An experiment was conducted to determine the influence of several synthetic mulches and one biodegradable mulch on the yield of `Crimson Sweet' watermelons. The experimental design was a randomized block design using VisPore rowcover and various mulches. The results showed that using brown mulch resulted in a significant increase in marketable numbers of watermelons. Total yield of watermelons showed significant row cover × mulches interaction. Higher yields were observed with brown mulch and VisPore rowcover. The total number of watermelons grown with mulches was significantly greater than the control.

Rye, wheat, and crimson clover were planted in separate pots outdoors in the fall of 1992 and 1993 Control pots had media without plants in them. There were 4 replications in 1992 and 9 in 1993. In early spring. the rye, wheat, and crimson clover were killed, using tillage in 1992 and glyphosate in 1993. In 1992. the residues were tilled into the media. In 1993, the residues were left on the surface. `Cardinal' strawberries, yellow nutsedge nutlets, crabgrass seeds, or bermudagrass rhizomes were planted into pots with the various residues, and also into the control pots. In July of 1992 and August-September of 1993, the weeds and strawberry plants were removed from the pots. Various growth measurements were taken on the plants. None of the tilled residues affected the growth of nutsedge or crabgrass, but tilled rye and wheat residues increased the growth of strawberry plants and decreased the growth of bermudagrass. None of the residues left on the surface significantly affected the growth of crabgrass. Clover residues suppressed nutsedge growth Both strawberry and bermudagrass growth was greatly reduced by all surface residues

The effects of BA concentration on flowering and dry-matter partitioning in shoots of `Crimson Giant' Easter cactus [Rhipsalidopsis gaertneri (Regel) Moran] were investigated. Treatments were applied 12 days after starting the forcing phase (before flower buds were visible) and included BA at 0, 10, 50, 100, and 200 mg·liter–1. Relative to the controls, BA increased the total number of flower buds per plant and delayed flowering by 2 to 3 days. The percentage of aborted flower buds increased more than 3-fold as BA concentration increased from 0 to 50 mg·liter–1 and increased further when 100 or 200 mg·liter–1 was applied. The number of flower buds that reached anthesis increased quadratically with increasing BA concentration and was maximal when plants were treated with 50 mg·liter–1. As BA concentration increased from 0 to 200 mg·liter–1, total dry weight of phylloclades decreased, whereas dry weight of floral tissue increased by a nearly equivalent amount. BA increases flowering and alters partitioning of dry matter in reproductive plants of `Crimson Giant'. Chemical name used: N-(phenylmethyl)-1H-purine-6-amine (BA).

Crimson clover Trifolium incarnatum L.) was used as a N source for sweet potato [Ipomoea batatas (L.) Lam.]. Treatments were designed to compare estimated N delivery by clover incorporation amounts of N delivered by inorganic fertilizer. Plants were sampled every 14 days and sectioned into four parts: shoots, stem tips, fibrous and storage roots. Dry matter content was significantly influenced by time. Total plant dry matter was lowest in the highest inorganic N treatment. Nitrogen concentration (DWB) decreased over time and was highest in the highest inorganic N treatment. Similar vine weights were noted in N and clover treatments while number of storage roots per plant was unaffected by treatment as was weight per storage root, which increased linearly over time. No significant difference existed between the high and low N application treatment or late clover incorporation treatment in any grade of storage roots except culls, which were 90% lower in clover treatments than in N fertilizer treatments.

Adventitious buds regenerated from homogenized leaf tissue of Saintpaulia ionantha Wendl. `Crimson Frost' were micropropagated to determine types and frequencies of the variants obtained. Plants grown for one year in a greenhouse showed 67% variation and 33% normality. A higher rate of variation was observed in leaf color rather than in leaf shape. The variations in leaf color and leaf shape were 67% and 19%, respectively. In regard to flower type, greater numbers of semidouble and double types were obtained as compared to single types. Both flower types showed a much higher rate of normal (mixed) color (81%) as compared to pink, red or white (19%). An sodium dodecylsulfate polyacrylamide gel electrophoresis profile of protein extracted from leaves of the stock plants and the variants indicated no difference between them and did not reflect the variation in phenotype.
