Chickpeas & Beans
Desi and Kabuli chickpeas are the two market classes produced in Saskatchewan. Desi types have smaller, angular seeds with yellow to brown seed coats. Kabuli types have a rounded seed with a cream-coloured coat.
Chickpea germinates with the cotyledon and seed coat remaining below ground (hypogeal germination). The first two nodes on the stem contain the scale leaves. These scale leaves remain below the ground during early plant emergence, offering the plant some late spring frost tolerance and opportunity for regrowth if the top growth is damaged in the seedling stage. The first scale leaf may be below the ground, but the first true leaf is produced at the third node position. Chickpea scale nodes are typically short. On average, a new node is produced every three to four days.
Beans differ from lentils, peas, and chickpeas in that the bean seeds do not stay below the ground during germination. Instead, the cotyledons push upward through the soil and become exposed above the surface. This type of germination makes the seedling very vulnerable to damage. The first true leaves are single opposite leaves. All later leaves have three leaflets, called a trifoliate, arranged on alternate sides of the stem.
