IN VITRO CLONAL PROPAGATION OF ONION (ALLIUM CEPA L.) THROUGH SHOOT TIP CULTURE

نویسندگان

چکیده

The aim of the present investigation was to standardize in vitro shoot tip culture technique considering various aspects for direct plant formation two onion (Allium cepa L.) varieties ‘Indian’ and ‘Taherpuri’. About 1.5-2.2 mm tips were collected from bulbs sterilized with 0.1% HgCl2 duration. Then they cultured on MS medium supplemented hormonal concentrations different media composition primary establishment. BAP 1.5 mg l-1 + NAA1.0 found be best formulation establishment tips. Primarily established further multiplication, 2ip 2.0 NAA 0.5 most effective multiplication. highest percentage shootlet produced root MS+2.0 IBA both cultivars (Taherpuri 90% Indian 80%). plantlets transferred small pots containing soil : sand 1:1 kept under shade covered perforated polythene sheet. After proper hardening field.

NUTRIENT DIAGNOSIS ( CND ) OF ONION ( Allium cepa L . )

Nutritional constraints often restrict yields of crops in farmers’ fields. Plant nutrient status is currently diagnosed using empirically derived nutrient norms from arbitrarily defined high and low yielding subpopulations above a quantitative yield target. Generic models can assist Compositional Nutrient Diagnosis (CND) in providing a yield cutoff value between high-and lowyielding subpopulati...

Determination of antidiabetic activity in Allium cepa (onion) tissue cultures.

Seedling, seedling parts and callus cultures of onion were tested for their antidiabetic activity by feeding the tissue-extracts to diabetic rats. The results indicated much higher antidiabetic activity in callus cultures as compared to natural bulbs of onion. These results may be of pharmaceutical significance since the callus can be used as an alternative source for the isolation of antidiabe...
