Gibberellic acid induces (a) increased elongation of Avena sativa stem segments, (b) increased formation of cell wall material, measured on the basis of dry weight, and (c) increased incorporation of (14)C-glucose into all fractions of the cell wall material. This increased incorporation of radioactivity correlates well with increased formation of cell wall material and shows a time-course patt...

Applications of gibberellic acid to the mature form of Hedera helix induce morphological reversions to the juvenile form of growth. The juvenile forms produced are stable with time and differ dramatically from the mature in phenotype. DNA-RNA hybridization techniques have been used to study the RNA populations of juvenile, mature and gibberellic acid-treated mature apices. Hybridization competi...

The elonigationi of rice plants iinduced by the application of cell-free culture filtrates from the li(uid culture of Futsariutm moniliforme was first demonstrated in 1926 by Kurosawa. Twelve years later, Yabuta and Sumiki (1938) were able to isolate in crystalline form two growth-promotinig compounds, gibberellins A and B, from filtrates of this organism; gibberellin A was the maini substaniee...

In order to evaluate the effects of priming materials and duration of priming on the seed physiological enhancement and biochemical traits of germination in pumpkin seeds a factorial experiment was conducted based on a completely randomized design with three replications at the University of Mohaghegh Ardabili. Treatments were priming with water, NaCl (3%), gibberellic acid (20 mg L-1), and asc...

Malaria is a global health issue that will continue to spread with the increase in mosquito populations caused by the rise in global temperatures. The most effective drugs currently available for malaria treatment contain the anti-malarial compound, artemisinin, derived from Artemisia annua. To potentially increase efficiency of artemisinin production in A. annua, I investigated the effects of ...

The effects of a number of growth substances on the absorption and translocation of iron were studied in bean plants. Gibberellic acid application to the trifoliate leaf enhanced absorption of Fe applied to the primary leaf. 2-Chloroethyltrimethylammonium chloride increased absorption by the primary leaf while 6-furfurylaminopurine (kinetin) increased the transport of Fe from the primary leaf t...

a study was conducted to determine the optimum concentration of benzyladenie (ba) and gibberllic acid (ga3) to break the dormancy of gladiolus corms in relation to storage period and to find out the effect of ba and ga3 on growth and development of gladiolus corm and cormels. the effect of ga3 on dormancy breaking was most pronounced in the 100 ppm treatment being 26.93 days while in the water ...
