Abstract:
... A study on the physiological and yield effects of waterlogging and the alleviation of waterlogging damage by the application of nitrogen fertilizers and mixtalol in winter rape was conducted in experimental tanks especially designed for controlling soil moisture content. The results showed that waterlogging at the seedling and stem elongation stages causes a significant decrease in nitrogen conten ...

2. Exogenous jasmonic and abscisic acids act differentially in elongating tissues from oat stem segments

Author:
Montague, M.J.

Journal of plant growth regulation 1997 v.16 no.1 pp. 11-19
ISSN:
0721-7595
Subject:
dose response; cell growth; jasmonic acid; kinetics; internodes; Avena sativa; length; abscisic acid
Abstract:
... Segments can be cut from the peduncular-1 internode of oat (Avena sativa L.) shoots so as to contain the graviresponsive, auxin-sensitive leaf sheath pulvinus, and the gibberellin-sensitive internodal tissue. These two growth-capable tissues were used to study the effects and interactions of jasmonic acid (JA) and abscisic acid (ABA) in regulating cell elongation. When supplied alone at physiologi ...

Subject:
guard cells; seedling growth; paclobutrazol; cell growth; Oryza sativa; height; plant veins; roots; starch; length; nutrient transport; chlorophyll; quantitative analysis; photosynthates; plant characteristics; translocation (plant physiology); gibberellins; stomata; chemical constituents of plants; tillers; plant morphology
Abstract:
... Paclobutrazol [(2RS,3RS)-1-(4- chlorophenyl)methyl-4,4-dimethyl-2-(1h-1,2,4-trizol- 1-yl)penten-3-ol] effectively decreased vegetative growth of rice (Oryza sativa L.) seedlings and increased the chlorophyll content. The number of veins in a leaf, the calculated number of stomata per leaf, and the length of guard cells were not altered by the paclobutrazol treatment, suggesting an effect on cell e ...

4. Inhibition of abscission of bean petiole explants by lepidimoide

Author:
Miyamoto, K.; Ueda, J.; Yamada, K.; Kosemura, S.; Yamamura, S.; Hasegawa, K.

Journal of plant growth regulation 1997 v.16 no.1 pp. 7-9
ISSN:

Subject:
dose response; abscission; allelochemicals; explants; Phaseolus vulgaris; indole acetic acid; petioles; carboxylic acids
Abstract:
... The effect of lepidimoide on the process leading to abscission was studied in bean (Phaseolus vulgaris L. cv. Masterpiece) petiole explants. The assays, involving observations on the junction of the petiole of primary leaves and the pulvinus, were conducted in the light. Lepidimoide, at concentrations of 1 micromolar or higher, delayed the abscission process; however, the progression of abscission ...

5. Dormancy implications of phosphorus levels in developing caryopses of wild oats (Avena fatua L.)

Journal of plant growth regulation 1997 v.16 no.1 pp. 27-34
ISSN:
0721-7595
Subject:
Avena fatua; seed development; dormancy; developmental stages; phosphorus; quantitative analysis; seed germination; chemical constituents of plants
Abstract:
... The element phosphorus made up 0.5% of the dry weight of dehulled Avena fatua caryopses 7 days after anthesis (DAA), half of it inorganic (Pi). Caryopses detached and pierced 7 DAA germinated in vitro with a rapid drop in Pi levels. By 15-20 DAA caryopsis dry weight had increased three- to fourfold, but phosphorus made up less than 0.04% of the dry weight of this enlarged caryopsis. Caryopses at t ...

Abstract:
... Changes in the metabolism of several types of phenolics in the pulp and pericarp of tomato (Lycopersicon esculentum) fruit var. Ailsa Craig and Pik-Red were related to the stage of development. The highest levels of chlorogenic acid were found in the pulp and pericarp at the earliest stage of fruit development, and quantities declined rapidly during fruit ripening. Levels of rutin, found only in t ...

Abstract:
... Gibberellic acid3 (GA3) modification of some growth and physiologic effects of paclobutrazol (PP333) was studied by applying PP333 alone and in combination with GA3 at the tillering stage of wheat. Results showed that GA3 weakened the effect of PP333 on tillering and shortening the plant, increased the dry matter accumulation of different tillers, improved plant nitrogen metabolism by favoring nit ...

Abstract:
... Roots of intact pea plants were treated with 2.8 X 10(-4) M Chlorsulfuron (CS). Meristematic root cells and leaf mesophyll cells were studied. Mitochondria, nucleoli, and chloroplasts were the first cell compartments to show ultrastructural disturbances. Mitochondria in treated plants had a visibly translucent matrix. The nucleoli were in the process of segregation of their fibrillar and granular ...
