Summary
Fruit transpiration in kiwifruit is driven by relative humidity and temperature, not radiation or windspeed. A new model accurately predicts fruit transpiration rates throughout development using weather data.
Area of Science:
- Horticultural Science
- Plant Physiology
- Agricultural Meteorology
Background:
- Fruit storage quality variability causes significant commercial losses.
- Understanding fruit transpiration is key to improving fruit storage quality.
- A causal chain links weather, fruit transpiration, calcium, and storage quality.
Purpose of the Study:
- Investigate environmental drivers of Hayward kiwifruit transpiration.
- Develop a predictive model for fruit transpiration.
- Identify key factors influencing fruit water loss.
Main Methods:
- Measured hourly fruit transpiration via weight loss over the season.
- Collected concurrent meteorological data (radiation, temperature, humidity, windspeed).
- Developed a predictive model using Fick's Law of transpiration.
Main Results:
- Fruit transpiration varied diurnally and decreased seasonally.
- Skin conductance was the dominant fruit variable affecting transpiration.
- Relative humidity and temperature were the primary environmental drivers; radiation and windspeed were not significant.
Conclusions:
- The developed model accurately predicts kiwifruit transpiration rates.
- Predictions are valid across different times of day and fruit developmental stages.
- The model enables continuous estimation of fruit transpiration using standard weather data.

02:04Regulation of Transpiration by Stomata
During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.
01:57Adaptations that Reduce Water Loss
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
02:03Xylem and Transpiration-driven Transport of Resources
The xylem of vascular plants distributes water and dissolved minerals that are taken up by the roots to the rest of the plant. The cells that transport xylem sap are dead upon maturity, and the movement of xylem sap is a passive process.
02:16Light Acquisition
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.
02:45Responses to Heat and Cold Stress
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Overview
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
