Isolation and identification of Desmodium root exudates from drought tolerant species used as intercrops against Striga hermonthica
Plants from the genus Desmodium, in particular D. uncinatum, are used on sub-Saharan small-holder farms as intercrops to inhibit parasitism of cereal crops by Striga hermonthica and Striga asiatica via an allelopathic mechanism. The search for Desmodium species which are adapted to more arid conditions, and which show resilience to increased drought stress, previously identified D. intortum, D....
متن کاملDrought-tolerant Desmodium species effectively suppress parasitic striga weed and improve cereal grain yields in western Kenya
The parasitic weed Striga hermonthica Benth. (Orobanchaceae), commonly known as striga, is an increasingly important constraint to cereal production in sub-Saharan Africa (SSA), often resulting in total yield losses in maize (Zea mays L.) and substantial losses in sorghum (Sorghum bicolor (L.) Moench). This is further aggravated by soil degradation and drought conditions that are gradually beco...
متن کاملExploiting phytochemicals for developing a 'push-pull' crop protection strategy for cereal farmers in Africa.
Lepidopteran stemborers and parasitic weeds in the genus Striga are major constraints to efficient production of cereals, the most important staple food crops in Africa. Smallholder farmers are resource constrained and unable to afford expensive chemicals for crop protection. Development of a push-pull approach for integrated pest and weed management is reviewed here. Appropriate plants were di...
متن کاملIdentification of Drought Tolerant and Sensitive Species of Thyme through Some Physiological Criteria
Drought as the most important abiotic stress has deleterious effects on plants. Developing drought tolerant varieties can help produce plants in a sustainable way. This study was conducted to identify drought tolerant and drought sensitive thyme species including Thymus vulgaris, T. vulgaris (origin: Spain), T. carmanicus, T. daenensis and T. kotschyanus and to study the mechanism used by them ...
متن کاملIsolation and Identification of Calystegines in Root Cultures of four Physalis Species
Calystegines were isolated from the root cultures of Physalis divaricata, P. pubescens, P. philadelphia,and P. philadelphia (solanaceae). Calystegines of P. divaricata were identified as calystegine A3, A5, B1 and B2, with concentrations of 6.99, 4.41, 8.52, and 14.7 ?g/g in fresh mass, respectively. Root cultures of P.pubescens contain calystegine A3, B1 and B2, P. philadelphia only contains ...
