Growth regulator gives earlier harvest in artichokes

New Curriculum Gives DMD Students Earlier Clinical Experience.

Melatonin; Growth regulator and strong antioxidant in plants

Melatonin (N-acetyl-5-methoxytryptamine) is an indole metabolite derived from tryptophan and synthesized in plant cells in the chloroplasts and mitochondria. Melatonin is present in all plant species, with large variations in its level depending on the plant organ or tissue, it is a molecule endowed with a multitude of functions that make it worthy to be referred to as a plant growth regulator....

Earlier snowmelt and warming lead to earlier but not necessarily more plant growth

Climate change over the past ∼50 years has resulted in earlier occurrence of plant life-cycle events for many species. Across temperate, boreal and polar latitudes, earlier seasonal warming is considered the key mechanism leading to earlier leaf expansion and growth. Yet, in seasonally snow-covered ecosystems, the timing of spring plant growth may also be cued by snowmelt, which may occur earli...

Harvest and Post-harvest Operations

Harvest and post-harvest operations constitute principal constraints to rice production, especially in irrigated systems, because of the larger yield that has to be handled. Post-harvest crop losses of up to 35% have been reported and attributed to inefficiency of manual threshing of rice by small-scale farmers. This leads to poor grain quality and rejection of locally produced rice. The Africa...
