Rosa hybrida L. is an important commercial cut flower. Salicylic acid (SA) and calcium chloride (CaCl2) act as endogenous signal molecules responsible for growth parameters in plants. The aim of this study was to evaluate the effects of preharvest SA and CaCl2 treatments in extending the vase life of cut rose flowers. Therefore, a factorial experiment based on completely randomized design with ...

Genetic improvement of flower vase life is an important breeding target for ornamental plants. As the cut dahlia (Dahlia variabilis) flowers very short, we initiated a conventional crossbreeding research program in 2014 to improve it. We evaluated seedlings during summer (from July early September) develop dahlias that grow and bloom under high temperatures have excellent Japanese conditions. C...

Alstromeria is a new cut flower in Iran that due to the high performance, long life, and pretty flowers and colors diversity is highly regarded. Premature yellowing of leaves in cut flowersAlstromeria before petal fall is the most important factor limiting the vase life of flowers. To delay leaf yellowing and increased quality, factorial experiment based on completely randomized design carried ...

The effect of exogenous salicylic acid (SA) on the vase life of cut rose flowers was investigated. ‘Yellow Island’ roses were obtained from a commercial grower. The roses were pulse treated with SA (0, 50, 100, 150, 200 mg l) for 18 hours. Compared to the control treatment (DW), the greatest delay in senescence was obtained in cut roses treated with 150 mg l SA. With this treatment, flower vase...

Wood vinegar is a substance, derived from cooling black carbon fire, which could be used instead of chemical materials in the agriculture industry as an organic compound. In order to study the effectiveness of pine wood vinegar on physiological and photosynthesis traits of cucumber, two experiments were conducted based on a completely randomized design with six treatments including 0, 1250, 200...

tuberose (polianthes tuberosa l.) is an important commercial cut flower that has a short vase life. an experiment was carried out by using five different levels of humic acid (ha) (0, 25, 50, 75, and 100 mg l-1) and seven different levels of silver nano-particles (snp) (0, 0.5, 1, 2, 3, 4 and 5 mg l-1) mixed with 1.5% sucrose on cut tuberosa cv. single flower. the loss of fresh weight on third ...

In this paper Shannon-Weaver (SI-3.58-4.07, SII-3.1-3.72, SIII-1.64-2.25, SIV-2.54-2.95 and SV-3.09-3.23) diversity index was applied to surface phytoplankton to study the water quality status of river Bhadra receiving Mysore paper mill and Iron and steel mill effluent. A total of 45 species of phytoplankton belonging to 5 classes were recorded and study indicated that the phytoplankton diversi...
