Abstract : Various measures were used with 4-month-old, wild mango rootstocks to reduce cold damage, namely straw mulching, irrigation, weeding and hoeing, weeding and irrigation, or covering with thatch, black polyethylene or gunny cloth. Covering the rootstocks with thatch or black polyethylene, from early Dec. to mid Mar., greatly reduced cold damage to 13% mortality and 21% foliage damage in both cases, compared with the control at >49% mortality and foliage damage. Seedling growth was significantly higher with thatch, black polyethylene or gunny cloth. A straw mulch dramatically increased damage to >67% mortality and >69% foliage damage. Damage was greatest when the temperature was 2.8°.
