Agglomerating seeds to enhance native seedling emergence and growth

Seedling emergence response to temperature in safflower: measurements and modeling

Quantitative information about the response of seedling emergence totemperature for safflower (Carthamus tinctorius L.) is rare. The main objective ofthe present study was to develop a model for predicting days to emergence forsafflower as influenced by the temperature. In this regard, a field experiment with arange of sowing dates and four safflower cultivars were conducted to describe theresp...

Seedling emergence and growth of sugarbeets as influenced by surface and incorporation applications of petroleum mulches

Competitive suppression of Quercus douglasii (Fagaceae) seedling emergence and growth.

Reduced recruitment of blue oak (Quercus douglasii) seedlings in California grasslands and woodlands may result from shifts in seasonal soil water availability coincident with replacement of the native perennial herbaceous community by Mediterranean annuals. We used a combination of container and field experiments to examine the interrelationships between soil water potential, herbaceous neighb...

Germination of C0,-enriched Pinus taeda L. seeds and subsequent seedling growth responses to CO, enrichment

1. Pinus tuedli seeds, developed under ambient or elevated (ambient + 200 pl1 I) [CO,], were collected from Duke Forest, North Carolina, USA in October 1998. Seeds were germinated in nutrient-deficient soil in either ambient or elevated [COJ (ambient + 200 p11 ') greenhouse chambers and allowed to grow for 120 days. 2. Seeds that developed in elevated [COJ had 91 and 265% greater weight and lip...

response of bush bean (phaseolus vulgaris l.) seedling emergence and growth to different vermicompost amounts

recently, increase in crop production depends on better seedling establishment, emergence rate and uniformity. thus, an experiment was carried out in a randomized complete block design with 8 fertilizer treatments and 4 replications in 2008 at sari agricultural sciences and natural resources university. the aim of this research was to evaluate effect of vermicompost (vc) on bush bean seedling e...
