📄 Influence of Environmental Factors Light, CO2, Temperature, and Relative Humidity on Stomatal Opening and Development: A Review

Stomata, the microscopic pores surrounded by a pair of guard cells on the surfaces of leaves and stems, play an essential role in regulating the gas exchange between a plant and the surrounding atmosphere. Stomatal development and opening are significantly influenced by environmental conditions, both in the short and long term. The rapid rate of current climate change has been affecting stomatal responses, as a new balance between photosynthesis and water-use efficiency has to be found. Understanding the mechanisms involved in stomatal regulation and adjustment provides us with new insights into the ability of stomata to process information and evolve over time. In this review, we summarize the recent advances in research on the underlying mechanisms of the interaction between environmental factors and stomatal development and opening. Specific emphasis is placed on the environmental factors including light, CO2 concentration, ambient temperature, and relative humidity, as these factors play a significant role in understanding the impact of global climate change on plant development.

For years, James Dick, a horticulturalist from Vermont in the Western Cape, researched better ways of growing food on a micro scale.

“I came away from university with the idea, but it took a lot of brainstorming and prototypes before I got the concept,” he recalls.

In 2010, the idea of the HiGro Tower Garden System finally crystallised in his mind.

“It’s a system designed for high-density living environments in poorer communities, especially for the busy person with limited time for shopping. The idea is to have a full, healthy meal at your back door, free of high maintenance costs,” he explains.

How it works  The HiGro system is a vertically segmented column for growing flowers, leafy greens, peas, beans, herbs and strawberries, amongst other plants.

“Four to eight modules interlock to form the column. Each module is filled with 4,5ℓ of sphagnum peat moss and green fibre pre-enriched with a little fertiliser to get the plants started,” Dick explains. This growing medium has high water-retention and can last for as long as two years.

The system is designed to grow plenty of food with very little water and does not rely on electricity. Instead, it is irrigated by a hand-pumped 5ℓ compression sprayer that drives a water and fertiliser solution through the drippers and into the modules.
