumes are a large and economically important family, containing a variety of crop plants. Alongside different cereals, some fruits, and tropical roots, a number of leguminosae evolved for millennia as crops with human society. One of these legumes is Pisum sativum L., the common garden pea. In the past, breeding has been largely selective on improved above-ground organs. However, parameters, ...

Evaluation of the incidence of the leaf spot disease caused by the biotrophic pathogen Fusicladium oleagineum on two olive cultivars (Olea europaea L.) was carried out during six years (2009/2015) in groves located at Touiref (North West of Tunisia). The studies focused on Meski and Chetoui cultivars. The evaluated foliar incidence of disease was analyzed in relationship with some factors. Dise...

The influence of three salts (KN03, NH4N03 and (NH4>2S04) in different concentrations, on the growth and mineral composition of olive seedlings cultured in vitra and in greenhouse conditions, was studied. The best growth was obtained in in vitra culture through the applications of NH4N03, in concentrations of 10 and 20 mM of N. Addition of (NH4)2S04 clearly damaged the seedlings and increased t...

Fertigation is widely used in the new intensive olive orchards, although, there is not enough information for a rational management of this practice. Preliminary results of an fertigation experiment iniciated in 1999 in a mature olive orchard of the cultivar ‘Manzanilla de Sevilla’ are presented. Four treatments were established: T1(no fertilizer) and T2, T3 and T4, in which the trees received ...
