摘要: Abstract A field study of Lessonia variegata growing in depths 8–10 m on the south coast Wellington, New Zealand investigated morphometric and biomass indices measured destructively harvested entire algae, rates blade elongation situ using a hole punch technique, timing fertility over 2‐year period. Blade was estimated score based visual appearance reproductive tissue. attained maximum length 154 cm, density 0.8 to 2.1 individuals m‐2, developed an areal ranging from 1700 6000 g fresh weight (FW) m‐2. The highest proportion fertile blades (up 100% sampled blades) occurred during winter end period coincided with onset longer days warmer temperatures summer. more rapidly summer months (0.117cm day‐1, SE = 0.015) than (0.041cm 0.009). slower rate meant th...
