This manuscript reports that for tulip bulbs ( Tulipa gesneriana L. 'Apeldoorn'), simultaneous application of methyl jasmonate (JA-Me) with gibberellic acid (GA) increases gum formation in the bulbs, compared to JA-Me applied alone. After the dry scales of the bulbs were removed, the bulbs were treated with JA-Me and GA starting from the beginning of July 20 until November 30. Treated bulbs were stored in a laboratory room in natural light conditions. Gums produced by each treatment were weighted one month after treatment. JA-Me, at concentrations of 0.5 and 1.0% in lanolin, was applied alone, and also applied simultaneously with GA at concentrations of 0.25, 0.5 and 1.0% in lanolin. All the concentrations of GA applied simultaneously with JA-Me, substantially stimulated gum production in tulip bulbs. The production of gums decreased gradually from the beginning of October. The possible mode of action of GA to stimulate gum production in tulip bulbs is also discussed. The focus is on sugar metabolism and ethylene production.

Arsenic (As) is a potential contaminant of groundwater as well as soil in many parts of the world. The effects of increasing concentration of As (25 μM and 50 μM As2O3) in the medium on the content of starch and sugars and activity levels of enzymes involved in starch and sugar metabolism i.e. α-amylase, β-amylase, starch phosphorylase and acid invertase were studied in germinating seeds of two rice cvs. Malviya-36 and Pant-12 during 0-120 h period. As toxicity in situ led to a marked decline in the activities of α-amylase, β-amylase in endosperms as well as embryoaxes of germinating rice seeds. The activity of acid invertase increased in endosperms as well as embryoaxes whereas starch phosphorylase activity declined in endosperms but increased in embryoaxes under As treatment. In endosperms a decline in starch mobilization was observed under As toxicity, however under similar conditions the content of total soluble sugars increased in embryoaxes. The observed inhibition in activities of amylolytic enzymes might contribute to delayed mobilization of endospermic starch which could affect germination of seeds in As polluted environment, while the induced acid invertase activity and im creased sugar accumulation in embryoaxes could serve as a possible component for adaptation mechanism of rice seedlings grown under As containing medium.
