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...
متن کاملLocalization of Stem Elongation Control in Cucumis sativus L.
Reciprocal grafts, and applications of gibberellin (GA) and indoleacetic acid (IAA) were used to localize the site of control for stem elongation in cucumber (Cucumis sativus L.). Dwarf and tall plants were reciprocally grafted to determine influence of stems and roots on stem elongation. At 21 days there were no significant differences in length between stems grafted to their own roots and tho...
متن کاملAuxin transport is required for hypocotyl elongation in light-grown but not dark-grown Arabidopsis.
Many auxin responses are dependent on redistribution and/or polar transport of indoleacetic acid. Polar transport of auxin can be inhibited through the application of phytotropins such as 1-naphthylphthalamic acid (NPA). When Arabidopsis thaliana seedlings were grown in the light on medium containing 1.0 microM NPA, hypocotyl and root elongation and gravitropism were strongly inhibited. When gr...
متن کاملAssessment 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...
متن کاملInheritance and quantitative trait locus analysis of low-light tolerance in cucumber (Cucumis sativus L.).
The low-light tolerance index was investigated in a set of 123 F2:3 lines during the seedling stage across 2 seasons, and the heredity of low-light tolerance was assessed via different ge-netic analysis methods. The results of the classical analysis showed that low-light tolerance is controlled by an additive-dominant poly-gene, and the polygenic inheritance rate of separate generations was >30...
