چکیده

Abstract Cover crops planted in the offseason are subjected to uncontrollable weather variables that limit agro‐ecological services through modifications growth and development. The of five cover crop species was investigated response an array day/night temperatures, 17/9, 22/14, 27/19, 32/24, 37/29 °C. Shoot root parameters were measured 33 d after planting. Quadratic functions best described most shoot dynamics increasing temperatures except for a linear plant height crimson clover ( Trifolium incarnatum ) mustard Brassica juncea ). Temperature minimum (Tmin), maximum (Tmax), optimum (Topt) traits varied from 9.8 10.6, 37.5 43.2, 23.9 26.5 °C, respectively. Tmin significantly, ranging 8.5 10.8 Topt Tmax ranged 22 25.7 35.2 40.6 On average, significantly lower than four species. Regardless recorded higher biomass partitioning (62%) root, with proportion partitioned Mighty Mustard Pacific Gold (80%) other (64–70%). results this study will help growers choose mixes same temperature range climatic conditions during fallow periods. cardinal functional algorithms developmental could be used develop models under different conditions.

Plastic Relationships between Reproductive and Vegetative Mass in Solidago Altissima.

To test several predictions of a model of linear, size-dependent reproductive output in plants, we analyzed the relationship between shoot vegetative (v) and reproductive (r) mass in five experiments on Solidago altissima from an invading population in Switzerland. There was large environmentally-induced and genetic variation in r and v. A large amount of variation in r could be explained by va...
