A coupled model of leaf photosynthesis and stomatal conductance as a function of photosynthetically active radiation (PAR), CO2, leaf temperature, relative humidity, and leaf age was calibrated for rose leaves. The photosynthetic parameters: maximum carboxylation rate (Vcmax), potential rate of electron transport (Jmax), rate of triose phosphate utilization (TPU), and leaf dark respiration rate...

Rose plants (Rosa x hybrida L. CV. Kardinal, grafted on Natal Brier) were grown in UC mix and in coconut coir. Water release curves and hydraulic conductivity of the media were measured. Water tensions in the media were maintained within a predetermined narrow range by tension-actuated irrigation, using high-flow electronic tensiometers. Transpiration rate of plants sitting on load cells was me...

Matematika dan budaya merupakan dua hal yang memiliki keterkaitan sangat erat, karena matematika ilmu digunakan untuk menyelesaikan masalah dalam kehidupan sehari – hari sedangkan kebiasaan dihayati dihidupi oleh masyarakat di tempat daerah tertentu sebagai satu pedoman hidup bersama. Keterkaitan antara dikenal dengan istilah etnomatematika. Etnomatematika tumbuh berkembang budaya. Dengan mener...
