Pot experiments were conducted in 2000-2001 and 2001-2002 seasons in
the wirehouse of the Central Laboratory for Food and Feed, Agriculture Research
Center. Giza. Egypt to study the tolerance of flax plant to different levels of salinity (0,
2000. 4000 and 6000 ppm} as 2 NaCl : 2 CaClz : 1 M980... in addition to study the
effect of different treatments: phosphorein 10 gikg seed (biotertilizer) with full or half
dose of P205. cotngein (15 9k seed) and foliafeed C (0.? g/l), (micronutrients
fertilizer compounds). GA; (at the rate of 100 ppm). on reducing the hazard effects of
salinity on growth. seed yield and chemical composition of flax plant. The obtained
results indicated that. increasing salinity levels lead to decreases in most of the
studied characters {shoot height. dry weights of roots, stems. leaves as well as whole
plant. number of capsulesrplant. number of seeds! capsule. number of seedsfplant
and seed yieldiplant as well as chlorophyll a. b and total, oil percentage and
unsaturated fatty acid). While leaves number and total leaves areai‘plant increased
significantly with salinity levels of soil from zero 4000 ppm and decreased aflerthere.
On the other hand. the application of phosphorein with full dose of P205 surpassed
phosphorein with half dose of P205 on growth. seed yield and chemical composition
under saline or non-saline soil condition. Moreover, cotngein seed coated surpassed
foliaieed C foliar application on the most of the studied growth and seed yield
characters as well as chemical composition under saline or non‘saline stress.
Furthermore, GA; at the rate of 100 ppm may correct. to extent, the negative ettect of
salinity on growth. yield or chemical composition.
