abstract field bindweed is an important perinial weed of agricultural crops word-wide. there are plant pathogen fungus which could cause necrotic spots on the leaves and stems of convolvulus arvensis under natural coditions. in order to evaluate the effects of weed growth stage and length of dew period on disease development causes by aletrnaria alternata and fusarium sp. two expriments were pe...

Morinda citrifolia L., commonly known as noni, is a growing global commodity. As such , there is a need for rapid and inexpensive identity tests of noni fruit and leaf products. Thin Layer Chromatography (TLC) methods w ere developed for the identification of deacetylasperulosidic acid in noni fruit and leaf products. TLC methods were also developed for the identification of scopoletin in noni ...

Marked variations in the vitamin C content of different varieties of apples have been observed. The values of 21 Massachusetts-grown varieties were reported by Smith and Fellers,^ and the results of several other workers have been summarized by Batchelder.^ Between different lots of apples of the same variety small differences in vitamin C concentration have been found which appeared to result ...

increasing product marketability and introduction of new cultivars for fresh consumption of apple is the world's most important breeding objectives. in this study, the qualitative and quantitative characteristics of the genotypes from cross between red spur and golab-e-kohanz apple cultivars were evaluated. a total of 19 traits including fruit attributes (firmness, fruit weight,...) and th...

Cornelian cherry is one of the most important small fruits in Arasbaran region, with wide applications in medicines and food products. In this study, the relationship among 28 quantitative and qualitative traits related to fruit, leaf, tree, and flower of 20 cornelian cherry genotypes was evaluated. Significant positive as well as negative correlations were found among some important quantitati...

in order to evaluate the effect of harvest time on fruit weight, oil content and fruit bearing in the next year in some cultivars of olive (conservalea, amygdalolia, karidolia, koroneiki, arbequina, zard and rouwghani), an experiment was performed as a split plot in time based on crd (completely randomized design) with three replications at olive research station (tarrom–zanjan) during 2013 and...

The antifungal potential of aqueous leaf and fruit extracts of Capsicum frutescens against four major fungal strains associated with groundnut storage was evaluated. These seed-borne fungi, namely Aspergillus flavus, A. niger, Penicillium sp. and Rhizopus sp. were isolated by standard agar plate method and identified by macroscopic and microscopic features. The minimum inhibitory concentrations...

The role of sucrose synthase (SuSy) in tomato fruit was studied in transgenic tomato (Lycopersicon esculentum) plants expressing an antisense fragment of fruit-specific SuSy RNA (TOMSSF) under the control of the cauliflower mosaic virus 35S promoter. Constitutive expression of the antisense RNA markedly inhibited SuSy activity in flowers and fruit pericarp tissues. However, inhibition was only ...

The rate and duration of apple fruit growth, cell division, and cell expansion, were considered in relation to within-tree factors affecting them. Fruit size at harvest was found to be related to the position of fruit on the spur, seed number, spur size, number of fruits set on the spur, and the date of flowering. The position of fruit on the spur, and spur size, were related to blossom size, b...
