Warm night temperature advance pecan tree growth

Greenriver pistillate flower development
     Just two days ago I posted a photo of the female flowers on a Greenriver shoot. On Monday, the pistillate flowers were just peaking out between emerging leaves (photo above, left). Today, the pistillate flowers of Greenriver are clearly visible and much enlarged (photo above, left). In just two days, our trees have made impressive growth,  all due to warm nighttime temperatures. Monday night/tuesday morning the mercury only dropped to 65 F, while last night, temperatures bottomed out at 67 F.  Pecan is a warm weather crop and what we have seen in just the past two days confirms that fact.
