Abstract:

The floral biology of guava cultivars viz. Hisar Safeda, Hisar Surkha, L-49 and Allahabad Safeda was studied at horticulture farm of Department of Horticulture at CCS, Haryana Agricultural University, Hisar. Two flowering seasons, viz., spring (April-May) and autumn (August-September) were observed in all the guava cultivars under semi-arid conditions of Haryana. The duration of flowering varied from 33-41 days in the spring season while it was 38-45 days in the autumn season. The floral bud passed through eight arbitrary stages from dormant to fully opened stage and took 36-42 days to complete all the stages in rainy and winter season respectively. Seventh stage of floral bud was most suitable for emasculation. All the cultivars bore flower solitary or in cymes of 2-3 flowers on the current season growth in the axils of the leaves. The flower size of all the cultivars was found to be significant in both the season i.e. April-May and August-September. However, there was no appreciable difference in the number and size of sepals and petals with regard to cultivars and season of flowering. Greater variation was recorded in the number of stamens in all the cultivars.
