In the present study, dormancy and germination requirements were investigated in seeds of Citrullus colocynthis (L.). Seeds were subjected to 10 pretreatments in the present study.  These pretreatments included hot water (100° C) followed by the seeds placed between double layered filter paper moistened with 5 ml of distilled water and kept at 28 - 30 °C, sulphuric acid (98% v/v), for 30 min fo...

the effects of the plant growth promoter gibberellic acid (ga3) and plant growth retardant chlormequat chloride (ccc) on biomass and quality of angelica dahurica var.formosana plants were investigated employing physiological and biochemical methods. plants were sprayed with ga3 or ccc at rosette stage and coumarin content was analyzed by high performance liquid chromatography (hplc) after harve...

tuberose is one of the most important floral crops in iran. long spikes of fragrant flowers make it excellent for cut flower. due to the beauty and sweet fragrance of flowers, it used in all seasons for flower arrangements. production of high quality flowers and vase life extension is important for competition in world markets. for this reason this research was conducted on polianthes tuberosa ...

in order to study the effects of cppu and ga3 on fruit quality and quantity of sultanina grapes, a factorial experiment in a randomized complete block design was implemented in a commercial vineyard near bonab city (west azerbaijan province). the spraying was done at fruit set stage using cppu and gibberellic acid. according to the results, it was found that these plant growth regulators had a ...
