Anthers dehisce longitudinally. Anther dehiscence commences 24 hr. before anthesis, peak being immediately after anthesis. Pollen grains have mean diameter of 16.1/* and are triangular in shape with three furrows and the apertures fused to form a ring. Maximum pollen germination and tube growth obtained in 1% sucrose+0.01% boric acid, germination starting 33 hr. after dusting. The stainability of pollen was 81%. Stained pollens were larger in size and gave higher percentage of germination. Stigmatic receptivity was maximum on the day of anthesis and the following day. Under artificial pollination, the maximum fruit set obtained was 30%, while under bagged conditions, it was 28%. Self pollination appeared to be more probable in clove.enclovefloral biologyArticle
