Cucumber seedlings have a "root amount", is it really good?
Strong roots are the basis for high yields of vegetables, and each grower wants to grow large amounts of vegetables. Of course, the large amount of root is relatively speaking, not all the "roots" are as good as possible, such as the adventitious root.
What is the adventitious root?
Adventitious roots are the roots that occur on the stems or leaves of plants. In most cases, adventitious roots are caused by plant organ injuries or external factors such as hormones and pathogenic microorganisms, and thus manifest as plant regeneration reactions.
Cucumber grafting technology is a major technical measure to overcome the continuous cropping obstacles, improve plant resistance, prevent and cure cucumber wilt and disease, and obtain high yield in cucumber production and cultivation.
When the grafting is planted, if the seedlings are too deep and the seedlings are too close to the ground, the adventitious roots are easily produced on the stems of the cucumber seedlings.
Although these adventitious roots are also part of the root group, for grafting cucumbers, it is more harmful than to benefit to retain and even cultivate such adventitious roots.
The disadvantages of cucumbers
â— First, the presence of adventitious roots in the scion may cause gray disease. There are not many cases of gray disease on cucumbers, but all plants with gray disease are caused by the roots of the scion.
â— Secondly, the scion is easy to show a layer of wax on the melons, which will seriously affect the brightness of the melons and affect the quality of the melons.
â— Finally, these uncertain roots are often exposed and are susceptible to death or infection due to the external environment.
The strong root in the true sense refers to the thick main root, lateral roots and a large number of capillary roots in the soil. The cultivation of strong roots measures must also be carried out around these three types of roots. Although cucumbers are prone to roots, sometimes it is necessary to deliberately avoid the generation of adventitious roots, especially the adventitious roots on the scion. Therefore, whether it is seedling stage or adult stage, it is necessary to cultivate the main lateral roots and capillary roots in the soil and reduce the occurrence of adventitious roots.

Polyhydroxyalkanoates (PHAs) comprise a group of natural biodegradable polyesters that are synthesized by microorganisms. However, several disadvantages limit their competition with traditional synthetic plastics or their application as ideal biomaterials. These disadvantages include their poor mechanical properties, high production cost, limited functionalities, incompatibility with conventional thermal processing techniques and susceptibility to thermal degradation. To circumvent these drawbacks, PHAs need to be modified to ensure improved performance in specific applications. In this review, well-established modification methods of PHAs are summarized and discussed. The improved properties of PHA that blends with natural raw materials or other biodegradable polymers, including starch, cellulose derivatives, lignin, poly(lactic acid), polycaprolactone and different PHA-type blends, are summarized. The functionalization of PHAs by chemical modification is described with respect to two important synthesis approaches: block copolymerization and graft copolymerization. The expanded utilization of the modified PHAs as engineering materials and the biomedical significance in different areas are also addressed.
