alstromeria is a new cut flower in iran that due to the high performance, long life, and pretty flowers and colors diversity is highly regarded. premature yellowing of leaves in cut flowersalstromeria before petal fall is the most important factor limiting the vase life of flowers. to delay leaf yellowing and increased quality, factorial experiment based on completely randomized design carried ...

Chlorogenic acid, a pharmacologically important compound, is a phenolic compound that occurs in certain commonly used medicinal herbs. We looked for the presence of this compound in the callus cultures of Varthemia persica DC (var. persica). We have evaluated the conditions for establishment of callus cultures of V. persica and the in vitro production of chlorogenic acid. Callus was initiated b...

This work describes a micropropagation protocol for plants of Cynara scolymus cv. Early French, employing cyclodextrins during the rhizogenesis stage. Shoot apices were established in basic culture medium consisting of Murashige Skoog mineral salts modified by 50% reduction in NH4NO3 and KNO3, Heller's micronutrients, Gamborg's vitamins, 100 mg l ÿ1 myo-inositol, 30 g lÿ1 saccharose and 8.0 g l...

delaying bud break, using chemicals is an approach to avoid spring frost damage. therefore, the effect of spraying different concentrations of soybean oil and naphthalene acetic acid (naa) on delaying bud break, altering internal atmosphere and cold hardiness in grape cultivar ‘fakhri’ was studied in 2011 in a commercial vineyard in maryanaj, hamedan using a factorial trial based on randomized ...

Stevia rebaudiana Bertoni that conventionally propagated by seed or by cuttings or clump division which has a limitation of quality and quantity seed material. In present study, callus culture technique was tried to achieve rapid plant multiplication for quality seed material. Callus induction and multiplication medium was standardized from nodal as well as leaf sagments. It is possible to main...

Dillenia pentagyna belongs to family Dilleniaceae, is commonly known as Karkat. It is small deciduous tree reaching up to the height of 10-12 m with a straight bole. The species is distributed throughout in India including Andaman & Nicobar. It is highly important medicinal tree species. Its leaves, fruits and bark show antibacterial, antialpha glucosidase and antioxidant property. Due to its h...

An efficient plant regeneration method was established for Caesalpinia bonduc (L.) Roxb. by culturingimmature epicotyl explants. Morphogenic calli were initiated from 96% of epicotyl explants on MS mediumsupplemented with BA (6-benzylaminopurine) 4.0 mg/l and NAA (Naphthalene acetic acid) 1.0 mg/l. The calliformed were excised and subcultured on MS medium fortified with 1 mg/l...
