Pot marigold (Calendula officinalis L.) is a medicinal and ornamental plant. The effect of different concentrations of chlormequat (cycocel), and daminozide, two plant growth retardant, on plant height, flowering, the content of essence and some other traits in pot marigold (Calendula officinalis) was assessed. Plant growth retardants are commonly applied to limit stem elongation and produce a ...

Chlormequat (cycocel or CCC), the plant growth retardant, was evaluated for its ability to control plant height in Brassica oleracea cultivar ‘Kamome White’ and ‘Nagoya Red’. Different concentrations of CCC (0, 500, 1000 and 1500 mg/L) were sprayed and drenched on plants 40 days after transplanting. Data were recorded the 60 and 90 days after transplanting. The 1500 mg/L of CCC resulted in abou...

Sclerotium cepivorum Berkleyが引き起こすネギ黒腐菌核病の防除のため，春どり作型におけるセル成型育苗トレイ灌注処理に適する殺菌剤について土壌消毒を実施しない圃場で検証した。殺菌剤はペンチオピラド水和剤，ピラジフルミド水和剤，インピルフルキサム水和剤およびマンデストロビン水和剤の合計4種類を比較した。4種類のうちピラジフルミド20％水和剤は，100倍液のセル成型育苗トレイ灌注処理によって感染，発病期間が長く，被害の最も大きい春どり作型において優れた防除効果を示した。本剤のセル成型育苗トレイ灌注処理により，ネギ茎盤部および茎盤部近傍葉鞘部では，病原菌の感染を抑制し得る十分量のピラジフルミドが感染適期に維持されていることを確認した。

Abstract Foliar diseases, like powdery mildew, septoria leaf blotch (SLB) and stem rust, affect wheat plants causing severe yield losses. Biofertilizers Pseudomonas fluorescens Migula (NRC2041) Bacillus subtilis Ehrenberg (NRC313) or the arbuscular mycorrhizal fungi Glomus mosseae Tul. & C. (NRC212A) G. fasciculatum (NRC212B) were used for soil treatment followed by foliar spray with Tricho...

Trace element malnutrition causes the development of chronic degenerative diseases. The consumption minerals and other compounds biochemical origin through intake vegetables can attenuate these deficiencies to a great extent. Because content in plant depends on conditions where it develops, there are still that should be taken into consideration. For example, Mexico, selenium does not cover rec...

Deficit irrigation is applied to several agricultural crops as a water-saving strategy. The tomato plant sensitive water stress; however, integration with biostimulant applications, based on seaweed extracts, could be strategy for plants adapting this abiotic condition. objective of study was evaluate agronomic and quality aspects cultivated under deficit combined Ascophyllum nodosum extract (A...
