“…6) makes it likely that splatters caused by rain drop impact are highly saline when rainfall amounts are limited. Leaf-induced damage often increases with increasing humidity (Grattan et al, 1981;Moser, 1975) as it provides a longer time for foliar salt absorption.…”

Good stands of furrow irrigated onion (Allium cepa L.) are difficult to obtain in saline areas of the Southwest. This study examined salt effects on seed germination, emergence, and seedling mortality of five onion cultivars in a series of greenhouse experiments at diurnal temperatures of 15 to 25 °C. Germination exceeded 80% within 10 d at solution salinity of 20 dS m−1 or less. Cultivar effects on germination appeared initially, but diminished after approximately 1 wk. Seedling emergence from potted and subirrigated loamy sand declined significantly when salinity of irrigation water exceeded 4.9 dS m−1. This decline was apparently caused by hypocotyl mortality when the cotyledon came into contact with the salts accumulated at the soil surface, but not by reduced seed germination. Soluble salts accumulated mostly within the top 5 mm of the soil and the accumulation below 5 mm was minimal. The removal of the salted surface layer improved seedling emergence. Leaching of the surface‐accumulated salts into the seedling root zone 3 wk after seeding resulted in seedling mortality of significant magnitude; 12 and 20% in seedlings previously subirrigated with solutions of 2.8 and 4.9 dS m−1, respectively. A significant increase in seedling mortality was also observed when seedlings were sprayed twice after emergence with saline solutions of 28 and 39 dS m−1. The ability of cotyledons and seedlings to tolerate salinity, rather than the ability of seed to germinate in highly saline solutions, may be a limiting factor for obtaining good stands in furrow‐irrigated onion in saline areas.

“…The main reason for the destruction of landscape plants in parks located on the Tel Aviv coast is the damage caused by wind-borne salts (1). Foliar injury by air-borne sea salt was described and studied previously (3,4). As indicated by Boyce (2), a critical level of wind velocity of 7.0 m/sec (23 ft/sec) is required in order to create wind-borne salt.…”

Ocean spray carried by wind was shown to be the main cause of leaf scorching of vegetation along the Mediterranean coast of Israel. An overhead sprinkling system was designed to be activated when wind velocity reached a critical level. It was shown to reduce leaf scorching. The degree of protection depended on plant species. Plants showed different degrees of sensitivity to wind-borne salts in the following increasing order: Japanese Pittosporum (Pittosporum tubira Ait.), Thorny Elaeagnus (Elaeagnus pungens Thunb.), Common Oleander (Nerium oleander L.), Tamarisk, Athel (Tamarix aphylla Karst.).

“…Rich (19) in 1968 observed the same range of sensitivity to tolerance among species as had been observed in the case of coastal vegetation. Others have contributed to the literature with descriptions of salt injury symptoms (4,9,13,16), correlation between injury and salt content of plant tissues (10,11,14), and varying suscep-tibility of plants (6,12,22).…”

The Response of Dormant Norway and Sugar Maples to Simulated De-Icing Salt Spray

Norway maple and sugar maple trees sprayed during dormancy with salt solutions simulating salt spray along heavily salted roads in winter were less vigorous than those not exposed to salt. Fresh and dry weights of leaves, stems, and roots; height increase, and total shoot growth were greater in the unsalted trees. The percent of buds opened was also slightly greater on the unsalted plants. Percent dry weight was lower for the unsalted plants, indicating a higher water content than in the salted trees. Trees which were exposed to ambient conditions following the salt spray were generally in better condition than those protected from precipitation. Salt deposited on plant parts was probably washed away, preventing injury.
