INFLUENCE OF GROWTH STIMULANTS RIBAV-EXTRA AND EPIN-EXTRA ON THE GERMINATION OF SEEDS OF KHINGHAN FIR (ABIES NEPHROLEPIS (TRAUTV.) MAXIM.)

Khinghan fir (Abies nephrolepis (Trautv.) Maxim.) is the most common species among conifers of Primorsky Krai. It plays an important role in forest consumption. However, fires and logging lead to a reduction range this species. Thanks use growth stimulants, it possible accelerate restoration Far Eastern fir. The aim research was study effect stimulants Ribav-Extra Epin-Extra on germinative energy, laboratory seed germination morphometric parameters sprouts (length weight) Maxim.). According GOSTS, experiments were carried out four repetitions seven different concentrations solutions (1×10-3 – 1×7×10-3 ml/l). Control − seeds soaked distilled water. length measured with electronic caliper. mass weighed balance. conducted studies showed, that had greatest sowing qualities (germinative energy germination) at solution 1×2×10-3- ml/l, amounting 4-16% (excess control 21.2-384.8%). For (21.4-33.1%) 1×3×10-3-1×6×10-3 ml/l 127.7-252.1%). showed more active 1×2×10-3-1×6×10-3 4-16%. Excess 21.2-384.8%. concentration 1×3×10-3 - 1×5×10-3 positive (13-33%), exceeding by 38.3-251.1%. An increase quality classes noted: from third second first. These also proved be effective for increasing biometric weight). Thus, significant noted 1×10-3-1×6×10-3 7.7-50%); 1×4×10-3-1×7×10-3 7.7-40%. all 5.1-79.5%). less effective.
