Germination

A loss in germination of just a few percent translates into a similar reduction in profit. Each species has a specific temperature at which the seeds germinate the quickest; these temperatures can easily be found on the Internet.

The ideal environment for germination is a temperature-controlled germination room. If you wish to grow a number of different species at the same time, look at the germination tables and choose a compromise temperature; this may not be ideal for each species, but will enable all the plants to germinate well. It’s usually in the mid-20°C range.

Preparation Stack the planted seed trays, which should be filled with growing medium and moist, in the germination room.

If the growing medium is at the correct temperature at stacking, the trays can be placed on top of one another without spacing. If not, put thin strips of wood or something similar between the trays to enable air to circulate between them to stabilise the temperature.

If there is no gap, the growing medium may decompose and heat up, like a mini compost heap, thereby compromising germination. Always check the temperature between the trays.

Plant phenotyping plays a crucial role in understanding variations in the phenotype of individual plants affected by environment, management, and genotype. Measurement of seed germination is an important phenotyping stage as germination impacts on the whole plant growth process. However, germination measurement has been limited to germination percentage of a seed population. Understanding of the germination time, from sowing to outbreak of the radicle from seed coat, at a single seed level is essential. How individual germination time and further plant growth are affected by its microenvironment and management factors remains elusive. Plant phenotype measurement system was developed to assess individual germination time of romaine lettuce (Lactuca sativa L. var. longifolia), using time-series two-dimensional camera images, and to analyze how microenvironment (volumetric water percent in seed tray, individual seed surface temperature and air temperature) and management factors (coated/uncoated seeds) affect the germination time for plant cohort research, emphasizing practicality in commercial cultivation. Germination experiments were conducted to demonstrate the performance of the system and its applicability for a whole plant growth process in a plant factory for commercial production and/or breeding. The developed phenotyping platform revealed the effects of microenvironment and management factors on germination time of individual seeds.

Germination and growing requirements for flowers, vegetables and herbs from seed can vary depending on the type of plant grown. With moisture, light, fertilizer and other considerations, there are many factors that influence germination and subsequent quality of seedling growth. However, there are also…

Seed germination is a critical developmental phase for seedling establishment and crop production. Increasing salinity stress associated with climatic change can pose a challenge for seed germination and stand establishment of many crops including lettuce. In a recent study, researchers show that water…
