Abstract
The effects of gibberellic acid, kinetin, benzyladenine, ethylene, 24-epibrassinolide, triacontanol and polyamines (cadaverine, putrescine, spermidine, spermine), alone or in combinations, on germination and early seedling growth under high temperature conditions of barley and radish seeds were studied. High temperature both delayed and inhibited the germinations of both the species. Only three of the single applications gibberellic acid, kinetin and 24-epibrassinolide could alleviate the effects of high temperature on germination of barley seeds. All the combinations composed of these three growth regulators removed more successfully this adverse effect on germination. High temperature effect on the germination of radish seeds was overcome by all the pretreatments alone or in combinations to varying degrees. Although the mentioned regulators carried on their success on the early growth of barley seedlings, the regulators used for radish had no effect on the seedlings in general.
Özet
Arpa ve turp tohumlarinin yuksek sicaklik kosullari altindaki cimlenme ve ilk fide buyumesi uzerine gibberellik asit, kinetin, benziladenin, etilen, 24-epibrassinolit, triakontanol and poliaminlerin (kadaverin, putressin, spermidin, spermin) tek basina ve kombinasyon halindeki etkileri arastirilmistir. Yuksek sicaklik her iki turun cimlenmesini hem engellemis hem de geciktirmistir. Sadece gibberellik asit, kinetin ve 24-epibrassinolit arpa tohumlarinin cimlenmesi uzerindeki yuksek sicakligin etkilerini hafifletebilmistir. Bu uc buyume duzenleyicisinden olusturulan tum kombinasyonlar çimlenme uzerindeki bu olumsuz etkiyi daha basarili bir sekilde uzaklastirmistir. Turp tohumlarinin çimlenmesi uzerindeki yuksek sicakligin etkisi tek ve kombinasyon halindeki tum on uygulamalar ile degisik derecelerde ortadan kaldirilmistir. Soz konusu buyume düzenleyicileri arpa fidelerinin büyümesi uzerinde de basarilarini devam ettirmelerine karsin, kullanilan duzenleyiciler turp fidelerinin buyumesinde genellikle etkisiz olmuslardir.
