This application relates to methods and materials for providing a benefit to a seed or seedling of an agricultural plant (e.g., an agricultural grass plant), or the agricultural plant derived from the seed or seedling. For example, this application provides purified bacterial populations that include novel seed-origin bacterial endophytes, and synthetic combinations of seeds and/or seedlings (e.g., cereal seeds and/or seedlings) with heterologous seed-derived bacterial endophytes.

A seed transportation system and method for using the same, the seed transportation system including a rotatable wheel with at least one seed supports for holding a seed, wherein the at least one seed support has one or more fixed support structures configured to restrict movement of the seed in a circumferential direction relative to the rotatable wheel and in a direction away from an axis of rotation of the rotatable wheel, and wherein the at least one seed support has an access opening in its radially outer side, the access opening permitting access to the seed for creating an opening in the seed.

A method of treating a seed for sowing is provided for improving subsequent plant performance comprising the step of treating the seed for sowing with UV-B irradiation.

A seed potato cutting system includes a cutting roller unit with an endless roller chain, having a plurality of parallel roller sets, each roller set including a plurality of cylindrical rollers on a common axle, with lateral gaps between adjacent rollers, configured to convey seed potatoes toward a distal end of the roller chain. A plurality of pairs of parallel upright blades are disposed at the distal end, the blades having common rotational axes and a cutting edge that passes within a lateral gap between rollers, each pair of blades having a common adjustable blade gap therebetween.

A seed flow chamber for handling seed and grain commodity, especially for use with a seed treatment applicator. Seed flow is received through an upper inlet opening configured to receive a flow of seed and discharged through a lower discharge opening. A diverging guide member splits the seed flow. A converging guide member disposed below the diverging guide member reunites the seed flow prior to discharge. The converging member has a downward sloping surface and an air vent, such as a plurality of airflow apertures connected to a plenum. The air vent is configured to communicate with an air supply. A vacuum ventdisposed below the diverging guide memberis configured to communicate with a vacuum source. A fan system recirculates air between the air vent and the vacuum vent. Dehumidifier may condition the air supply to assist with drying.

A rotary atomizer is disclosed for the even distribution of a treatment fluid within a treatment chamber. The treatment fluid is delivered onto a rotating disk atomizer through multiple outlet ports. Fluid passages provide each outlet port with an even flow of treatment fluid at generally the same time and rate. This even and simultaneous flow of treatment fluid results in a more even distribution of treatment fluid on the seed that flows through the treatment chamber throughout the treatment cycle.
