Faculty operates in two locations as main administration buildings are situated in the main campus of University of Peradeniya and a separate sub-campus is located in Mahailuppallama, North Central province of Sri Lanka. It was established in 1947 with an initial batch of 16. Mahailuppallama sub-campus was established in 1968.
The Hardy Advanced Technological Institute [5] is located in Ampara, Sri Lanka. [6] Founded in 1956 by Prof. Allen Hardy as the Technical Training Institute with aid from the Colombo Plan, Food and Agriculture Organization (FAO) and the Asia Foundation, it was renamed as Hardy Senior Technical Institute (HSTI) in 1967.

When fertilization does not occur, seedless grapes are formed, which are sought after for the production of raisins. Regardless of pollination and fertilization, most plants will produce around 100 to 200 grapes. [14] The skin of the grape accounts for 5 to 20% of the total weight of a grape depending on the variety. [15]
Following fruit set, the grape berries are green and hard to the touch. They have very little sugar and are high in organic acids. They begin to grow to about half their final size when they enter the stage of veraison. This stage signals the beginning of the ripening process and normally takes place around 40–50 days after fruit set.
During the summer growing season, pruning can involve removing young plant shoots or excess bunches of grapes with green harvesting. Vine training systems utilize the practice of trellising and pruning in order to dictate and control a grape vine's canopy which will influence the potential yield of that year's crop as well as the quality of the ...
In viticulture, the grape cluster (also bunch of grapes) is a fertilized inflorescence of the grapevine, the primary part of this plant used for food [1] (grape leaves are also used in some culinary traditions). [2] The size of the grape bunch greatly varies, from few grams to kilograms, depending on the grape variety and conditions during the ...
Grape berries follow a double sigmoid growth curve. The initial phase of berry growth is a result of cell division and cell expansion. As berry growth of phase I slows this is termed the lag phase. The lag phase is not a physiological growth stage, but an artificial designation between the two growth periods of grape berry development.
Phomopsis cane and leaf spot is a disease that causes symptoms in the common grapevine species, Vitis vinifera, in many regions of the world. [2] This disease is mainly caused by the fungal pathogen, Phomopsis viticola, and is known to affect many cultivars of table grapes, such as Thompson Seedless, Red Globe, and Flame Seedless. [3]
