RESPONSE OF LOCAL COMMON VARIETIES OF CLOVER TO SALINITY
ZIZY MOSTAFA ABBAS;
Abstract
Six pot and laboratory experiments were carried out in the laboratory and the Agricultural Experimental Farm of the Faculty of Agriculture, Ain- Shams University. These experiments aimed to study the effect of various concentrations of NaCl on the germination, seedling growth and development, fresh and dry forage yields and the chemical composition of the studied clover varieties.
Results of the germination tests showed that germination %, germination rate index, radical and plumule length were significantly influenced by NaCI concentrations and clover varieties. Increasing NaCI concentration up to 4000 ppm depressed significantly the germination%, germination rate index and plumule length.
The tested clover vanetles i.e. Giza I, Ismaelia 1 , Helaly, Sakha 4 , Serw I and Gemmeza I differed greatly in their response to salt treatments. Seeds of alfalfa varieties were less tolerant to NaCI than berseem varieties. Seeds of sakha 4 and Gemmeza 1 were more tolerant to NaCI treatments than other varieties.
The lowest salt concentration (500 mgrnllit) exerted a stimulative effect on the plumule length, while the highest concentration (4000 mgm!Iit) reduced the plumule length by about
42% of the control.
The effect of the interaction between clover varieties and NaCI concentrations was significant on germination %, germination rate index and both radical and plumule length.
