Title : EFFECT OF SHORT HOT WATER TREATMENT ON BUD GERMINATION IN

Author : T.D.Krishnamurthy, Harlapur and V.B.Kembhvi.

Year :1990-91

This project is carried out during July 1990 with the objective of studying the effect of different temperature and time interval levels on bud germination A completely randamised block experimental design was adopted. Twelve treatments with apparantly healthy canes of variety Co 740 were included. Each treatment received a grass plot size of 18 m2. Germination count was recorded at 10, 20, 30 and 40 days after planting. The final germination count data at 40 days is taken for statistical analysis. The treatments and results are presented in Table 5 and 6.

Conclusions:

a. Among the hot water treatments, treatment 2. i.e. 46 oC for 30 min. recorded significantly higher percent bud germination (67.5) which is on par with treatments 1, 3 and 4.

b. Treatments 5, 6, 7, 8, 9 and 10, 11 were on par.

c. Significantly lowest percent bud germination (28.5) recorded by treatment 12. as compaired to the remaining treatments.

d. Results revealed that higher temperature cupled with longer treatment time interval reduces bud germination considerably.
