The effects of photoperiod, pinching, and plant growth regulators on growth and flowering of Abutilon x hybridum
<i>Abutilon</i> x <i>hybridum</i>, flowering maple has the potential to become a profitable floriculture crop. However, growing guidelines need to be developed in order to produce a proportional, well-branched, and uniform-flowering pot plant. The objective of this research project was to form a …

Aspects of Velvetleaf (Abutilon Theophrasti Medik.), Jimsonweed (Datura Stramonium L.) and Common Cocklebur (Xanthium Strumarium L.) Interference With Soybeans
Velvetleaf (Abutilon theophrasti Medik.), jimsonweed (Datura stramonium L.) and cocklebur (Xanthium strumarium L.) are broadleaf weeds common in midwest soybean fields. Cocklebur causes greater yield reductions than velvetleaf and jimsonweed at equivalent densities. Cocklebur has a greater …

A Systematic Revision of Bakeridesia Hochr. (Malvaceae)
… and several species previously included in Abutilon was removed from Bakeridesia and given the genus name Callianthe. Second, phenetic analyses of morphological data were employed to help determine species boundaries in the taxonomically difficult Bakeridesia integerrima complex; as a …

Absorption, distribution and metabolism of bifenox
… 4.5 kg/ha, preemergence application. Velvetleaf (Abutilon theophrasti Medic.), a weed susceptible to the herbicide, absorbed and translocated more ¹⁴C-bifenox during early seedling growth than corn (Zea mays L.) and soybean (Glycine max (L.) Merr.). The patterns of absorption and distribution of …

Comparative analysis of ovary development in selected members of the subtribe Abutilinae (Malvaceae)
… the basis of acropetal initiation of ovules in Abutilon species and the precocious development of style primordia in Malacothamnus fasciculatus, a mechanism for the origin of the uniovulate carpel is proposed. Here, early style growth may limit zonal growth of the gynoecial base so that the …
