A real-time PCR assay conjugated with the fluorescent SYBR Green I dye has been developed for rapid, sensitive and quantitative detection of ‘Candidatus Phytoplasma prunorum’ in its natural hosts, in stone fruits such as apricot plants and in the insect vector Cacopsylla pruni. The selected primers amplified specifically a fragment 153 bp long from the rplV (rpl22) gene of ‘Ca. P. prunorum’ and...

Samples of stem exudate and plant tissue collected from field-grown soybean (Glycine max [L.] Merr.) plants were analyzed for allantoin and allantoic acid. Nitrogen in nitrate plus amino acids exceeded ureide N concentration in stem exudate prior to flowering. During all of reproductive development (from about 40 days after planting until maturity), ureide N concentration was two to six times g...

The effect of pre and post-anthesis shading (20% of incident radiation) on pericarp development, cotyledon cell number and seed growth dynamic of fruits from three positions in the capitulum (peripheral, mid and central) of two sunflower (Helianthus annuus L.) genotypes were studied at two locations. Both shading treatments reduced pericarp weight, fruit volume and total yield per plant. Plants...

We studied a community of frugivorous Lepidoptera in the lowland rainforest of Papua New Guinea. Rearing revealed 122 species represented by 1,720 individuals from 326 woody plant species. Only fruits from 52% (171) of the plant species sampled were attacked. On average, Lepidoptera were reared from 1 in 89 fruits and a kilogram of fruit was attacked by 1.01 individuals. Host specificity of Lep...

The experiment included four levels of NAA, 10, 20, 30, and 40 ppm, GA3, administered topically evaluated in comparison to a control (water spray). measurements several parameters, such as fruit set, size, volume, weight 100 fruits, yield per plant, hectare, were made. According the experiment, GA3 at ppm enhanced weight, volume yield. Combining NAA+GA3 proved effective improving yield, quality...

This study shows the effect of soil structure, soil texture and different types of nutrients on the growth of Ammi visnaga (L.) Lam, as well as the yield of the fruit crop and its content of the main active principals (ɣpyrones). The study was carried out in several localities in Two Arabian countries in North Africa; Egypt and Sudan. Egypt: at three localities:-1st at Mepaco Farm in Enshas El-...

The present investigation was aimed at determining the effects of arbuscular mycorrhiza on growth and yield of chilli plants grown under salinity condition. Seeds of chilli were sown in sand beds in size 5×1m under shade net condition at Botanical Garden, Department of Botany, Annamalai University. Forty days old seedlings (DAS) were transplanted into pots (one seedling per pot) until the fruit...

BACKGROUND/OBJECTIVES The objective of this study was to measure and/or estimate the total antioxidant capacity of the Korean diet. MATERIALS/METHODS Eighty-one plant foods that were expected to exhibit rather high antioxidant activities were selected from the Korean diet using the Fifth Korean National Health and Nutrition Survey (KNHANES V). These foods were categorized into 11 food groups:...

ABSTRACT In pineapple cultivation, it is common to cover the fruit with newspaper, in order avoid scalding caused by sunburn. However, scarcity of material and large labor force required have led search control alternatives. This study aimed evaluate use shading screens production quality ‘Smooth Cayenne’ pineapple. A randomized blocks experimental design was used, five treatments (fruits cover...

Alcoholic fermentations were performed adapting the technology to exploit the residual thermal energy (hot water at 83-85°C) of a cogeneration plant and to valorize agricultural wastes. Substrates were apple, kiwifruit and peaches wastes and Corn Threshing Residue (CTR). Saccharomyces bayanus was chosen as biocatalyst. The fruits, fresh or blanched, were mashed; CTR was gelatinized and liquefie...
