Photophysiology and phytochrome content of long-hypocotyl mutant and wild-type cucumber seedlings.

Photomorphogenetic responses have been studied in a cucumber (Cucumis sativus L.) mutant (lh), which has long hypocotyls in white light (WL). While etiolated seedlings of this mutant have a similar phytochrome content and control of hypocotyl elongation as wild type, deetiolation is retarded and WL-grown seedlings show reduced phytochrome control. Spectrophotometric measurements exhibit that WL...

Photocontrol of Hypocotyl Elongation in De-Etiolated Cucumis sativus L. : Long Term, Fluence Rate-Dependent Responses to Blue Light.

Hypocotyl growth in Cucumis sativus L. cv Ridge Greenline is inhibited by increasing blue light (B) fluence rate in a near log linear fashion once a low fluence threshold is exceeded. Deviation from log linearity at the highest fluence rate used here is due to light perceived by the cotyledons and this effect is assigned to phytochrome. This response can be removed by Norflurazon treatment, wit...

Genetic Diversity and Population Structure of Cucumber (Cucumis sativus L.)

Knowing the extent and structure of genetic variation in germplasm collections is essential for the conservation and utilization of biodiversity in cultivated plants. Cucumber is the fourth most important vegetable crop worldwide and is a model system for other Cucurbitaceae, a family that also includes melon, watermelon, pumpkin and squash. Previous isozyme studies revealed a low genetic diver...

Assessment of genetic variation in cucumber ( Cucumis sativus L . ) genotypes

In this research, twenty genotypes of cucumber (Cucumis sativus) were studied that were collected from different geographical regions. The experiment was conducted as a randomized complete Block Design (RCBD) with four replications in Greenhouse. Data was collected on morphological features, yield and components of yield of cucumber which include: Total fruit yield per pickling, Fruit number pe...

Ethyl Methanesulfonate (EMS)-Mediated Mutagenesis of Cucumber (Cucumis sativus L.)

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...
