Secretes sugar droplets eh? What kind of sugar I wonder? Glucose? Sucrose? Just interested. Well done on the ID Ivygirl_5

Thanks for the compliment kotoreru. Plant taxonomy is my favorite hobby.

If I remember my Plant Physiology correctly the process of producing sugar droplets is called Guttation.

When stomata are closed at night and transpiration cannot occur root presure causes the plant to secrete fluid which is composed primarily of sugars, but also contains other organic compounds and minerals. The sugar is mainly glucose, but depending on the plant other sugars may be present in differing amounts. i.e. Glucose has the highest concentration in rye and barley fluids and galactose highest in wheat. Guttation is common in grasses.

Fascinating, many thanks

Look up my other post. Guttation excrets xylem solution, which contains a neglijable amount of sugar.
Xylem solution is composed mainly of water(99%, give or take). The other one percent is made out mainly of mineral ions(Ca, K, Cl, Mg and many more). Organic substances are rare, which the most common organic substances present in the xylem being the hormones cytokinines.

Thanks for catching my mistake.
