An investigation was conducted to assess proline anabolism and catabolism pathway genes under drought stress. Treatments were irrigation in three levels (25, 50 and 100% field capacity) at 1, 3, 6 and 12 d and two rose species (Rosa canina L. and Rosa damascene Mill.). The results showed that the
BACKGROUND
Rosa centifoliais commercially propagated by asexual means but in vitro propagation ensure the production of disease free and healthy plants and browning of explants creates hurdle in their multiplication.
OBJECTIVE
The aim was to reduce oxidative browning of shoots of R. centifolia in MS
Most endemic plant species have limited altitudinal ranges. At higher altitudes, they are subjected to various environmental stresses. However, these plants use unique defense mechanisms at high altitudes as a convenient survival strategy. The changes in antioxidant defense system and accumulation
Little is known about mechanisms of sweet briar adaptation to dry habitats. The species is highly invasive and displaces native plants from dry lands of the southern hemisphere. This study evaluates physiological basis of Rosa rubiginosa L. adaptation to soil drought. We performed a pot soil drought
There exist differences in the heat tolerance of Chinese rose varieties, and high temperature in summer can lead to failure of blooming in non-heat-tolerant Chinese rose varieties. We cloned a heat shock protein 70 gene (designated RcHSP70) from heat-tolerant varieties of Chinese rose (Rosa hybrida
The response of Damask rose to drought and the underlying mechanisms involved are not known. In this study, vegetative, propagated rose plants were grown under control and water-deficit conditions in a greenhouse at Taïf University, south-west of Saudi Arabia. Control plants were irrigated to field
Taking 1-year-old cuttings of a wild type and three cultivars of Rosa rugosa as test materials, this paper studied their biomass, photosynthesis, osmotic adjustment substance contents, root activity, and ion contents under the stress of different concentration NaCl. Salt stress inhibited the growth
