اثر محلول‌پاشی کلسیم بر تجمع ماده خشک و اجزای عملکرد در گیاه بزرک (Linum angustifolium) تحت شرایط تنش کم‌آبیاری

To study the effect of foliar application of calcium on dry accumulation and yield components of Linum angustifolium under water deficit stress, the field experiments was carried out in shahrood university in 2013. The experiment was split plot based on randomized complete block with with two factors and three replicates. The factors were three levels of irrigation 8 days (no stress), 12 daye (mild stress) and 16 days (sever stress) as the main factor and five levels of calcium foliar application.
The results indicated that total dry matter, leaf dry weight and dry weight capsule foliar concentration of 12 mM and mild stress conditions than under high stress were improved traits. The foliar concentrations of 12 mM calcium in mild stress conditions were improved seeds per capsule. In conditions of severe water stress during grain filling were applied at a concentration of 12 mM increased the shoot dry weight, number of capsules per plant and seed yield. The study was conducted in the range of 12 mM calcium chloride treatment combination of lack of tension applied during grain filling can be introduced as the best treatment combination.
