[plant] PHILPS lighting development new growth light formula

PHILPS lighting (Amsterdam stock exchange code: LIGHT), a global leader in the lighting field, recently announced that the company's Grow Wise plant factory research center has produced rich in vitamin C, arugula, its vitamin C content is USDA's value (15 mg /100 g) seven times. Arugula is rich in vitamin C in Holland and Wageningen (Wageningen) University and University of Maastricht (Maastricht) research university cooperation, using PHILPS LED growth formula (without the use of natural light) plants produced under the factory environment.

The test results show that the increase in vegetable functional ingredients by simply changing the planting patterns, such as arugula. Retailers and growers can use PHILPS LED lighting technology based on specific plant formula, to meet the health conscious consumer group of functional food growing demand. The content of vitamin C in vegetables and shelf life are closely related, arugula harvest high levels of vitamin C can also help retailers to extend the shelf life of green vegetables. In addition to vitamin C, and other health related compounds may be affected by the growth formula.

The test results show that we can not only improve crop yield, but also can affect the taste and growth characteristics of crops by changing the growth formula. Provide various parameters needed for crop growth PHILPS formula, including light level, spectrum, light intensity, light uniformity, light position and illumination time, and climate conditions such as temperature, humidity, carbon dioxide concentration and nutrition." PHILPS LED plant lighting global general manager Udo Slooten said van, "this result confirms our research center in PHILPS GrowWise to growers and retailers have brought tangible benefits, they can meet the specific needs of consumer groups, such as improved taste, taste and flavor, make oneself out of the ordinary."

Effect of light on nitrate levels

In the new PHILPS LED lighting growth formula cultivated arugula nitrate level is very low, but the yield is very high. The lower the nitrate content, sugar content is high, the taste is more gentle. LED under the illumination of leaf sugar index can reach 5~8, which can feel the taste of sweet taste. The nitrate content obtained in this test, the value is much lower than the EU regulations, ranging from 7000 to 6000 mg/kg. This low nitrate arugula in favor of Poland, Russia and Finland retailers, consumers in these countries to meet the growing demand for low nitrate in food. Using another growth formula, and high content of nitrate can also produce high vitamin C arugula, meet consumer demand in this area, and other nutrient content is not affected.

This experiment in Eindhoven (Eindhoven) PHILPS GrowWise center to carry out, the centre is the same type of the largest plant factory research facility, respectively, in cooperation with Wageningen University in Holland to carry out research in plant science and the shelf life of Holland and University of Maastricht cooperation on health food innovation. Arugula in four kinds of light in the test conditions are three different combination of LED lighting and an artificial light for the sun and high-pressure sodium lamp. We also study the effect of high proportion of red light blue and lofty light shelf life and nutrient content of vegetables in the harvest period.
