Utilization of the night-interruption phenomenon to hasten the seed increase of long-day cereals during short-day regimes in California and Arizona

Creator:

Ebeltoft, David C.

Abstract:

Tests were carried on in growth chambers and in the field to determine if the harvest of daylength-sensitive long-day cereals grown during the winter in Arizona could be hastened 30 days by the use of night interruption. Two durum lines which were near-isogenic for sensitivity to daylength were used throughout...

Perception and reproductive response of common beans (Phaseolus vulgaris L.) to photoperiod

Creator:

Privett, Diane Winters

Abstract:

Three Oregon snap beans were tested for photoperiodic response on the basis of their overall flowering patterns. Oregon 1604 and Oregon 4848 showed the same cumulative flowering curves and percent pod set under both 11 hour SD and 16 hour LD photoperiods. Under SD, Oregon 2065 produced a similar flowering...

Introducing and validating a high-throughput bud break sensor

Creator:

Kleinknecht, George J.

Abstract:

Bud break is a key adaptive trait that can help us understand how plants respond to a changing climate from the molecular to landscape scale. Despite this, acquisition of bud break data is currently constrained by cost, scale, and a lack of information at the plant scale on the environmental...
