Sun-curing tobacco involves simply drying the leaves uncovered in the sun until they are brown and withered. [8] This method is predominantly used in Turkey , Greece , Bulgaria , North Macedonia , Romania and throughout the Mediterranean basin to produce oriental tobacco, [ 9 ] however sun-cured tobacco is also produced in India and Africa as well.
They are arranged in a spiral, forming an erect tuft when young and spreading as they mature, with the oldest leaves dying and forming a hanging skirt around the trunk. The blue-green needle-like leaves are typically 14 to 30 centimetres (5.5 to 11.8 in) long and have a waxy coating. [ 3 ]

Some people have been known to top trees in order to stimulate new growth. When a tree is topped, many adventitious shoots, known as suckers begin to grow from the wound. This is the tree's response to the sudden loss of leaves. Although the tree is able to produce an abundance of suckers, they are susceptible to numerous problems.
Plant senescence is the process of aging in plants. Plants have both stress-induced and age-related developmental aging. [1] Chlorophyll degradation during leaf senescence reveals the carotenoids, such as anthocyanin and xanthophylls, which are the cause of autumn leaf color in deciduous trees.
This reduces the cutting force needed to make a cut still further. Because they crush the stem they are cutting, anvil pruners are best for use on dead wood. [4] Bypass pruners usually work exactly like a pair of scissors, with two blades "passing by" each other to make the cut. At least one of the blades will be curved: a convex upper blade ...
Lophostemon confertus (syn. Tristania conferta) is an evergreen tree native to Australia, though it is cultivated in the United States and elsewhere. Common names include brush box, Queensland box, Brisbane box, pink box, box scrub, and vinegartree. [3]
Many Megachile species use cut leaves to line the cells of their nests. It is thought that the leaf discs help prevent the desiccation of the larva's food supply. [ 1 ] Various species in the genus, especially those in the subgenus Chalicodoma and related groups, do not use cut leaves to line the cells, but instead use fairly dry plant resin ...
