Distribution Rules of Nutrients in Orobanche Aegyptiaca-Tomato Parasitic System

International Journal of Hybrid Information Technology, 2016
The research put forward the concept of parasitic system for the first time and studied distribution rules of N, P and K nutrients of different soil areas and different plant tissues in the system along with changes in the tomato growth period, as well as relevance between rhizosphere soil and nutrient contents in different plant tissues.

Host gene expression in response to Egyptian broomrape (Orobanche aegyptiaca)

Weed Science, 2004
Abstract Selective control of Egyptian broomrape is extremely difficult because the close association between host crop and parasite limits the use of most mechanical and herbicidal approaches. However, this host–parasite interaction can also form the basis of the simplest control strategy: parasite-resistant crops.

Effect of temperature on susceptibility of sunflower varieties to sunflower broomrape (Orobanche cumana) and Egyptian broomrape (Orobanche aegyptiaca)

Weed Science, 2003
Abstract Sunflower broomrape and Egyptian broomrape are two holoparasites of sunflower that cause severe yield loss. The aim of the current study was to clarify the relationship between temperature and sunflower broomrape and Egyptian broomrape parasitism of the resistant sunflower variety ‘Ambar’ (R) and the susceptible variety ‘Adi’ (S).

Composition of and changes in storage compounds in Orobanche aegyptiaca seeds during preconditioning

Israel Journal of Plant Sciences, 2002
Changes during preconditioning in the content and composition of sugars of Orobanche aegyptiaca seeds are described. Reducing sugars are rapidly utilized during the first three days of preconditioning, and remain unchanged subsequently. There is a small increase in the amount of sucrose after three days, possibly due to the operation of the glyoxylic ...

Orobanche aegyptiaca control in tomato fields with sulfonylurea herbicides

Weed Research, 1998
Field experiments were conducted from 1994 to 1997 at two locations to study the effectiveness of chlorsulfuron and triasulfuron applied through different irrigation methods (chemigation) for control of Orobanche aegyptiaca Pers. in tomato (Lycopersicon esculentum Mill). Three split applications of chlorsulfuron at 2.5 g a.i.

Production of Strigolactones by Arabidopsis thaliana responsible for Orobanche aegyptiaca seed germination

Plant Growth Regulation, 2008
The germination stimulants produced by Arabidopsis thaliana, a host of root parasitic plants Orobanche spp. but not of arbuscular mycorrhizal (AM) fungi were examined. Root exudates from the hydroponically grown A. thaliana plants were subjected to reverse phase high performance liquid chromatography (HPLC) and retention times of germination stimulants

Smoke chemicals and coumarin promote the germination of the parasitic weed Orobanche aegyptiaca

Israel Journal of Plant Sciences, 2005
The stimulation of the germination of Orobanche aegyptiaca by smoke derived from burning cellulose is described. The smoke, dissolved in distilled water, was as effective in stimulating germination as the strigol analogue GR24. High concentrations of the smoke dissolved in water were inhibitory. The putative active compound present in smoke contains an

Genetic variability of Orobanche aegyptiaca infesting tobacco in Iran by Bayesian analysis

Biologia, 2014
Broomrapes (Orobanche L.) are holoparasitic plants, parasitizing roots of a wide range of host plants. In this study, genetic polymorphism among 44 Orobanche aegyptiaca Pers. individuals collected from different regions of northwest Iran was investigated using inter-simple sequence repeat (ISSR) markers.

Biology and large scale demonstration for management of Orobanche aegyptiaca in mustard

Indian Journal of Weed Science, 2019
Field experiments to study the efficacy of neem cake, soil drenching of metalaxyl, post-emergence application of glyphosate at very low concentrations alone and in combination with 1% solution of ammonium sulphate and 125% of recommended fertility, were conducted at village Ganghala (Bhiwani) during Rabi seasons of 2014–15 and village Bidhwan (Bhiwani)

Morphogenetic regulation of seed germination in Orobanche aegyptiaca Pers.

Canadian Journal of Botany, 1977
The seed of Orobanche aegyptiaca (Orobanchaceae) is very small and contains a subglobose embryo which has not differentiated into radicle, hypocotyl, cotyledons, and plumule. Seeds were aseptically cultured to study germination and the morphogenesis of the embryo.
