چکیده
گونه لاتی (Taverniera spartea) یکی از گونه‌های مهم مراتع خلیج و عمانی است. در این پژوهش، برخی از نیازهای اکولوژیک گونه لاتی و پاسخ آن‌ها به عوامل خاکی و توپوگرافیکی در سه رویشگاه اصلی در استان هرمزگان (سیاهو، احمدی و بشاگرد) تعیین شد. نتایج نشان داد که درصد پوشش در سطح یک درصد و درصد خاک لخت و درصد سنگ و سنگریزه در سطح 5 درصد معنیدار بود. بکارگیری مدل جمعی تعمیم‌‌یافته، برای هر یک از متغیرهای محیطی، نشان داد که متغیرهای درصد آهک خاک، درصد رس، اسیدیته، درصد کربن آلی خاک، ازت خاک و درصد خاک لخت بر عملکرد گونه، معنیدار می‌‌باشند. افزایش درصد رس خاک از مدل کاهشی، افزایش اسیدیته خاک، از حالت دو مد، افزایش مقدار آهک خاک و همچنین مقدار درصد خاک بدون پوشش، از مدل زنگوله‌ای، افزایش درصد کربن آلی و ازت خاک هر دو از مدل افزایشی پیروی کرد. بررسی فنولوژی گونه نشان داد که رویش این گیاه از دهه دوم آبان‌‌ماه شروع می‌‌گردد و از دهه سوم اردیبهشت‌ماه وارد مرحله رکود می‌شود. باتوجه به ارزش غذایی گونه و نقش آن در حفاظت خاک مراتع، پیشنهاد می‌شود در مناطق تخریب‌شده مرتعی که شرایط استقرار آن را دارا هستند، نسبت به کاشت این گونه اقدام شود.

چکیده [English]
Taverniera spartea is one of the most important species in the Gulf and Omani rangelands. In this study, some ecological needs of Taverniera spartea and their response to soil and topographic factors in three main habitats in Hormozgan province (Siahoo, Ahmadi and Bashagard) were determined. The results showed that the percentage of cover was significant at the level of 1% and the percentage of bare soil and the percentage of rocks and pebbles at the level of 5% was significant. Applying the generalized collective model for each of the environmental variables showed that the variables of soil lime percentage, clay percentage, acidity, soil organic carbon content, soil nitrogen and bare soil percentage on species yield are significant. Increasing the percentage of soil clay from the Monotonic decrease, increasing the acidity of the soil, from the Bimodal distribution, increasing the amount of soil lime and also the percentage of bare soil from the Unimodal and increasing the percentage of organic carbon and soil nitrogen from the Monotonic increase followed. The phenological study of the species showed that the growth of this plant starts from the second decade of November and from the third decade of May, enters a stage of stagnation. Considering the nutritional value of the species and its role in the protection of rangeland soil, it is recommended to plant this species in the degraded rangeland areas that have the conditions for its establishment.
