ZNAČAJ POZNAVANJA MORFOLOŠKIH PROMENA U TOKU RAZVOJA AHENIJA - "SEMENA" BELE LIPE (Tilia tomentosa Moench.) ZA ODREĐIVANJE VREMENA BRANJA I SETVE
THE IMPORTANCE OF RECOGNIZING THE MORPHOLOGICAL CHANGES DURING THE DEVELOPMENT AHENIA SEED OF WHITE LINDEN (Tilia tomentosa Moench.) FOR THE TERM DETERMINATION OF ITS PICKING AND PLANTING
The diferent useful function of white linden and its profitable worth are arguments that should be the spread and encourage plantation this species by generative way. The problems which appear during plantation are caused by dormancy its seed, and the method of stratified treated seed done the variable results we studed a predormant period. By a plantation the inmature seed Tilia tomentosa above mentioned arouzed problems were considerably exceeded. This paper shows the morphlogical characteristics in the seed development with the help of wich it is possible to determin unoptional term for picking and seed plantation in its inmature stadium. Applying in practice this method it is possible to increased productiviti and racionalization of the seeding production of white linden in the nurseries production.
Opšte korisne funkcije bele lipe i njena upotrebna vrednost su razlozi zbog kojih treba omasoviti proizvodnju ove vrste generativnim putem. Problemi koji se javljaju u procesu proizvodnje su vezani za dormantnost njenog semena, a postupci stratifikacije su dali varijabilne rezultate. Setvom nedozrelog semena mnogi od problema su prevaziđeni. Ovaj rad otkriva morfološke karakterislike u razvoju semena pomoću kojih se određuje optimalno vreme branja i setve semena na zeleno što u praktičnoj primeni ove metode povećava produktivnost i racionalizuje proizvodnju sadnica bele lipe u rasadnicima.
