The study was carried out at Tishreen University nursery during the spring of 2015
in order to evaluate the effect of the bio-fertilizer EMI on the growth and production of
Sponta Potato Solanum tuberosum. Four treatments were used as follows: cont
rol, with
water irrigation, spraying and irrigation, spraying.
The results showed that the use of bio-fertilizer EMI improved the growth of plants,
so the surface foliage, foliage index and plant height were increased significantly
comparing with the control.
The results also showed that the spraying and irrigation treatment was the best with a
tuber average weight of 117.7 g/tube obverse (102.7, 115, 109 g/tuber), and a yield of
5864 kg/d obverse (4151, 5569, 5398 kg/d) for treatment (control, water irrigation,
spraying).

Experiments were conducted to study effect of radiation and salt levels on plant
regeneration from callus for two cultivars of potato i.e. Riviera and Burren, under
in vitro condition. Results showed that the efficiency of radiation in induced
reg
eneration from callus in Riviera cultivar at salt level of (10 dS m-1) and Burren
cultivar at salt levels (8, 12 dS m-1). For the purpose of making sure inheritance
of salinity tolerant, mutant clones (plants induced from salt tolerant calli, which
planted at salt levels of 8, 10, 12 dS m-1 and plants induced from non salt tolerant
calli, which planted at salt level of 6 dS m-1) and their parental cultivars (Riviera
and Burren) by exposing to salt stress conditions and comparing them with control
(6 dS m-1). Results revealed that the lowest percentage of reduction in plant height,
number of nods per plant and tuberization were observed in salt tolerant mutants.
Plant height and number of nodes/plant can be considered as selective morphological
markers for in vitro salt tolerance .
Marfona cultivar were chemical mutagen using 20, 30 and 40 mM of Ethyl Methane
Sulphonate (EMS) for 2, 3, 4 hrs in 2013. was conducted to improve potato (Solanum
tuberosum L.) tolerance to salinity. Plants Marfona mutagen from M5 and unmutagen were
cultured with Spunta and Falouka Cvs in 2015. Plants were later subjected to another
selection pressure, by irrigating them using water containing Nacl between 0-200 mM The
results showed that the gradual increase in Nacl concentrations caused a significant gradual
decreases in most vegetative, yield and its component characteristics. Mutant plants varied
with unmutant for Marfona, Spunta and Falouka in plant height varied from 68 to 41 cm
and number leaves varied from 21 to 12 leaf. and stem diameter varied from 1.349 to 0.370
cm and leaf area varied from 235 to 84 cm2. However, produced tubers number varied
from 9.3 to 2.8 and weight them from 740 to 155 grams and tuber weight from 75.2 to 24.6
grams.
The results also showed variations in the extent of tolerance between studied
treatments to salinity stress where 4T3P2 treatment was the most tolerant.
