This experiment was conducted to study the effects of application of partial root zone drying technique on quantitative and qualitative characteristics of strawberry (Fragaria ananassa cv. Selva). The experiment was arranged as randomized complete blocks design with five treatments and four replications. One week after planting the seedlings, different irrigation regimes including FC: FC (moist...

Effect of gibberellic acid on marigold (Calendula Officinalis L.) was evaluated in a pot culture experiment. A factorial experiment based on completely randomized design including 12 treatments and four replications was carried out. Main factor was foliar application stages (first, second and third) and sub factor included different concentrations of GA3 (0, 50, 150 and 250 mg L...

The aim of this study was measuring nitrate and leaf chlorophyll content in aerial parts of plant, from which we can predict the hypocotyl nitrate content of radish. A factorial experiment in a completely randomized design with five replicates was carried out on two varieties of radish (Cherry Belle and Sparker). Plants were grown in perlite containing pots and were treated with five levels of ...

The ch4 mutant of sweetclover (Melilotus alba) has previously been demonstrated to be temperature- and photoperiod-sensitive for the accumulation of chlorophyll. Pigment content of ch4 mutant leaves was examined as a function of trifoliolate mass, an index of leaf development. Inhibition of chlorophyll accumulation caused by increased growth temperature or decreased photoperiod can be attenuate...
