From: High-throughput phenotyping of seminal root traits in wheat
Illustration of a growth pouch. (A) Wheat seedlings were phenotyped for seminal root angle and number using growth pouches (picture taken 20 days after sowing). (B) For each plant, the left (αL) and the right (αR) angle between each of the first pair of seminal roots and the vertical plane was measured at approximately 3 cm distance from the seed using software (Opengelphoto).
