The fungus may also infect stub ends of stems from which flowers have been cut . Detailed studies have been performed of the SAR Doppler spectrum of waves and the potential of along-track interferometry for measuring surface currents . Occasionally oedema does appear on plants that have been kept relatively dry and have grown under conditions of low humidity . These data have resulted in a series of quantitative scientific findings and theoretical advances in upper-ocean and lower atmosphere dynamics and in polar ice studies . Using spatial statistics , this information can be exploited to characterize morphological prototypes , describe scaling properties , and derive classification maps ( e.g ., Herzfeld 1993 ; Herzfeld et al ., 1993 ) . For example , extremely valuable data have been obtained on surface and internal waves , fronts , eddies , variations in bottom topography / bathymetry , upwellings , small-scale and mesoscale currents , rainfall variations , surface wind speed and stress , atmospheric convection , sea ice motions , marginal ice-zone processes , ice age , leads , polynyas , vessel wakes , surfactant / oil distributions , and a variety of other processes that give rise to subtle variations in surface roughness detectable by SAR . At planting time you should also provide two to four inches of an organic mulch such as wood chips , pine needles , or compost . Instead , we briefly describe a few sample applications and their corresponding data requirements . If you discover iris borer damage early in the season , you can crush the insect while it is inside the leaf or remove the infested leaf . Conditions which keep the soil moist , such as overwatering , poor soil drainage , inadequate light , and crowding of plants , favor the development of root rot .
