We investigated several cultural and environmental factors during 1977 which were thought to influence the incidence of moldy walnuts. These studies were meant to be a preliminary survey to determine potential areas of research to pursue. Results of these investigations are not to be considered as control recomnlendations since the studies represent only one year's data and especially during a ...

Ethylene regulates the photosynthetic efficiency of plants grown under challenging environments by regulation antioxidant system and other biomolecules, such as osmolytes (proline). The role ethylene in modulating proline biosynthesis subsequent changes to protect wheat (Triticum aestivum L. cv. WH-711) against heat stress was studied. effects exogenously sourced (as 200 µL L−1 ethephon: 2-chlo...

Hard-surface contact primes the conidia of Colletotrichum gloeosporioides to respond to plant surface waxes and a fruit-ripening hormone, ethylene, to germinate and form the appressoria required for infection of the host. Our efforts to elucidate the molecular events in the early phase of the hard-surface contact found that EGTA (5 mM) and U73122 (16 nM), an inhibitor of phospholipase C, inhibi...

Ceratoides lanata (Pursh) J.T. Howell is a shrub with numerous annual branchlets from the family Chenopodiaceae and is widely distributed in brackish water playas of northern Utah. Seeds had no dormancy, and about 90% of the seeds germinated in nonsaline control. Seed germination decreased with the increase in salinity, and more than 10% of the seeds germinated at 900 mmol/L NaCl. Almost all se...

Berries on field-grown Vitis vinifera cv. Doradillo were treated at different times during stage II with benzothiazole-2-oxyacetic acid or 2-chloroethylphosphonic acid, and measurements were made of their growth and hormone content. The concentration of ethylene was low during stage II and declined as berries ripened. Both 2-chloroethylphosphonic acid and benzothiazole-2-oxyacetic acid caused i...

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...

Chemical ripening of sugarcane is an important component to profitable sugar production in the United States as well as other sugarcane industries throughout the world. Harvesting of sugarcane often begins before the sugarcane reaches the desirable maturity level. This is especially true in the Louisiana sugarcane industry where the window for harvesting is limited because of the risk of freezi...

Understanding leaf and fruit abscission is essential in order to develop strategies for controlling the process in fruit crops. Mechanisms involved in signalling leaf and fruit abscission upon induction by abscission agents were investigated in Citrus sinensis cv. ‘Valencia’. Previous studies have suggested a role for phospholipid signalling; hence, two phospholipase D cDNA sequences, CsPLDa1 a...

Ethephon, an ethylene releaser, is used to stimulate latex production in Hevea brasiliensis. Ethylene induces many functions in latex cells including the production of reactive oxygen species (ROS). The accumulation of ROS is responsible for the coagulation of rubber particles in latex cells, resulting in the partial or complete stoppage of latex flow. This study set out to assess biochemical a...

We evaluated the effect of water and ethephon (2-chloroethyl phosphonic acid) under different doses (500 mg·L−1, 1000 mg·L−1,2000 3000 mg·L−1), with without calcium acetate (CA) in two foliar applications on camphor golden shower saplings. It was aimed for to replace pruning reducing transpiration during transplantation. adopted a completely randomized design as an experimental design. An adequ...
