effects of gibberellic acid and gold light on germination, enzyme activities, and amino acid pool size in a dwarf strain of watermelon.	gibberellic acid (ga(3)) promotes and continuous gold light inhibits germination of seeds of a dwarf strain (wb-2) of watermelon [citrullus lanatus (thunb.) matsu. and nakai]. osmotic inhibition of germination with mannitol in light-grown seeds of wb-2 was only slightly reversed by ga(3) at the concentrations used, whereas, ga(3) substantially relieved osmotic inhibition in dark-grown seeds.the effects of ga(3) and gold light on development of catalase and invertase activities and on levels of f ...	1978	16660470
genetics of seed-coat colour in citrullus lanatus (thunb.) mansf.	intervarietal crosses in watermelon, citrullus lanatus (thunb.) mansf., involving six parents with black (j18-1 and j 75), brown (j56-1 and n.h. midget), red (bykovski-199) or light cream (red nectar) seed-coat colour were made. parents, f1, f2 and backcross populations were evaluated for their phenotypic expressions with regard to the seed-coat colours involved. black colour was monogenically dominant over brown light cream and red colour of seed-coat separately or independently. red colour was ...	1978	24311206
interaction of ethylene and a cytokinin in promoting hypocotyl elongation in a dwarf strain of watermelon.	experiments were conducted to study the interaction of ethylene and the cytokinin n(6)-benzyladenine (ba) in promoting hypocotyl elongation in a dwarf strain of watermelon (citrullus lanatus [thunb] matsu. and nakai). optimum promotion of hypocotyl elongation is elicited by an apical treatment with 0.2 microgram ba. at dosages above 0.3 microgram per apex, ba-enhancement of elongation is reduced concomitant with stimulation of ethylene production and lateral expansion of hypocotyls. application ...	1981	16662017
effect of water stress on the carbohydrate metabolism of citrullus lanatus seeds during germination.	gluconeogenesis in citrullus lanatus seeds is a post germinative event. increases in isocitrate lyase activity and incorporation of radioactivity from [2-(14)c]acetate into sugars occur only after radicle emergence. during germination, the seeds appear to rely on carbohydrate as the respiratory substrate. at this time, glycolysis, the pentose phosphate pathway, and the tricarbocyclic acid cycle seem to be functional. utilization of raffinose during germination appears to be important.water stres ...	1985	16664032
effects of allelopathic compounds of corn pollen on respiration and cell division of watermelon.	the effects of the allelopathic compounds of an "'ethanolic extract" of corn pollen on growth, respiration, and cellular division of watermelon (citrullus lanatus, var. peacock improved) were studied. bioassays with the ethanolic extract showed an inhibition of radicle and hypocotyl growth. the effects on respiration were observed in isolated watermelon hypocotyl mitochondria. the ethanolic extract acts as an inhibitor of the electron pathway, decreasing oxygen consumption in state 3, with malat ...	1988	24276995
control of pyrophosphated-fructose-6-phosphate 1-phosphotransferase activity in the cotyledons of citrullus lanatus.	after initiation of radicle elongation, the pyrophosphate:d-fructose-6-phosphate 1-phosphotransferase (pfp) activity sharply increases in the cotyledons of citrullus lanatus. removal of the radicle early during incubation prevents the increase in pfp activity in the cotyledons evident in the control. removal of the radicle at any stage after germination results in a decrease in pfp activity in the cotyledons. application of kinetin (0.5 micromolar) or 2-chlorophosphonic acid (0.1 micromolar) to ...	1990	16667523
pyrophosphate dependent phosphofructokinase of citrullus lanatus: molecular forms and expression of subunits.	during germination and seedling establishment, the total pyrophosphate-dependent phosphofructokinase (pfp) activity in the cotyledons increases. two types of subunits with molecular weights of 68 (alpha-subunit) and 65 (beta-subunit) kilodaltons are present. the increase in activity coincides with an approximately 10-fold increase in beta-subunit and twofold increase in alpha-subunit content. different isoforms of pfp are present at all stages of incubation, but the ratio between the isoforms si ...	1991	16668318
induction of pyrophosphate-dependent phosphofructokinase in watermelon (citrullus lanatus) cotyledons coincides with insufficient cytosolic d-fructose-1,6-bisphosphate 1-phosphohydrolase to sustain gluconeogenesis.	during germination of citrullus lanatus, pyrophosphate-dependent phosphofructokinase (pfp) activity is induced. the peak of pfp activity coincides with the maximum gluconeogenic flux and high fructose-2,6-bisphosphate (fru-2,6-p2) concentrations. determination of cytosolic fructose-1,6 bisphosphatase (fbpase) activity in crude extracts is unreliable because of the high pfp activity. the fbpase activity, after correction for the contaminating pfp, is only one-third of the pfp activity. purified c ...	1993	12231792
