Mini plant photosynthesis meter to assist consultants The
measurement is based on the chlorophyll fluorescence, a very
weak optical signal emitted by the plant. It is invisible, but
picked up by the instrument and accurately measured. This
readily provides information on the plant's condition and
growth. Weed control is a major application field. To save the
environment, low dose herbicide spraying is more and more used.
But the farmer can’t see if the weed is dying. Here, the miniPPM
provides the answer. The instrument also shows if the crop is
suffering from herbicide treatment. In greenhouse horticulture
the miniPPM is an excellent tool for climate control. The
instrument shows if the crop is stressed due to excess light or
water shortage. It assists in timely light screening and
irrigation, which is essential to prevent growth loss and crop
damage. In the U.S., the instrument is used for plant breeding.
Spruce and pine seedlings are subjected to stress (frost, heat…)
and thereafter measured. Those with th
