Plants that received the least amount of water did not grow as well
as plants that received relativelymore water indicating thatwater stress
was applied. In bothwatering regimes (Table 1, Fig. 1), the leaf drymass
production of all test plants decreased significantly (P ≤ 0.05) with a reduced
water supply. Especially in the case of B. frutescens, there was a
linear dose response (R2 = 0.98) between dry mass yield and water
supply (Fig. 1). The results in general suggest that the selected water
supply levels did indeed lead to water stress in all cases suggesting
that plants were affected by it. These results are consistent with those
of other studies
