In biology, the BBCH-scale for cucurbits describes the phenological development of cucurbits, such as cucumber, melon, pumpkin, marrow, squash, calabash and watermelon, using the BBCH-scale. The phenological growth stages and BBCH-identification keys of cucurbits are:
Similar growth stages of each plant species are given the same BBCH code. Each code has a description and important growth stages have additional drawings included. The first digit of the scale refers to the principal growth stage. The second digit refers to the secondary growth stage which corresponds to an ordinal number or percentage value.
The watermelon is an annual that has a prostrate or climbing habit. Stems are up to 3 metres (10 feet) long and new growth has yellow or brown hairs. Leaves are 60 to 200 millimetres (2 + 1 ⁄ 4 to 7 + 3 ⁄ 4 inches) long and 40 to 150 mm (1 + 1 ⁄ 2 to 6 in) wide. These usually have three lobes that are lobed or doubly lobed.

Agronomic studies often focus on the above-ground part of plant biomass, and consider crop growth rates rather than individual plant growth rates. Nonetheless there is a strong corollary between the two approaches. More specifically, the ULR as discussed above shows up in crop growth analysis as well, as: = . = .
The plants in this family are grown around the tropics and in temperate areas of the world, where those with edible fruits were among the earliest cultivated plants in both the Old and New Worlds. The family Cucurbitaceae ranks among the highest of plant families for number and percentage of species used as human food. [5]
On top of the gradual growth of the plant, the image reveals the true meaning of phototropism and cell elongation, meaning the light energy from the sun is causing the growing plant to bend towards the light aka elongate. Plant growth and development are mediated by specific plant hormones and plant growth regulators (PGRs) (Ross et al. 1983). [10]
