Abstract
ALBINO seedlings, that is, seedlings lacking chlorophyll, are observed in varying degrees in citrus seed beds according to variety. In sweet lime 30 per cent or more of the young seedlings may be albino. This lack of chlorophyll is attributed by some botanists to infection with an unknown disease. Treating citrus seeds before planting with mercuric disinfectants such as ‘Ceresan’1 and ‘Agrosan’2 resulted in the production of seedlings which with the former were nearly all and the latter all green. In this study albino seedlings were grafted on to green seedlings to see whether chlorophyll formation would be blocked in the latter as a result of possible transmission of the disease which is suspected to cause albinism or whether chlorophyll formation could be induced in albino seedlings.
