The feedback regulation of ethylene biosynthesis in banana [Musa sp. (AAA group, Cavendish subgroup) cv. Grand Nain] fruit was investigated in an attempt to clarify the opposite effect of 1-methylcyclopropene (1-MCP), an ethylene action inhibitor, before and after the onset of ripening. 1-MCP pre-treatment completely prevented the ripening-induced effect of propylene in pre-climacteric banana f...

We investigated the interaction between indole-3-acetic acid (IAA) and ethylene in the regulation of the seasonal periodicity of tracheid production in 1-year-old balsam fir (Abies balsamea (L.) Mill.) cuttings collected at different times during the dormant period. The cuttings were left with their buds intact or were debudded and treated either apically with IAA or 2-chloroethylphosphonic aci...

to survey the effects of flooding during the reproductive growth stages of aerenchyma formation and ethylene production in soybean cultivar dpx experiment  the completely randomized factorial was in 2012 in gorgan university of agricultural sciences and natural resources. factors examined include nutrition levels in three levels (1 - inoculated with bacteria japonicumbradyrhizobium 2 - non-inoc...

Two peaks of ethylene production occur during the development of cotton fruits (Gossypium hirsutum L.). These periods precede the occurrence of young fruit shedding and mature fruit dehiscence, both of which are abscission phenomena and the latter is generally assumed to be part of the total ripening process. Detailed study of the dehiscence process revealed that ethylene production of individu...

After alfalfa (Medicago sativa) seedlings were exposed to approximately 0.7 microliter per liter SO(2) for 8 hours, elevated ethylene and ethane production was observed. Ethylene production peaked about 6 hours and returned to control levels by about 24 hours following the fumigation, while ethane production peaked about 36 hours and was still above control levels 48 hours after the fumigation....

BACKGROUND AND AIMS Leaf longevity is an important plant functional trait that often varies with soil nitrogen supply. Ethylene is a classical plant hormone involved in the control of senescence and abscission, but its role in nitrogen-dependent leaf longevity is largely unknown. METHODS Pot and field experiments were performed to examine the effects of nitrogen addition on leaf longevity and...

Shoot inversion in Pharbitis nil results in the enhancement of ethylene production and in the inhibition of elongation in the growth zone of the inverted shoot. The initial increase in ethylene production previously was detected within 2 to 2.75 hours after inversion. In the present study, the initial inhibition of shoot elongation was detected within 1.5 to 4 hours with a weighted mean of 2....

Citrus fruits infected with the fungus Penicillium digitatum substantially increase the production of the plant hormone ethylene. In this study, the regulation of ethylene biosynthesis in Citrus sinensis-infected fruits and its putative involvement in an active defence response against P. digitatum infection is examined. Ethylene production is demonstrated as being the result of the co-ordinate...

Two cultivars of Exacum af®ne, White Princess and Royal Dane, were grown under supplementary light conditions (70 and 100 mmol mÿ2 sÿ1). The higher light intensity reduced the production time and resulted in increased ̄ower development during the post-production period in an interior environment. To test ethylene responses, the plants were sprayed with the anionic silver thiosulphate complex (S...
