In order to investigate the effect of different levels of biological fertilizers on potato performance (cv. Marfona), an experiment was carried out as strip plot based on RCB design with 3 replications in 2011 at Isfahan. Treatments included Nitrocara at 4 levels (0: control, 220, 330 and 440 ml.ha-1) as a first factor and Nitroxin+ Phosphate at 4 levels (0+0: control, 20+100, 30+150...

The effects of two diets, a control diet (commercial feed with 39% crude protein) and an experimental diet (prepared based on 42% soybean meal with 38% crude protein), on growth performance of western white shrimp (Litopenaeus vannamei) in six 0.4-ha-earthen ponds (three replications per treatment) with 25 per m2 density, were investigated. There was no significant difference in final weight (m...

Aim: Arrowroot (Maranta arundinacea L) is an underutilized tuber crop belonging to the family marantaceae. This study mainly aims evaluate different arrowroot accessions for quality starch and best yield.
 Study of Design: The field experiment was conducted in randomized block design with total ten three replications.
 Place Duration Research: present investigation undertaken at Colle...

Growing potato tubers or freshly harvested mature tubers have a dormant apical bud. Normally, this dormancy is spontaneously broken after a period of maturation of the tuber, resulting in the growth of a new sprout. Here it is shown that in in vitro-cultured growing and maturing tubers, ethanol can rapidly break this dormancy and re-induce growth of the apical bud. The in vivo promoter activity...

The effects of three harvesting dates; 120 150 and 180 days after planting (DAP) and four potassium fertilizer levels; 0, 48, 72 and 96 Kg K2O fed -1 , on vegetative growth characteristics, tuber yield potential and quality of Jerusalem artichoke (cv. Balady) were studied. Two field experiments were conducted during the two successive summer seasons of 2001 and 2002 at the Experimental station ...

Plant lipoxygenases (LOXs) are a functionally diverse class of dioxygenases implicated in physiological processes such as growth, senescence, and stress-related responses. LOXs incorporate oxygen into their fatty acid substrates and produce hydroperoxide fatty acids that are precursors of jasmonic acid and related compounds. Here, we report the involvement of the tuber-associated LOXs, designat...

The modulatory effects of the Cyclamen trochopterantum tuber extract on hepatic drug-metabolizing enzymes, including aniline 4-hydroxylase (A4H; CYP2E1), ethoxyresorufin O-deethylase (EROD; CYP1A), methoxyresorufin O-demethylase (MROD; CYP1A), caffeine N-demethylase (C3ND; CYP1A2) aminopyrene N-demethylase (APND; CYP2C6), and erythromycin N-demethylase (ERND; CYP3A1), were examined in vivo in r...
