background & aim: aloe vera is used in the food and pharmaceutical as an aid to effective treatment. the purpose of this study is to improve growth, increase production of valuable metabolites and increase the sugars in aloe vera gel with low cost and high efficiency under water stress conditions. experimental: in this study, aloe vera potted in greenhouse conditions with four levels of zeo...

BACKGROUND AND AIMS Ageing effects may be due to dysfunction leading to decreasing reproduction and survival with age. In plants, however, other (physiological) causes, associated with size for example, may also play a role. Iteroparous plants with genetically variable life spans can be helpful in unravelling these two aspects of changes associated with growing older. METHODS In a long-term e...

important cut flowers in tropical and sub tropical areas of the world and has the seventh rate of production between all cut flowers of Iran. In order to investigate different effects of storage temperatures (8 weeks at 4 °C, 4 weeks at 4 °C + 4 weeks at 20 °C, 8 weeks at 12 °C, 4 weeks at 12 °C+ 4 weeks at 20 °C and 8 week at 20 °C) and different concentrations of gibberellic acid (0, 150 and ...

Since the biological effects of maleic hydrazide (MH) were first described by SCHOENE and HOFFMANN (4), a great many papers have appeared describing the effects of that compound on growth and flowering. NAYLOR (3) sprayed tobacco, maize and cocklebur with various concentrations ranging from .025% to .2%o and obtained either suppression or delay of visible flowering. WHITE and KENNARD (5) delaye...

Tulip is one of the most important bulbous genera in world’s floriculture. It known that cold exposure bulbs before planting required to break bulb dormancy and promote plant’s flowering. Preparation procedures performed by breeders differ duration thermal level, choice procedure depends on genotype’s sensitivity temperature; however, little about metabolic responses underlying different behavi...

background due to danger of spillage of cyst materials during surgery, chemoprophylaxis is routinely recommended for cyctic echinococcosis. however, for prophylactic purposes the time for starting and the duration of administration of prophylactic drug regimen is not yet clear. the aim of the present study was to evaluate the chemoprophylactic efficacy of one month administration of albendazole...

Three-year field trials were set up on eutric brown soil in northwestern Croatia (Zagreb) with the objective to determine the effect of plant density and nitrogen rates on the formation and size of leaf area of seed sugar beet, and on the yield and seed quality in seed production without transplanting. Investigations should also reveal how much the yield and quality of sugar beet seed depend on...
