Catalase activity in grapevine (Vitis vinifera L.) buds cv. ;Perlette.' increased to a maximum in October and thereafter decreased within 3 months to less than half its maximal rate. The decrease in catalase activity coincided with the decline in temperature during winter. The rate of sprouting of buds forced at 23 degrees C was negatively related to the activity of catalase. Artificial chillin...

one of the most effective ways to propagate lilium is by using tissue culture techniques, preferably through bulblet production. in addition to the surviving percentage of lilium bulbs after transplantation, the small size of in vitro bulblets compared to commercial bulbs and bulblets‟ dormancy are the most important constraints to commercializing lilium micropropagation. different concentratio...

dormancy breaking of field maple (acer campestre l.) seed, by gibberllic acid (ga3) at 0, 250, 500 and 1000 ppm in 24 and 48 hours and stratification treatments in moist sand under warm (18-20 °c) and cold (2-4°c) conditions were investigated. effects of ga3 and stratification and their interaction on germination percent (gp) and germination speed (gs) were significant. the highest gp occurred ...

nowadays, in many rangelands, due to over grazing, and problems that some plantshave in germination, the rate of forage production is greatly reduced. so to take advantages ofthe benefits of such plants, it is necessary to identify and remove barriers of germination andestablishment of suitable plants. the present study was designed to investigate differenttreatments of breaking dormancy and st...

ferula assa-foetida l. (apiaceae) is one of the most important endangered medicinal plants,which is rare in nature due to poor seed germination. in an effort to improve and promote the cultivation ofthis plant, the effects of two temperatures (23°c and 4°c), exogenous ga3 and cytokinins (kinetin and bap)were investigated on dormancy breaking and germination of f. assa-foetida l. seeds. among th...

Dormancy inhibits seed and bud growth of perennial plants until the environmental conditions are optimal for survival. Previous studies indicated that certain co-regulation pathways exist in seed and bud dormancy. In our study, we found that seed and bud dormancy are similar to some extent but show different reactions to chemical treatments that induce breaking of dormancy. Whether the abscisic...
