Pecan Bud Growth and Freeze Damage are Influenced by Rootstock

Damage by Early Autumn Freeze Varies with Pecan Cultivar

Pecan [Carya illinoinensis (Wangenh.) C. Koch.] trees were injured by freezing temperatures in Oct. 2000, occurring about 4 weeks before the average first freeze and 6 weeks before the normal killing freeze (less than or equal to –2 °C). Nonbearing and bearing cultivars were rated for injury at four sites the following May. Nonbearing cultivars with little or no damage included ‘Caddo’, ‘Clark ...

Tree Spacing and Rootstock Affect Growth, Yield, Fruit Quality, and Freeze Damage of Young 'hamlin' and 'valencia' Orange Trees

A citrus spacing experiment begun in 1980 included 4 spacings, 2 varieties, and 2 rootstocks. Planting densities ranged from 150 to 360 trees per acre with spacings from 8 x 15 ft to 15 x 20 ft. 'Hamlin' and 'Valencia' Sweet orange (Citrus sinensis (L.) Osb.) trees were planted on Milam lemon ( C. jambhiri Lush) and Rusk citrange ( Poncirus trifoliata (l.) Raf. x C. sinensis) rootstocks. Trees ...

Growth cones are actively influenced by substrate-bound adhesion molecules.

As axons advance to appropriate target tissues during development, their growth cones encounter a variety of cell adhesion molecules (CAMs) and extracellular matrix molecules (ECM molecules). Purified CAMs and ECM molecules influence neurite outgrowth in vitro and are thought to have a similar function in vivo. For example, when retinal ganglion cell (RGC) neurons are grown on different CAM and...

Growth, Yield and Quality of Rosa hybrida L. as Influenced by NaCl Salinity

The effects of sodium chloride (NaCl) salinity (control; canal water with 0.4 dS m-1), 2.5 dSm-1, 5.0 dS m-1, 7.5 dS m-1 and 10.0 dS m-1, respectively) developed after 6 weeks of pruning (beginning of study) on plant growth, flowering and quality of three cut rose (Rosa hybrida L.) cultivars viz. ‘Kardinal’, ‘Angelique’ and ‘Gold Medal’ were studied to achieve better management, quality product...
