example 1

[0122] As an example, the present invention can be implemented as follows. Roses are grown in a greenhouse under normal conditions of temperature, moisture, nutrients and sunlight. In addition, for example, the amount of ozone in the greenhouse atmosphere is controlled by using an ozone purifier to reduce the amount of ozone in the greenhouse atmosphere. In addition, the greenhouse is well sealed to avoid ozone intrusion from the outside atmosphere.

[0123] The ozone concentration level in the greenhouse is kept as low as possible, preferably below 20-30 ppbv, at least throughout the period of early ontogeny as defined above. Thereafter, after early ontogeny, the plants can be grown in more permissive conditions, or they can be moved outside the greenhouse to continue growing.

[0124] Exposure of plants to favorable growth conditions will result in plants having a lower respiration rate at maturity relative to plants exposed to high ozone ambient conditions, and such plant...

example 2

[0126] The examples described below demonstrate that plant ontogeny stages as described herein provide memory effects on respiration through the AOX pathway. In particular, it will be shown that this ontogenetic stage is a learning period during which oxidative stress e.g. induced by ozone irreversibly enhances non-ATP-induced AOX pathways in total dark respiration under environmental conditions of high ozone concentrations or AOX ingredients. Respiration utilizing this AOX pathway is "alternative oxidase pathway respiration," also known as "alternate pathway respiration (APR)," "cyanide-insensitive respiration," or "SHAM-sensitive respiration."

[0127] Measurements under three environments with different ozone concentration conditions showed that cotton plants have a well-defined and fixed maximum respiratory efficiency when they enter the reproductive phase (i.e., during ontogeny) after the end of their vegetative growth phase, expressed as [ TDR-AOX] / [TDR], where TDR refe...

Abstract

The invention relates to a method for increasing the yield of a plant grown under conditions that cause periodic oxidative stress in said plant, comprising the step of growing a seedling, tissue culture or plantlet into a plant, and further comprising the step of manipulating said plant or the environment of said plant such that an increase in the rate of respiration and/or protein turnover in said plant due to said periodic oxidative stress is intentionally prevented during the early ontogeny of said plant.

Description

field of invention [0001] The present invention relates to the field of crop production. More specifically, the present invention relates to methods of growing plants and methods of increasing the average annual yield of crops in crop growing areas. The invention also relates to plants with increased yield produced by the method according to the invention, and to a greenhouse comprising means for controlling the content of reactive oxygen species in the atmosphere. Background of the invention [0002] Global demand for wheat, rice, corn, and other major grains is projected to rise steadily over the next 20 years. In addition to being a food source, this demand will rise due to the growth of biological methods to produce plant fuels and chemicals. Increasing production to meet this demand through increased land use is unlikely; although better crop management would help somewhat, most agricultural experts agree that this expected shortfall must be made up by increasing crop...
