On the other hand, in dicots a primary root (radicle) emerges first and anchors the seedling to the ground and permits it to start absorbing water. A book or scholarly work on this subject. Other crops, such as sweet corn, beans and peas, are most often established by planting seeds directly into the field. It consists of a tough coat or testa enclosing an embryo which is made up of a plumule, a radicle and one or two cotyledons. A few other seeds need light to germinate. But all transplants need to be hardened off before going from the greenhouse out to the field, or they will be damaged by the harsher conditions. A seasonal plant flowers and sets seeds within a particular season, while an annual flowering plant completes its life cycle in one year. Better. B In this, a plant with desired traits is crossed with a plant that does not have the desired traits but has several other traits. When the moisture, light, and temperature conditions are correct, the seedling's development begins with seed germination and the formation of three main parts: A fine-textured seed bed provides good growing conditions, ample seed-to-soil contact, and the ability to plant to a uniform depth. This can especially cause problems when transplanting a tray of seedlings; half are ready to plant in the field, and the other half are too small, with root balls that don't slide easily out of the tray cells.
