Physiological Quality of Kochia (Kochia scoparia (L.) Roth) Seed under Different KCl Salinity Levels. The demand for improved seeds for the establishment of forage crop grasslands have increased in recent years. However, the limited availability, low yields, and poor seed quality have made it a difficult task. The aim of this study was to evaluate the effect of different salinity levels of KCl solutions on seed physiological quality of kochia (Kochia scoparia (L.) Roth). The work was conducted under laboratory and greenhouse conditions, using Kochia seed harvested and packed in 2007. The evaluated treatments for both conditions were six saline solutions of KCl, equivalent to 0, 5, 10, 15, 20, 25 and 30 ds m-1, besides the witness with distilled water. The variables studied were Germination capacity of its components: Normal plants (PN), Abnormal plants (PA), Non-germinated seeds (SSG), Vigor, Speed germination index (IVG), Speed of emergence index (EVI), Average hypocotyl length (LMH) Average radicle length (LMR) and Seedling dry weight (PSP). A completely randomized design was applied and data were analyzed using the software SAS, Ver. 6.0. The witness showed the best germination capacity (P<0.01), with the highest percentage of PN, and the lowest of PA and the least amount of SSG. The amount of PN was directly proportional to the level of salinity, and PA, and SSG amounts were inversely proportional. The witness showed, also, the highest values in IVG, PC, LMH and LMR, so it may be concluded that, in both environments, increasing salinity levels of KCl solutions directly affects the germination and vigor of kochia seed, since the amount of non-germinated seeds and abnormal seedlings are increased. A salinity level of 5 and 10 ds m-1 can increase the length of the seedlings hypocotyl ensuring the rapid establishment of them as a crop.
