in this study, the susceptibility of twenty-nine tomato varieties to broomrape infection under glasshouse conditions was investigated. results showed that differences in susceptibility to infection were significant among tomato varieties. significant differences were in number and time of broomrape shoots emerging, broomrape dry weigh (shoots and tubercles) and growth and fruit yield of tomato....

In plants, carbon source-sink relationships are assumed to affect their reproductive effort. In fruit trees, carbon source-sink relationships are likely to be involved in their fruiting behavior. In apple, a large variability in fruiting behaviors exists, from regular to biennial, which has been related to the within-tree synchronization vs desynchronization of floral induction in buds. In this...

The Vaccinium genus contains several valuable fruit and ornamental species, among others: highbush blueberry (Vaccinium × corymbosum L.), cranberry (Vaccinium macrocarpon Ait.), and lingonberry (Vaccinium vitis-idaea L.). In some most popular and valuable cultivars, the conventional propagation methods, exploiting hard or soft wood cuttings, are inefficient. The demand for nursery plants could ...

An aqueous extract of the shade-dried parts Asparagus aethiopicus L. and densiflorus (Kunth) Jessop was used to synthesize copper (CuO) nanoparticles (Cu NPs). UV-visible spectroscopy performed assess formation Cu NPs. Maximum absorbance obtained between 310–360 nm, confirming CuO NPs were effective against Pseudomonas aeruginosa (ATCC 27853), a gram-negative human pathogenic bacterium. The bac...

a total of twenty seven bacterial strains were isolated from cankerous tissues of apricot, nectarine, peach, plum, sour cherry and sweet cherry trees in tehran province and identified as pseudomonas syringae pv. syringae (pss), the causal agent of the bacterial canker disease, on the basis of lopat (levan production, oxidase test, potato rot, arginine dihydrolase and tobacco hypersensitive ...

The response of apple cultivars to powdery mildew attack – Podosphaera leucotricha (Ell. et Everh.) Salm. – on leaves and shoots, for seven years (1990-1996), emphasised a large variability for this character existing within 75 apple varieties tested in an experimental field at the Fruit Research Station in Cluj-Napoca, Central Transylvania, Romania. The experimental results confirmed that the ...

Inflorescence development of the 'Hass' avocado (Persea americana Mill.) was investigated at the macro and microscopic level. Near the end of shoot extension, two secondary axis meristems were present in the axils of inflorescence bracts. The primary axis meristem changed shape from conical to flattened to conical followed by the initiation of additional bracts and associated secondary axis inf...

Fruit flies were obtained from 13 species of naturally infested fruits in the central region of Tocantins State, from January to October 2005. A total of 1,753 female flies were collected that belong to 11 species: Anastrepha coronilli Carrejo & González, A. fraterculus (Wied.), A. mucronota Stone, A. obliqua (Macquart), A. sororcula Zucchi, A. striata Schiner, A. turpiniae Stone, A. zenildae Z...
