| dc.description.abstract | A study of total numbers of leaves, spadices, female flowers, numbers of female flowers per bunch and flowers set was carried out in coconuts. The trees were grouped as high yielders (over 80 nuts per tree per year), medium yielders (40 to 80 nuts per tree per year) and low yielders (less than 40 nuts per tree per year). Each group was subdivided into regular bearers (C.V. 30 per cent or less) and irregular bearers (C.V. over 30 per cent). The production of spadices was greater in regular bearers than in irregular _ bearers, and the difference was accounted for by the abortion of spadices in irregular bearers. The abortion of spadices may be linked with the effect of drought on the less well developed root system of irregular bearers and seemed to be the main cause of irregularity in yield of all three yield groups. There was no significant difference in the number of female flowers per bunch in regular and irregular bearers. A positive correlation was found between yield and female flower production except when female flower production was high. The variation in female flower production appeared to be related more to the number of opened spadices than to the number of female flowers per bunch. | en_US |
