The diagram above shows a guttation process.

Guttation is a process needed by shrub plants to remove excess water in the form of droplets.

Examples of shrub plants are strawberry plant, wheat, grass and tomato plants.

Guttation only occurs during the night.

During the night, the transpiration process does not occur because stomata are closed.

When there is a high level of moisture content in the soil, the water continuously diffuses into the plant roots which creates a slight rise in root pressure.

The root pressure pushes the water to exude through special leaf tips knows as hydathodes (pore) by forming water droplets.

Rajah di atas menunjukkan proses gutasi.

Gutasi merupakan proses yang diperlukan oleh tumbuhan renek untuk membuang lebihan air dalam bentuk titisan.

Antara contoh tumbuhan renek adalah pokok strawberi, rumput, gandum dan pokok tomato.

Gutasi hanya berlaku pada waktu malam sahaja.

Pada waktu malam, proses transpirasi tidak berlaku kerana stomata tutup.

Apabila tanah mempunyai paras kelembapan yang tinggi, air akan meresap ke dalam akar tumbuhan secara berterusan yang menghasilkan sedikit tekanan akar.

Tekanan akar menolak air untuk mengeluarkan air melalui hujung daun khas yang dikenali sebagai hidatod (liang) dengan membentuk titisan air.
