| Abstract:
Plant growth has certain relationship with albinism disorder, which is considered as the most serious disorder of strawberry fruits. Albino fruits appear bloated, develop poor colour, and fetch poor price in the market. Studies were, therefore, conducted with three mulches viz. black polyethylene, white polyethylene, and paddy straw in 10 cultivars to observe the incidence of albinism in different cultivars grown in subtropical climate and whether or not different mulch materials affect plant growth and albinism disorder and to establish relationship between plant growth and albinism disorder in strawberry. Observations indicated that nearly 33 per cent fruits were affected by albinism. Further, all plant growth parameters viz. crown height, leaf number and leaf area were influenced by different mulch materials. Interestingly, the incidence of albinism was the highest (38.6%), with black polyethylene and the lowest with paddy straw (22.5%). Among cultivars, Etna had the highest incidence of albinism (50.6%), followed by Chandler (44.6%), a variety grown on a large scale under subtropical climate, and Sweet Charlie had the least incidence of albinism (22.5%), which has recently been recommended for commercial growing under subtropical climate. | |
