Abstract. The experiments were carried out with maize (Zea mays L.) seedlings, hybrid Kneja 530, grown hydroponically in a growth chamber. Twelve-day-old plants were foliar treated with putrescine, N1-(2-chloro-4-pyridyl)-N2-phenylurea (4-PU-30), and abscisic acid (ABA) at concentrations of 10−5m. Twenty-four hours later the plants were subjected to a water deficit program, induced by 15% polyethylene glycol (PEG; molecular weight, 6,000). Three days after drought stress half of the plants were… 
The effect of abscisic acid and benzylaminopurine on photosynthesis and transpiration rates of maize ( Zea mays L.) under water stress and subsequent rehydration
The young plants of maize were cultivated as sand culture under controlled conditions in a greenhouse. The water stress caused by interruption of irrigation for a period of 8 days had the effect of
IMPROVING THE THERMO TOLERANCE OF WHEAT PLANT BY FOLIAR APPLICATION OF ARGININE OR PUTRESCINE
The exposure of wheat plants cv. Giza 168 to high temperature stress (35C±2) for 4 or 8 hours significantly decreased the growth parameters, the yield components, putrescine (Put), total endogenous
Growth promotion of bean (Phaseolus vulgaris L.) by a polyamine-producing isolate of Streptomyces griseoluteus
TLDR
This study is the first to demonstrate the potential of a polyamine-producing actinomycete to promote plant growth and the first published report of the production of polyamines by streptomycetes.
Coronatine Alleviates Polyethylene Glycol-induced Water Stress in Two Rice (Oryza sativa L.) Cultivars
We studied the effects of coronatine (COR), a structural and functional analogue of jasmonates, on the drought tolerance of two rice cultivars, Handao 297 (a drought-tolerant upland rice) and Yuefu
Antioxidant Defense System in Heat Shocked Wheat Plants Previously Treated with Arginine or Putrescine.
TLDR
Arginine or putrescine treated plants prior to high temperature exposure showed significant reductions in the activities of POX, PPO and IAA - oxidase enzymes and significant increases in SOD and CAT activities than those of the corresponding plants exposed to highTemperature stress alone.
Effects of Coronatine on Growth, Gas Exchange Traits, Chlorophyll Content, Antioxidant Enzymes and Lipid Peroxidation in Maize (Zea mays L.) Seedlings under Simulated Drought Stress
TLDR
The application of coronatine alleviated the drought stress in maize seedlings and enhanced their tolerance of water stress through changes in physiological and anti-oxidant enzyme activities.
Effect of Benzylaminopurine on Rehydration of Bean Plants after Water Stress
TLDR
Both types of application of 1 μM BAP slightly improved recovery of plants during rehydration after water stress in terms of increased gad, gab and PN, i.e., parameters which were markedly decreased by mild water stress.
Response of sweet basil to jasmonic acid application in relation to different water supplies.
Pot experiments were carried out at the Faculty of Agriculture, Minoufiya University in 2008 and 2009 seasons, to investigate the effect of water stress levels 100 (w0), 60 (w1) and 40 (w2) % of
Exogenous putrescine attenuates the negative impact of drought stress by modulating physio-biochemical traits and gene expression in sugar beet (Beta vulgaris L.)
TLDR
This study provided compelling evidence of increased drought stress tolerance in two sugar beet genotypes when treated with exogenous putrescine (Put) at the seedling stage, and results strongly suggested that Put conferred drought tolerance mostly by enhancing antioxidant enzymes activities that regulated homeostasis of reactive oxygen species.

The Effect of Water Stress upon Polyamine Levels in Barley (Hordeum vulgare L.) Leaves
TLDR
The effect of water stress on leaf polyamine content of four Hordeum vulgare varieties, Alger/Ceres, Palmella Blue, Rihane and Roho, with different drought characters was studied and one common response was identified; the accumulation and subsequent loss of putrescine was dependent upon the maintenance and loss of leaf turgor respectively.
Water Relations and Growth of the flacca Tomato Mutant in Relation to Abscisic Acid.
TLDR
It is concluded that, in some cases, ABA may promote leaf growth via its effect on leaf water balance through the involvement of ABA in responses to water stress.
Membrane lipid changes in root cells of rape (Brassica napus) as a function of water‐deficit stress
TLDR
Rape seedlings (Brassica napus L. cv. Brink) were exposed to repeated water-deficit stress and the total amount of acyl lipids as well as phospholipids decreased drastically, however, the relative distribution of individual phospholIPids was constant and independent of stress.

Abscisic Acid and cytokinin contents of leaves in relation to salinity and relative humidity.
TLDR
It is tentatively suggested that variations in the water content of leaves constitute a primary signal for modification of plant hormonal balance.

TLDR
It is suggested that this differing response of polyamine metabolism to osmotic stress may account in part for the failure of cereal mesophyll protoplasts to develop readily in vitro.
