Question

A major loss occurs when stage III plants are removed from media and moved to soil in pots where they die before selling to the public. How is “acclimitazation” and “hardening off” achieved/what steps can be taken to toughen up plants and roots before (at stage III) and after (stage IV) being placed in soil?

Answer 1

ANS)

Numerous plants, for example, maple trees, irises, and tomatoes, can survive solidifying temperatures if the temperature steadily drops lower and lower every night finished a time of days or weeks. A similar drop may execute them on the off chance that it happened abruptly. Studies have demonstrated that tomato plants that were adjusted to higher temperature more than a few days were more productive at photosynthesis at moderately high temperatures than were plants that were not permitted to adapt

Acclimatization involve plantlets of 10-15 cm length, with shoot base of 15 mm or more distance across and sufficient attaching ought to be exchanged to pots. Planting activity ought to be finished as fast as conceivable subsequent to washing off all hints of culture media and sanitizing with expansive range fungicides (1 gl-1 metalaxil or some other fungicide arrangement 5 minutes before planting). A cleaned medium containing peat moss,vermiculite and coarse sand in the proportion 1:1:1 is perfect for soil exchange to water promptly with half Hoagland arrangement or 10% MS answer for maintain a strategic distance from lack of hydration of plants. Compartments and preparing media must be satisfactorily cleaned and sanitized. Dampness substance of the medium must be directed to least, and relative moistness of the development tub must be looked after high.

After dynamic diminishment of moistness to surrounding levels, plants are uncovered to the nursery conditions for additionally solidifying. Later the plants are exchanged to greater pots previously exchanging to nursery.This imply that Acclimatization should be done before solidifying plant and hence, hardening is to be done in the last advance for the exchange of the plant to the soil for solidifying the plants harder.
