ABSTRACT

The purpose of the investigation was to study the early spring plant diversity distributed in different vegetation types and their life forms, in relation to different altitudes. The investigation was carried out in accordance with itinerary method beginning from the shoreline up to the mountain. The results showed that 100% of the totally collected plants from the desert vegetation were therophytes; 100% from steppe vegetation were geophytes; 50 from forest were geophytes and the other 50% were hemicryptophytes. It is concluded that the life forms of early spring plants change depending on the altitude corresponding to changes in the air temperature as well as climatic and edaphic factors.

Keywords: Climate changes; ephemerals; geophytes; life form of plants; transect

ABSTRAK

Tujuan penyelidikan ini ialah untuk mengkaji kepelbagaian tumbuhan musim bunga awal yang tertabur dalam jenis vegetasi berbeza dan bentuk kehidupannya dan perhubungan kepada altitud berbeza. Kajian telah dijalankan mengikut kaedah jadual bermula dari tepi pantai hingga ke gunung. Hasil menunjukkan 100% daripada jumlah tumbuhan yang dikumpul dari vegetasi padang pasir adalah reofit; 100% dari vegetasi steppe adalah geofit; 50% dari hutan adalah geofit dan 50% yang lain adalah hemikriptofit. Ia boleh dirumuskan bahawa bentuk kehidupan tumbuhan awal musim bunga bertukar bergantung dengan altitud berkenaan kepada perubahan suhu udara dan juga faktor edafik dan iklim.

Kata kunci: Bentuk kehidupan tumbuhan; efemeral; geofit; perubahan iklim; transek
