Combined spraying of gibberellin (GA) and prohydrojasmon (PDJ) was an effective method to prevent the physiological disorder peel puffing in citrus fruit. However, GA PDJ combined treatment inhibited carotenoid biosynthesis during fruit ripening process, which led mature with poor color. In present study, improve coloration PDJ-treated fruit, effects postharvest treatments two auxins, indole-3-...

The present study was carried out to investigate laboratory germination responses of six collections of Garcinia kola seeds to six different hormonal pre-germination treatments. This consisted of soaking seeds for three days in cool distilled water (control), in cool distilled water supplemented with 10 M of either naphthaleneacetic acid (NAA), 2,4-dichlorophenoxyacetic acid (2,4-D), benzylamin...

In order to improve the resistance of apples stresses (abiotic stresses) during hot and dry summers enhance their productivity marketability, Anna apple trees were treated with aminoethoxyvinylglycine (AVG), 1-methlcyclopropene (1-MCP), naphthalene acetic acid (NAA), alone, or in combination, two successive seasons. All treatments significantly increased yield per tree, average fruit volume, di...

BACKGROUND Aloe vera L. is an important pharmaceutical plant from which several medicinal and cosmetic compounds are extracted. Aloe is naturally propagated through offset, which is a slow and expensive labor cost method with low economical income. OBJECTIVES In this study, the effect of different media on shoot proliferation of the shoot tip of Aloe vera L. was investigated. MATERIALS AND ...

Abstract The present experiment was conducted to determine the effect chemical fertilization rates and foliar application of plant growth regulators PGRs (Kinetin or Napthaleneacetic Acid (NAA) their interactions on growth, flowering, composition Ervatamia coronaria plants. plants were fertilized monthly with NPK at rate 2, 4 6 g pot-1, in addition control Plants received treatments sprayed eit...

In order to evaluate the different concentrations of Naphthalene Acetic Acid (NAA) on alternate bearing of ‘Siahoo’ mandarin (Citrus reticulata Blanco) was performed an experiment as factorial arrangement in randomized complete block design with two factors. First factor was spray time (30 or 50 days after flowering) and different concentration of NAA (0, 200, 300 and 400 mg/L) with three repli...

 Stevia rebaudiana Bert (Asteraceae) is herbaceous plant with sweet leaves, which are the source of sweetener products. The present study focuses on effects of different combination of plant growth regulators on callus induction, callus cell growth and regeneration and volatile constituents from callus of stevia in tissue culture condition. The results of present study showed callus formation p...

This experiment was performed to optimize the medium for tissue culture of Taraxacum kok-saghyz Rodin. Different tissue culture approaches such as shoot regeneration from seed, callus formation from leaf explants and plant regeneration from callus were investigated in this study. All the explants were cultured on MS basal medium supplemented with 20g/l sucrose, 7g/l agar and different plant gro...

suckers are strong sinks of water and nutrients, thus they have intensive competition with plant vegetative parts like scion of budded seedlings. this is an enormous problem of citrus nurseries in north of iran. as far as vast input and time is spending on control of these unwanted suckers. this research, that carried out in design, compares 10 different sucker control methods in three citrus r...
