Budding is most commonly done when there is good sap flow in the plants.
Budding is inserting a single bud from a desirable plant into an opening in the bark of a compatible rootstock to create an advantageous variety (cultivar) and rootstock combination.
Vegetative buds are used as a scion. The time of budding depends upon the availability of buds and cell sap flow in the rootstock seedlings so that bark separates easily to take scion bud.

The Queen of tropical fruits is Mangosteen.
The fruit is dark purple with a soft white fragrant edible centre very similar in construction to the sections of an orange. The taste is amazing with an exceptional blend of sweetness and tanginess and melts in your mouth.

Pungency in onion is due to the presence of Allyl propyl disulphide.
Onion is valued for its bulbs having characteristic odour, flavour and pungency, which is due to the presence of a volatile oil allyl propyl disulphide.

Quantitative traits having low heritability are improved by using recurrent selection.
Recurrent selection means repeated cycles of selection and breeding aimed at gradual genetic improvement of a few key traits in a single species.
Genomic selection and marker-assisted recurrent selection have been applied to improve quantitative traits in many cross-pollinated crops.
The benefits of breeding are cumulative in that each cycle or generation of improvement builds upon advances made in prior generations.

Jelmeter is used to determine pectin content.
A jelmeter is a graduated glass tube with an opening at each end. It is used to determine the amount of pectin in fruit juice. It is an index of the amount of sugar to be used.
