Abstract
An experimental study was investigated to estimate an interactive effect of environment on the morphological, biochemicaland phytochemical characters of Triticumaestivumviz; Aas-2011, Bakhtawar, Chakwal, Faisalabad-2008 and Galaxylines in region Khuiratta (District Kotli) having different microclimatic conditions. The results conferred that among all the five wheat varieties the maximum plants height was (73.20cm) in Chakwal and (85.60cm) in Aas-2011 without stress salinity and it was (60.32cm) in galaxy and (70.30cm) in Faisalabad-2008 under stress salinity. The peduncle length was (65cm) in Bakhtawar and (85cm) in Galaxy without using salt. The peduncle length was (50cm) in Bakhtawar and (75cm) in Faisalabad-2008 after salt while, spike length was (4.30cm) in Bakhtawar and (9.5cm) in Aas-2011 before applying salt and after applying salts the spike length was (3cm) in Bakhtawar and (7.5cm) in Aas-2011. Number of spike/spikelet’s before applying salt was (10.60) in Bakhtawar and (50.60) in Aas-2011. Number of spike per spikelet was (5.50) in Bakhtawar and (45.50) in Aas-2011 stress salinity. The number of grains/spike was (9.33) in Bakhtawar and (48) in Aas-2011 before applying salts while it was (6.40) in Bakhtawar and (38) in Aas-2011 respectively after applying salt. Flag leaf weight was (0.15gm) in Bakhtawar and (0.37gm) in Galaxy before using salts. Whereas flag leaf weight was (0.09gm) in Bakhtawar and (0.30gm) in Galaxy after applying salts. The leaf area was (8.40cm) in Bakhtawar and (9.50cm) in Chakwal without stress salinity, it was (6.30cm) in Bakhtawar and (7.80cm) in Chakwal under stress salinity. Similarly, grain yield (1.05gm) was in Bakhtawar and (2.30gm) in Aas-2011 without using salts, while it was (1gm) in Bakhtawar and (2.10gm) in Aas-2011 under stress salinity. The soil parameters analyzed included saturation percentage (36%), pH (6.8), E.C(0.40ms), organic matter (0.80), K(90ppm), P(8ppm), respectively. To evaluate the genetic diversity in the seed endosperm of Triticumaestivum for the nutritional grading by using SDS-PAGE. Five bands were attained by using 10 to 180kDa (Asbastas/SM0661), among which the band B, F and A with molecular weights 180kDa, 95kDa and 43kDa respectively were common in five wheat varieties but other band, show little variations. Wheat grouped in some cluster analysis which showed their initiation from same parental line so these are genetically less variance.
