Stirring largely eliminated the greater effectiveness of Carbowax 6000 compared to mannitol in reducing cucumber (Cucumis sativus L.) hypocotyl section elongation. Stirring increased elongation in water but reduced elongation in growth regulator solution. Shrinkage of cells without plasmolysis in hypertonic Carbowax solutions indicates that Carbowax 6000 did not penetrate cell walls. Sections p...

Introduction In Italy, grasspea (Lathyrus sativus L.) is one of the least common grain legumes. Today, it is not included in the official statistics of Italy and its survival is due to the praiseworthy action of a small number of farmers in very limited areas of peninsular and insular centralsouthern Italy. Since the Second World War the sharp reduction in cultivation, similarly for other grain...

1-Aminocyclopropane-1-carboxylic acid (ACC) level, ACC synthase activity, and ethylene production in cucumbers (Cucumis sativus L.) remain low while the fruit are held at a temperature which causes chilling injury (2.5 degrees C) and increase rapidly only upon transfer to warmer temperatures. The increase in ACC synthase activity during the warming period is inhibited by cycloheximide but not c...

Ethyl methanesulfonate (EMS) is a stable and effective chemical mutagen. In this study, cucumber (Cucumis sativus L. cv. “Shannong No. 5”) seeds were treated by 1% EMS for 12 h, 24 h and 48 h to optimize EMS mutagenesis and determined median lethal dose of EMS (1% EMS and 24 h) for “Shannong No. 5”. After treated by 1% EMS for 24 h, 541 M1 plants were grown in greenhouse for phenotype investiga...

Isolations of polymorphic sequences of two pairs of the NIL lines of cucumber (Cucumis sativus L.), which differ with respect to sex, were carried out using the subtraction hybridization methods of DSC (Differential Subtraction Chain) and GDDSC (Genetically Directed DSC). 266 DSC tags were isolated from the entire genome region, and 38 GDDSC tags were isolated from the region containing the sex...

PIWOWARCZYK BARBARA, PINDEL ANNA, MUSZYŃSKA EWA. 2016. Callus Induction and Rhizogenesis in Lathyrus sativus L. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(1): 123–128. Grass pea (Lathyrus sativus L.) is a leguminous plant distinguished by great resistance to abiotic and biotic stresses that can become a valuable source of protein feed in the nearest future. Howev...

From ancient times, the saffron Crocus sativus L. is widely used as drug to promote health and fight disease, especially in the Middle East and Southeast Asia. Saffron is cultivated in different parts of the world, but currently mainly in Iran. In view of its wide range of medical uses, the saffron has under gone extensive phytochemical and biochemical studies and variety of biologically active...

Reciprocal cleft and pistillate floral bud grafts were made between parthenocarpic ;Fertilla' and nonparthenocarpic ;MSU 713-5' cucumber (Cucumis sativus L.) lines to localize the site for stimulation of parthenocarpic fruit set. No fruit set on ;MSU 713-5' controls, scion grafted to ;Fertilla,' or rootstock with ;Fertilla' as the scion. ;Fertilla' controls, rootstock, and scions all produced p...

The formation of protochlorophyllide and protochlorophyllide phytyl ester was investigated during etioplast biogenesis in order to study the biosynthetic relation of these two compounds. Protochlorophyllide accumulates slowly during the first 2 days of germination, its rate of formation increases sharply during the 3rd day, and then it decreases. Protochlorophyllide phytyl ester starts accumula...

Cilj istraživanja bio je utvrditi alelopatski potencijal lucerne (Medicago sativa L.) na klijavost sjemena i rast klijanaca rotkvice (Raphanus sativus L.), radiča (Cichorium intybus L. var. foliosum) rajčice (Lycopersicon esculentum Mill.). Vodeni ekstrakti pripremljeni od suhe nadzemne mase u tri koncentracije (1 %, 2,5 % 5 %) testirani su laboratorijskim uvjetima. Alelopatski ovisio o test vr...
