drought, as an abiotic stress inflicts destructive and harmful effects on plants at their different growth stages. plants react differently to drought. among their reactions is the production of such osmolytes as proline and glycine betaine. it seems that, through exogenous application of these materials, plant resistance to drought stress can be increased. therefore, a factorial experiment, ba...

this study was carried out to investigate impacts of myrobalan rootstock and blackthorn interstem on fruit growth, physico-chemical features and bioactive compounds of two apricot cultivars (‘harcot’ and ‘roksana’) in 2010 and 2011. fruits of both cultivars on myrobalan and/or blackthorn grew with a classic double sigmoid curve from full bloom time to harvest. during growth and development peri...
