title: BIOMETRIC INDICES OF POLLEN FROM NATURAL POPULATIONS OF &lt;i&gt;PINUS BRUTIA&lt;/i&gt; VAR. &lt;i&gt;PITYUSA&lt;/i&gt; (PINACEAE) OF THE CRIMEAN MOUNTAINS
abstract: The study of biometric characteristics of Pinus brutia var. pityusa pollen was carried out in natural populations of P. brutia var. pityusa in the Crimean Mountains. The pollen was collected during the period of its free flight on sample plots along four hypsometric profiles. In the western part of the southern macroslope of the Main Ridge of the Crimean Mountains on Cape Aya in the Ayazma tract, 3 sample plots were laid at altitudes of 50–290 m above sea level, in Batiliman – 2 plots, at altitu
