A straightforward and reliable method was developed for the determination of chlormequat in pears by liquid chromatography/mass spectrometry (LC/MS). Water and methanol were compared as extraction solvents. Because no significant differences in extraction efficiency or repeatability were found, water was chosen as the extraction solvent. The extracts were analyzed without cleanup by either an i...
Production of herbaceous perennials has been one of the most rapidly growing areas of floriculture for the last 8 to 10 years. However, greenhouse and nursery production of herbaceous perennials requires a significant effort to control the growth of some of these very vigorous plants. Until very recently the primary methods of control were scheduling and pruning. If a grower missed the target d...
we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...
Two experiments were conducted under field and greenhouse conditions, to investigate the effect of herbal spraying chlormequat chloride (CCC) (0 and 2.5 g. L-1), soil incorporation of Zinc sulfate (Zn) at the three rates of 0, 25 and 50 kg ha-1, and pre-treatment of seeds with bio-fertilizer Nitroxin (Nit) in a randomized complete block design with a factorial arrangement and three replications...
When embryonated and de-embryonated cotyledons of cowpea (Vigna unguiculata L.) were kept for germination, only embryonated cotyledons (EC) developed into seedlings. alpha-Amylase activity appeared late in de-embryonated cotyledons (DEC), but increased and matched with that of EC on 4th day, and thereafter started declining. A higher content of reducing sugars may be one of the factors in down ...
