Chrysanthemum transportability

Chrysanthemum transportability is assessed not by a quantitative parameter, but through compliance with quality standards, such as stem integrity, absence of deformations, leaf yellowing, and signs of wilting. To determine suitability for long-distance transport, breeding companies use specific stress tests, including evaluating the susceptibility of leaves to yellowing during simulated transport and testing the resistance of inflorescences to grey mold under high humidity conditions.

Key biological factors of transportability include genetic resistance to temperature fluctuations, ethylene exposure, and loss of turgor. An important varietal trait is the susceptibility to stem curvature due to geotropism or phototropism, as well as resistance to bacterial vascular occlusion. Highly transportable varieties, when kept within a temperature range of +2 to +5°C, are capable of maintaining their commercial appearance and vase life for up to 14–20 days.
