some crops have been observed to posses effects of allelopathic type. it would be interesting and useful as well to study these plants' allelopathic effects on other crop plants, particularly in rotation and intercropping. so, in this study, the allelopathic potential of cucumber organs' extract on seedling growth of cucumber, eggplant, pepper, and tomato was evaluated using a randomi...

the development of seminal and lateral root system plays a major role in plant access to water and nutrients under abiotic stress, especially salinity. in order to understand the relation between root growth responsesand shoot physiological indices oftwo bread wheat cultivars contrasting in salt tolerance (kavir and shiraz), a greenhouse experiment was conducted with two salinity levels (0 and ...

In a pot culture experiment, the root length density, potassium concentration in crop, and total K uptake by wheat (Triticum aestivum var. HD 2285) at different growth stages (CRIS-Crown Root Initiation Stage, MTS-Maximum Tillering Stage, FLS-Flag Leaf Stage and DFS-Dough Formation Stage) were determined. Wheat crop was grown in 72 pots containing 4.5 kg of three types of soils, namely Alfisol,...

abstract several root measuring methods have been developed until now but there is no single method of root measurement applicable for all situations. this study was conducted to evaluate the effects of a single trinexapac-ethyl (te) and paclobutrazol application on kentucky bluegrass root growth under three irrigation treatments. evaluating of root length density (rld), root surface area (rs) ...
