Vine Water Status
Vine water status refers to the water relations of a plant, including its ability to take up water from the soil, transport it through the plant, and use it for various physiological processes. The water status of a grapevine can be described in terms of its water...
Vine Balance
Vine balance refers to the equilibrium between the grapevine's vegetative growth (leaves, shoots, and roots) and its reproductive growth (fruit production). When a grapevine is in balance, its vegetative growth and fruit production are in harmony, which allows the...
The Vineyard Calendar
Planning Key Vineyard Activities Grape growers need to understand the annual vine cycle to determine dates for key vineyard activities such as pruning, fertilisation, cyanamide application, harvesting, and so forth. These activities have a significant impact on grape...
The Growing Cycle of Grapevines
Plant development is characterised by two stages of growth: Vegetative growth is where the plant accumulates resources needed for flowering and fruit development by favouring the growth of the root system and leaves. Reproductive growth where flowering and fruit set...
