Приведены результаты изучения влияния сроков посева семян груши обыкновенной (Pirus communis L.), лохолистной (Pirus elaeagrifolia Pall), иволистной ( Pirus salicifolia Pall) и груши Бретшнейдера (Сян-Ли, Мин-Юэ- Ли, Цзы- Ли, Чан-Бай- Ли) на всхожесть и рост сеянцев в школе сеянцев в условиях предгорной части Крыма. Определено, что оптимальным сроком посева семян груши лохолистной и иволистной является третья декада октября груши Бретшнейдера первая половина ноября семена груши обыкновенной лучше сеять в февральские окна, которые присущи погодным условиям полуострова. При выполнении сроков посева всхожесть семян составляет 45 53 6772 85 соответственно, при этом большая часть растений соответствует стандартам, т.е. диаметр условной корневой шейки составляет 410 мм.The paper summarizes study findings on the influence of seeding time on germination and seedlings growth in a nursery in the conditions of piedmont part of Crimea for common peer (Pirus communis L.), oleaster pear (Pyrus elaeagnifolia Pall), willowleaf pear (P. salicifolia Pall) and Bretshneider pear (Syan-Li, Min-Yue-Li, Tsy-Li, Chan-Bay-Li).The study determined the third decade of October to be the optimal planting time for Pyrus elaeagrifolia Pall and Pyrus salicifolia Pall for Bretshneider pear, the best planting time is the first decade of November for Pyrus communis L. the best planting timeframe is February windows (a period of warm weather in February typical for the climate of the peninsula). The timeliness of the seeding ensures seed germination at45 53 6772 85, respectively. Furthermore, the majority of the plants develop up to standard, specifically: the diameter of the nominal root collar makes 410 mm.

Seed germination performance test of Taherpuri onion (a local variety of onion) under six different temperatures (15, 20, 25, 30, 35 and 40°C) was the main goal of this experiment. Germination percentage (GP) was calculated at highest 60.25% at 25°C, and the highest germination rate 20.08 was observed in the same temperature condition. The lowest germination performance (13.25 % germi-nation and 3.32 seeds per day as germination rate) was found at 40°C temperature. Finally, the authors mentioned the temperature 20 to 30°C as optimum range, and suggested the temperature 25°C as best suited for obtaining highest results in case of both germination percentage and germination rate of these seeds. To produce maximum seedlings of the local variety of onion, the mentioned temperature should be followed by the local farmers.
