Cambium activity is influenced by the climatic changes The cambium is more active during the spring that forms plenty of xylem vessels with wider cavities also called as earlywood or the spring wood. Springwood constitutes a major part of the annual ring and occurs at the beginning of an annual ring. It contains larger and wider elements and wood is lighter in color.

Cambium activity is influenced by the climatic changes The cambium is more active during the spring that forms plenty of xylem vessels with wider cavities also called as early wood. In winter this activity slows down and gives rise to narrower xylem elements. This is the late wood or autumn wood. 

Some of the dividing pericycle cells are committed to the asymmetric, formative divisions that give rise to lateral root primordia and lateral root formation. The endodermis is the central, innermost layer of cortex in some land plants. It is made of compact living cells surrounded by an outer ring of endodermal cells with hydrophobic substances (Casparian Strip) to restrict the apoplastic flow of water to the inside. Sapwood is the soft outer layers of recently formed wood between the heartwood and the bark, containing the functioning vascular tissue and not central, dark colored, non-conducting part of secondary xylem.

• In the spring season, cambium is very active and produces a large number of xylary elements having vessels with wider cavities and form spring or earlywood and has light colour with lower density while late or autumn wood is formed in winter and vessels are less in number with a narrow lumen which is dark in color with high density.

Brassica juncea, commonly known as Indian Rye or Indian mustard is a species of a mustard plant. Brassica species flowers are complete, bisexual, i.e., with functional male (androecium) and female (gynoecium), including stamens, carpels and ovary. Pollination is entomophilous i.e., by insects, or cleistogamy i.e., by self or allogamy i.e., by cross-pollination. 

Wheat is the most widely grown crop in the world and provides 20% of the daily protein and of the food calories for 4.5 billion people. It is the second most important food crop in the developing world after rice. The most planted crops throughout the world are wheat and maize (corn).
