Tipburn of lettuce is the drying and dying of leaf tissue along the edges of the leaf. The first symptoms of damage consist of small yellow spots or edges along the leaf edge. Usually they are not found on the oldest leaf, but more on the growing, younger leaves of the head. The damage generally occurs only after a head has formed. The moment when the leaves of the head loosen, is critical for the occurrence of the damage. The very tallest leaves are usually cool. As the deterioration continues, the spots expand and unite, while the tissue disappears. This causes irregularly shaped dead and thinned leaf edges. These often form a starting point for secondary parasitic infections (bacterial rot).

Manoa lettuce is a lettuce variety susceptible to tipburn. Tipburn is the drying and dying of leaf tissue along the edges of the leaf. During a test at a grower in Hawaii it was shown that by increasing the DO levels and adding ultrafine bubbles, reduction of tipburn is realized and quality and production improvements are made.
The turbiti ultrafine bubble generator is a first-class workhorse nanobubble generator. Turbiti has no moving parts so maintenance is minimal, it can be place in the most demanding environments. The nanobubble generator requires a low head pump, so its efficient in energy usage. The Turbiti concept gives you a worry free nanobubble solution generating billions of bubbles for many years.
Selecting a nanobubble generator can be a daunting task when you are new to the technology. In the following article we explain the differences of the various units. This helps you to select the best nanobubble generator for your research, application development or ultrafine bubble production.
acniti is a manufacturer of nanobubble equipment and industrial oxygen concentrators. acniti specializes in the sales and marketing of nanobubble technology.
Nanobubble technology is the next revolution in water and liquids to change their properties by dissolving gases to enhance biological processes, to innovate cleaning and disinfection in a wide range of applications.
