Abstract
O ats (Avena sativa L.) now a days have received substantial attention for a multiple reasons i.e. high contents of dietary fibres, phyto-chemicals, nutritive value and other health benefits (Prasad et al., 2015). Oat is a dual purpose (cereal and forage) crop, and is widely planted in marginal lands China is one of the largest consumer of forage crop worldwide, with the import of oat hay of 10.39 million tons during 2017 from the United States, Australia etc. After alfalfa oats are the second largest imported forage crop Performance of oats under salinity for estimating Abstract | Agricultural yield in Pakistan is liable to environmental constraints, mainly salt and water stress due to their elevated degree of impression and non-availability of salt and drought tolerant oat cultivars. For the purpose in-vitro study was conducted at NARC fodder laboratory to study the response of two oat cultivars namely NARC and PARC Oat against drought and salinity stress. Salt concentration of 80 mmolL showed non-significant effect on germination % and shoot length of both oat cultivars except salt concentration of 120 mmolL, but tolerance in NARC, Oat is higher than PARC oat. Salt concentrations positively increased root length, except in PARC oat at 120 mmolL. Drought stress (PEG) significantly reduced the shoot length in PARC, Oat cultivar when 20% solution was applied. Where both treatments were applied in combinations to measure the drought and salinity tolerance at initial seeding stages of both oat cultivars, no significant effect was observed on germination %, shoot and root length of both oat cultivars, however PARC, oat performs better at 10 % and 20 % drought stress with salinity level of 80 mmolL. However, both cultivars showed significantly stunted performance at 10 % and 20 % drought stress with salinity level of 120 mmolL when compared with control treatment. The results of the study present the potential resistance of NARC oat against salinity and PARC oat against drought stress. This study will helps in selection of salt and drought tolerant oat cultivars for the affected areas.
