This research aims to study the proteins transformation in zea maize plant
seedlings cells, (GHOTA 82) under the influence of phyto hormone Auxin &
grothregulators 2,4-D and IBA.
Maize plant seeds were germinated in water medium for six days in
d
arkness and temperature of 25 ºC.
The quantity different groups of proteins, were analyzed in the stem cells of
the developing seedling mesochotyles after incupation in darkness water and in
different solutions of auxin, 2, 4D & IBA (in concentration 50 mg/l) for 20
hours in 26 ºC.
The results showed that had inhibition effects on hydrolysis of protein
groups in zea maize plant seedlings cells.
Investigate studied the activity of some enzymes in zea maize plant seedlings
cells, (Ghota 82) under the influence of phytohormone Auxin & growth
regulators 2,4-D and IBA.
Maize plant seeds were germinated in water medium for six days in
darknes
s and temperature of 260C.
Then stem cells of the developing seedling were incupated in darkness with
water or in different solutions of auxin, 2,4-D & IBA (50 mg/l) for 20 houre in
30 0C. Then magared the activity of α-Amylase, RNAase, Catalayse, Guaiacol
Peroxidase, Ascorbate oxidase in the stem cells
The results showed that the incupation has defferent effects.on hydrolysis
and oxidative enzymes in zea maize plant seedlings cells.
Single nodes and axillary buds excised from adult trees of Myrtle (Myrtus
communis L.) grown in the field under natural conditions at Damascus
countryside (Ain Elfiegh) were used as primary explants, which were surfacedisinfected
by 70% Ethanol an
d Clorox containing 5.25 % Sodium Hypoclorite
with a drop of Tween 20 for different periods and concentrations before being
placed onto MS basal medium. Established cultures were then transferred onto
MS basal medium containing a combination of growth regulators at different
concentrations (BA at 2.22 and 4.44 μM) each with NAA at 0.54, 1.62, 5.4 μM
or 1.47 μM IBA with GA3 at 0.58 μM for all tratments. Multiplication rate of
12.8-fold was achieved every 4 weeks on MS medium supplemented with 4.44
μM BA with 1.47 μM IBA and GA3 at 0.58 μM.
A successful and detailed in vitro propagation system for rapid
micropropagation of three apple rootstocks: MM ١٠٦, EM ٧ and M ٢٦ has
been developed. Shoot tips and axillary buds excised from field-grown trees
were used as explants, which were surface-disinfected with mercury bichloride,
or with solution of sodium or calcium hypochlorite followed by three rinses
with sterile distilled water.
A study on the propagation of female kiwi trees (Hayward variety) by wooden
cuttings, using plant growth regulators, was conducted at Latakia Agricultural
Research Centre during the seasons 2009, 2011 and 2012. Two dates for collecting
cuttings (J
anuary and February) from kiwi trees which were selected. On each date,
the cuttings were divided into three groups according to cutting location on the
shoot (basal, middle and apical). The NAA and IBA growth regulators were applied
at several concentrations, in addition to two treatments of the mixture of both growth
regulators.
