Tulip Drumline

Technical Profile and Biological Traits of 'Drumline' Tulips

The 'Drumline' tulip is classified as a double late variety, which dictates its specific cultivation requirements. Unlike early-blooming groups, this variety necessitates precise soil moisture control during the intensive stalk growth phase, as its late flowering period often coincides with periods of thermal stress.

Phytosanitary Resistance and Defense

The core strength of this hybrid lies in its genetic resistance to significant soil-borne pathogens:

• Verticillium Wilt: The variety shows high resistance to fungal occlusion of the vascular system, effectively mitigating the risk of sudden wilting during the budding stage.
• Phoma: The dense epidermal structure and robust physiological activity of the tissues allow the plant to successfully withstand stem infections, which is essential for maintaining high-quality cut flowers.

Flower Architecture and Growth Parameters

'Drumline' produces a dense, multi-petaled bloom with a vibrant red hue. Its medium height provides an optimal equilibrium between stem integrity and the aesthetic value of the cut product. The double-flower structure requires protection from mechanical damage caused by precipitation, as the heavy head can accumulate moisture, creating a risk of lodging if planting density is not strictly managed.

When cultivated in open field conditions or greenhouses, it is important to note that the medium height makes this variety highly compatible with standard operational procedures. However, careful attention to bulb planting depth is required; for late-blooming cultivars, this metric is critical for establishing a robust root system capable of supporting the development of a substantial double bloom.
