Verticillium dahlia Kleb. is a soil-borne pathogen which causes worldwide economically important plant and yield losses. So far no resistance preventing the fungus from growing in the plants could be found in the genus Fragaria. But there are cultivars with different levels of tolerance. In particular after the ban on chemical control with effective soil disinfectants (methylbromid) cultivation...

Rates of nitrogen application were studied in relation to commercial yield and fruit quality of cucumber plants (Cucumis sativus L. cv. Bunex). All plants were grown under controlled conditions in a greenhouse. Treatments consisted of the application of N as KNO3 (N1, 2.5 g m-2; N2, 5 g m-2; N3, 10 g m-2; N4, 20 g m-2; and N5, 40 g m-2). The fruits of cucumber from the N3 and N4 treatments were...

Efficacy against the sweetpotato whitefly (SPWF) Bemisia tabaci (Gennadius) of an insecticidal soap, two horticultural oils (one vegetable and the other petroleum based) and 15 detergents was evaluated under greenhouse conditions. Applications were directed to the underside of infested zucchini squash, tomato, or poinsettia leaves. Live nymphs were distinguished by their ability to deposit hone...

Reclaimed wastewater is an important source of irrigation in semiarid and arid zones. Here we report data on carbamazepine (CBZ) uptake by cucumber plants in hydroponic culture and greenhouse experiments using different soil types irrigated with fresh water or reclaimed wastewater. Data obtained from the hydroponic culture experiments suggest that CBZ is mainly translocated by water mass flow, ...

The possible involvement of polyamines (PAs) in the chilling tolerance of cucumber (Cucumis sativus L. cv Jinchun No. 3 and cv Suyo) was investigated. Plants with the first expanded leaves were exposed to 3 degrees C or 15 degrees C in the dark for 24 h (chilling), and then transferred to 28 degrees C/22 degrees C under a 12-h photoperiod for another 24 h (rewarming). Chilling-tolerant cv Jinch...

BACKGROUND Pythium ultimum is a plant pathogen that causes significant yield losses on many economically important crops. Chemical treatment has been used for disease control. In searching for alternatives, venom piperidine and piperideine alkaloids from red imported fire ants were tested against P. ultimum in vitro, and piperideines were employed to control cucumber damping-off in the greenhou...

The study was carried out with 38 collected garlic (Allium sativum L.) cultivars from 3 important garlic production area in Iran (Zanjan, Hamadan and Mazandaran). The cloves were planted in 30 × 30 cm pots in control conditions (average temperature: 20 °C and 60 % RH). Randomized complete block design with 3 replications was conducted. The bulbing characteristics such as bulb weight, bulb circu...

The creation of a special environment for the enhancement of plant growth, outside the normal growing season, dates back to 500 B.C. The Gardens of Adonis, in ancient Greece, saw the first application of covering and protective materials to foster the growth and propagation of ornamental flowers. Another historical milestone occurred when Tiberius Caesar instructed his gardeners to provide a su...
