Title

AN INVESTIGATION OF EFFECT SEED SOURCE, DIAMETER OF MOTHER TREE AND PERIOD OF TREATMENT ON SEED GERMINATION OF WILD SERVICE (SORBUS TORMINALIS ( L.) CRANTZ ) SPECIES IN MAZANDARAN

Pages

  215-224

Abstract

 In this study, the GERMINATION percentage, the start time of GERMINATION ( MT1), ,the final time of GERMINATION( MT2), seed viability index of SORBUS TORMINALIS from different SEED SOURCE during two years preservation in normal refrigerater conditions and comparison with the first year preservation were studied. The SEED SOURCE namely Pasand, Sangedeh and Ashek in Mazandaran Province were selected for this research. The results showed that the effect of SEED SOURCE was only significant on MT1 and MT2.The survey of seed preservation time has shown that the effect of seed preservation time was significant on GERMINATION percentage and MT2. The MT2 has also respectively increased to 28.2, 23.2 and 31.8 days for Pasand, Sangedeh, Ashek sources. The result indicated that trees with difference diameter have significant difference in seed GERMINATION , so that , trees in 40 cm diameter classes (35< x <45 ) have the most seed GERMINATION and trees with more than 55 cm diameter and less than 35 cm diameter have the lowest seed GERMINATION . Generally, from this examination, it can be deduced that, there are variation (between and within population) in the seed characteristics of SORBUS TORMINALIS from populations. It’s also recommended that to collect seeds for gene bank, we should avoid from preserving them in refrigerator more than one year. Also, it can be deduced that seeds of tree with 36-55 diameter range more GERMINATION than other trees.
