Today in our “Petiole App in Action” we will speak about black currants. We found that many of the researchers, who work with our mobile application, focus on these berries. That is why, we decide to make our own measurement of leaf area and chlorophyll content in black currants leaves.
The blackcurrant, also known as black currant or cassis, is a deciduous shrub in the family Grossulariaceae grown for its edible berries. It is native to temperate parts of central and northern Europe and northern Asia. In fact, there it prefers damp fertile soils. Also, it is widely cultivated both commercially and domestically.
Using Petiole mobile app we measured a leaf of blackcurrants. To list, for this task we followed the next steps:
As a result, we got the following measurements of these blackcurrants leaf:
Estimated time of measurement: less than one second Leaf area: 33,8 cm2 Dark green index: 0,69 You can download Petiole app for your Android phone here.
By the way, it is time to enjoy black currant leaves. One teaspoon of milled dried black currant leaves contains as much vitamin C as a lemon. Can you imagine this? However, it is important to gather these leaves after the blooming (actually, now). After some time, the chemical makeup of leaves changes and all useful chemicals go in berries. The larger leaf surface area in black currant and a higher level of chlorophyll in a leaf – more vitamin C.
