Description The present pot culture experiment “Studies on the effect of salt and VAM fungi on growth of juice and table grape cultivars” was carried out at Grape Research Station, Rajendranagar, Hyderabad from November 2012 to May 2013. The study was conducted under two experiments viz., “Effect of salt and VAM fungi on growth of table grape cultivars” and “Effect of salt and VAM fungi on growth of juice grape cultivars”. The experiments were carried out in Completely randomized factorial design with four replications.
This experiment was conducted with the following objectives 1) To study the influence of varying levels of NaCl on juice and table grape cultivars 2) To identify salt tolerant juice and table grape cultivars and 3) To study the influence of VAM fungi in enhancing salt tolerance in juice and table cultivars of grape. In an attempt to achieve this, three table grape cultivars viz., Thompson Seedless, Madhu Angoor and Kishmish Rozoviz under different water salinity levels (control, 18 meq/L and 36 meq NaCl/L), were imposed with two treatments: (1) control (without mycorrhiza) (2) inoculated with VAM (Vesicular Arbuscular Mycorrhiza).
It was observed that in Madhu Angoor the morphological parameters like shoot length, number of leaves, root length, root volume, shoot dry weight, root dry weight , root to shoot ratio were significantly high indicating their vigor followed by Thompson Seedless. Physiological parameters like chlorophyll ‘a’, total chlorophyll, relative water content (RWC) were also significantly high while specific leaf weight, Na+ - K+ ratio recorded less in Madhu Angoor followed by Thompson Seedless whereas it was vice-versa in Kishmish Rozoviz. Therefore table seeded variety Madhu Angoor was identified as salt tolerant cultivar.
Similar study was conducted in three juice grape cultivars viz., Concord, Bangalore Blue and E 12/2. Among these varieties E 12/2 recorded higher shoot length,stem diameter, root length,root volume, shoot dry weight, root dry weight, root to shoot ratio and RWC while specific leaf weight ,uptake of sodium and chloride ions was least thus indicating higher salt tolerance in E 12/2 followed by Bangalore Blue and Concord.
The mycorrhizal inoculation is capable of alleviating the damage caused by salt stress in both table and juice grape varieties by way of significantly increasing the shoot length, number of leaves, leaf area, root length, root volume, shoot and root dry weight, through enhancing relative water content, K+ uptake and by exclusion of toxic ions like sodium and chloride. VAM fungi inoculation is thus helpful in salt affected soils.
