Description The present investigation entitled “STUDIES ON THE PROPAGATION OF KARONDA (Carissa carandas L.)” was carried out during August 2012 – December 2012 at Agricultural Research Institute, Rajendranagar, Hyderabad. A set of two experiments were carried out to study the seed germinability and effect of sucrose and plant growth ragulators on rooting of karonda cuttings in Randomized Block Design.
First experiment entitled studies on seed vaibility/ germinability of karonda comprised of seven treatments viz., zero days of extraction, 10 days of extraction, 20 days of extraction, 30 days of extraction, 40 days of extraction, 50 days of extraction and 60 days of extraction and replicated thrice. The karonda seeds were extracted from fruit and after shade drying seeds were kept in butter paper bags and stored at ambient temperature except first treatment where seeds are sown immediately after extraction. These stored seeds were taken for further seed germination studies.
The second experiment, effect of sucrose and growth regulators on rooting of karonda cuttings comprised of nine treatments viz., 2%, 4% sucrose, 7000, 8000 and 9000 ppm IBA, 1000, 2000 and 3000 ppm NAA and control/water dip which were replicated thrice. Treated cuttings were planted in polybags kept in shade condition and analyzed for various growth parameters.
The results on seed germinability revealed that seeds sown at zero days of extraction recorded maximum germination percentage followed by seeds sown after 10 days of extraction. Also minimum days taken for initiation of germination, days taken for 50 percent germination, days taken for completion of germination, maximum shoot length, number of leaves, root length, number of roots, fresh weight of shoot, fresh weight of root, dry weight of shoot, dry weight of root, root to shoot ratio, vigour index –I and vigour index II parameters were recorded in same treatment (T1) followed by 10 days after extraction (T2).
The increase in period of storage after extraction of seed from fruit resulted in loss of vaibility and vigour parameters and after 60 days of extraction (T7) only 20.33 % germination was recorded. However, seeds sown after 10 days of extraction (T2) maintained good vigour than other treatments therefore karonda seeds could be stored at ambient condition for 10 days after extraction without much variation in growth parameters.
Results of experiment on rooting of cuttings revealed that among different treatments IBA 8000 ppm recorded highest rooting percentage and lowest rooting was recorded in control.
As the successful rooting of cuttings is determined both by number of roots formed and by root elongation and growth. Therefore it is concluded that IBA 8000 ppm was best in rooting performance of karonda cuttings followed by IBA 9000 ppm and 4% sucrose compared to control.
